The methods by which dogs are trained vary between methods involving mainly negative reinforcement and positive punishment (aversive-based methods) and methods based essentially in positive reinforcement and negative punishment (reward-based methods). However, the use of aversive-based methods is highly controversial. While some people defend their merits, others are concerned with their potential negative effect on dog welfare. To date, some studies have been performed aiming to assess the effects of aversive- and rewardbased methods on the welfare and behaviour of dogs. In the present paper we perform a comprehensive review of those studies with the aim of characterizing the state of the art of scientific knowledge of the topic. Generally, the published studies suggest that the use of aversive-based methods is correlated with indicators of compromised welfare in dogs, namely stress‐related behaviours during training, elevated cortisol levels and problematic behaviours such as fear and aggression. However, there are a number of limitations that prevent any strong conclusion from being drawn. First, a considerable proportion of the studies relied upon surveys rather than on objective measures. Second, they focused on sub-populations of police and laboratory dogs and, thus, only represent a small portion of dogs undergoing training. Finally, the empirical studies have concentrated mainly on the effects of shock-collar training, which is only one of several tools used in aversive-based training, and, in some studies, the description of the training methodologies lacks details. Here we present a description of the published studies, discuss their limitations, debate other aspects that, in parallel with the nature of the training methods, may affect dog welfare, and point to future directions for research on the topic.

One Welfare describes the interconnection between animal welfare, human wellbeing and their physical and social environment. The SARS-CoV-2 virus is the cause of COVID-19 and emerged as a human pathogen in 2019 although is thought to have a zoonotic source. The original wildlife reservoir and any potential intermediate hosts have not yet been identified. The combination of the virus zoonotic condition together with the impacts of disease control measures has exposed clear interconnections between animals, people and their environment from both a health and a welfare perspective. The One Welfare Framework comprises five sections that can help understand the different One Welfare levels on which the COVID-19 pandemic has impacted the world. This paper uses the One Welfare Framework to provide an overview of examples, within each of the five sections, where evidence is and/or can be made available to document COVID-19 impacts on One Welfare. The paper identifies a number of areas where further research and evidence gathering is required to better understand the different One Welfare impacts. Based on evidence summarised in this paper the author recommends that those responsible for managing the COVID-19 impacts and for planning the future recovery phase of the pandemic should consider adopting a holistic approach, including both health and welfare, by adopting & One Health, One Welfare& policies.

Tension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and surgical (Surgical) castration of weaner (7–10 months old) and mature (22–25 months old) bulls with and without pain management (NSAID (ketoprofen) or saline injected intramuscularly immediately prior to castration). Welfare outcomes were assessed using a range of measures; this paper reports on some physiological, morbidity and productivity-related responses to augment the behavioural responses reported in an accompanying paper. Blood samples were taken on the day of castration (day 0) at the time of restraint (0 min) and 30 min (weaners) or 40 min (mature bulls), 2 h, and 7 h; and days 1, 2, 3, 7, 14, 21 and 28 post-castration. Plasmas from day 0 were assayed for cortisol, creatine kinase, total protein and packed cell volume. Plasmas from the other samples were assayed for cortisol and haptoglobin (plus the 0 min sample). Liveweights were recorded approximately weekly to 6 weeks and at 2 and 3 months post-castration. Castration sites were checked at these same times to 2 months post-castration to score the extent of healing and presence of sepsis. Cortisol concentrations (mean ± s.e. nmol/L) were significantly (P < 0.05) higher in the Band (67 ± 4.5) compared with Surgical weaners (42 ± 4.5) at 2 h post-castration, but at 24 h post-castration were greater in the Surgical (43 ± 3.2) compared with the Band weaners (30 ± 3.2). The main effect of ketoprofen was on the cortisol concentrations of the mature Surgical bulls; concentrations were significantly reduced at 40 min (47 ± 7.2 vs. 71 ± 7.2 nmol/L for saline) and 2 h post-castration (24 ± 7.2, vs. 87 ± 7.2 nmol/L for saline). Ketoprofen, however, had no effect on the Band mature bulls, with their cortisol concentrations averaging 54 ± 5.1 nmol/L at 40 min and 92 ± 5.1 nmol/L at 2 h. Cortisol concentrations were also significantly elevated in the Band (83 ± 3.0 nmol/L) compared with Surgical mature bulls (57 ± 3.0 nmol/L) at weeks 2–4 post-castration. The timing of this elevation coincided with significantly elevated haptoglobin concentrations (mg/mL) in the Band bulls (2.97 ± 0.102 for mature bulls and 1.71 ± 0.025 for weaners, vs. 2.10 ± 0.102 and 1.45 ± 0.025 respectively for the Surgical treatment) and evidence of slow wound healing and sepsis in both the weaner (0.81 ± 0.089 not healed at week 4 for Band, 0.13 ± 0.078 for Surgical) and mature bulls (0.81 ± 0.090 at week 4 for Band, 0.38 ± 0.104 for Surgical). Overall, liveweight gains of both age groups were not affected by castration method. The findings of acute pain, chronic inflammation and possibly chronic pain in the mature bulls at least, together with poor wound healing in the Band bulls support behavioural findings reported in the accompanying paper and demonstrate that tension banding produces inferior welfare outcomes for weaner and mature bulls compared with surgical castration.

Tension-band castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the devices as a humane castration method. Furthermore, retailers encourage delaying castration to exploit the superior growth rates of bulls compared with steers. Two experiments were conducted, under tropical conditions, comparing tension banding and surgical castration of weaner (7–10 months old) and mature (22–25 months old) Bos indicus bulls with and without pain management (ketoprofen or saline injected intramuscularly immediately prior to castration). Welfare outcomes were assessed using a wide range of measures; this paper reports on the behavioural responses of the bulls and an accompanying paper reports on other measures. Behavioural data were collected at intervals by direct observation and continuously via data loggers on the hind leg of the bulls to 4 weeks post-castration. Tension-banded bulls performed less movement in the crush/chute than the surgically castrated bulls during the procedures (weaner: 2.63 vs. 5.69, P < 0.001; mature: 1.00 vs. 5.94; P < 0.001 for tension-band and surgical castration, respectively), indicating that tension banding was less painful then surgical castration during conduct. To 1.5 h post-castration, tension-banded bulls performed significantly (all P < 0.05) more active behavioural responses indicative of pain compared with surgical castrates, e.g., percentage time walking forwards (weaner: 15.0% vs. 8.1%; mature: 22.3% vs. 15.1%), walking backwards (weaner: 4.3% vs. 1.4%; mature: 2.4% vs. 0.5%), numbers of tail movements (weaner: 21.9 vs. 1.4; mature: 51.5 vs. 39.4) and leg movements (weaner: 12.9 vs. 0.9; mature: 8.5 vs. 1.5), respectively. In contrast, surgically castrated bulls performed more immobile behaviours compared with tension-banded bulls (e.g., standing in mature bulls was 56.6% vs. 34.4%, respectively, P = 0.002). Ketoprofen administration appeared effective in moderating pain-related behaviours in the mature bulls from 1.5 to 3 h, e.g., reducing abnormal standing (0.0% vs. 7.7%, P = 0.009) and increasing feeding (12.7% vs. 0.0%, P = 0.048) in NSAID- and saline-treated bulls, respectively. There were few behavioural differences subsequent to 24 h post-castration, but some limited evidence of chronic pain (3–4 weeks post-castration) with both methods. Interpretation, however, was difficult from behaviours alone. Thus, tension banding is less painful than surgical castration during conduct of the procedures and pain-related behavioural responses differ with castration method (active restlessness in response to tension banding and minimisation of movement in response to surgical castration). Ketoprofen administered immediately prior to castration was somewhat effective in reducing pain, particularly in the mature bulls.

Cats are one of the world’s most populous companion animals, yet little is known about how the home environment is adapted relative to their needs. Outdoor access is thought to be beneficial for both the physical and mental wellbeing of cats, yet as urbanisation increases, reducing owner access to outdoor spaces, an increasing number of cats are kept strictly indoors. The impact of an indoor lifestyle on feline behaviour and welfare is little explored and poorly understood. This study used a systematic review to assess scientifically validated knowledge concerning social and physical environments and their implications for indoor cats. A total of 61 papers were analysed. Only n = 21 papers directly addressed at-home indoor scenarios with the remainder consisting of shelter/cattery (n = 27) or laboratory (n = 16) (some papers explored multiple environments). Across studies there was little evidence of rigour or systematically controlled approaches. Methods frequently used were cat-stress-scores (CSS) and ethograms, neither of which were consistently standardised, substantially reducing the ability to compare findings among studies. Numerous studies explored similar variables (i.e. provision of hiding space (n = 9)) yielding little additional knowledge. Measures of welfare and behaviour were often assessed using single parameters in controlled environments. Although this may be useful and applicable to cat experiences within shelters, catteries and laboratories, the findings do not necessarily translate to dynamic and variable household environments. Major findings include the benefits of enrichment such as hiding boxes and vertical resting spaces, as often recommended by veterinarians and feline charities. However, other advice provided, such as the provision of feeding enrichment for psychological welfare, although not necessarily disputed, appears to be scientifically untested. Additionally, despite the social environment being likely to have a substantial effect on cat welfare, it is particularly under-studied in the home, especially in terms of its complexity (e.g. presence of young children or dogs). Overall, the review identified substantial gaps relative to cat experiences and welfare in multifactorial home environments. Understanding the impact of indoor lifestyles and promoting mechanisms to minimise any negative impacts whilst promoting positive ones, remains an important, yet underexplored, area of research.

European wild boars (Sus scrofa) are kept in Swedish enclosures for hunting and meat production purposes. The sows are known to undergo behavioural changes in connection with farrowing and their natural behaviours may be compromised by the limited area of the enclosure. The general aim of this thesis was to provide detailed quantitative data on wild boar sows when farrowing in captivity and to report whether possible needs can be compromised by the limitations of an enclosure. Specifically, it was aimed to provide a quantitative and functional account of the occurrence of infanticide, and its possible relations to welfare of confined wild boars. A field study was carried out in a hunting enclosure, where 1200 hours of behavioural recordings and data from 22 farrowings were collected. The farrowing period could be divided into three phases: pre-farrowing, isolation and sociality phases (in relation to farrowing: day -14 to -1, day 1 to 8, day 9 to 14 respectively). The activity decreased during isolation and increased in the sociality phase. The average distance to other individuals increased during isolation and decreased in the sociality phase. Habitat use changed towards more protective habitats after farrowing (Paper I). Non-maternal infanticide was documented in 14 out of 22 litters. Infanticide, typically performed by an older and larger sow than the mother, caused the deaths of all neonates in all but one affected litters. We found no effect of relatedness. A questionnaire sent to 112 owners of enclosures in Sweden and Finland resulted in 62 responses. Although the owners were often not able to provide exact figures on reproduction and mortality, nonmaternal infanticide was reported to be the most common cause of piglet mortality. The occurrence of infanticide was unrelated to size of enclosure and to variations in husbandry routines. All together results may suggest that non-maternal infanticide is part of the normal behavioural repertoire in wild boars (Paper II). The studies of this thesis reveals the farrowing period as the most dynamic and perhaps most challenging for wild boar sows in enclosures. There are serious welfare concerns in the husbandry of wild boars in Swedish enclosures. The most obvious welfare problem is non-maternal infanticide, where both sows and piglets are assumed to suffer, and where the outcome from the action must be considered unacceptable. If wild boar husbandry shall be equated with other animal husbandry in our society, it needs to be regulated to overcome many of the presented potential welfare problems in this thesis.

Many farm, laboratory, zoo and companion animals experience some form of maternal deprivation. This is typically via separation from their mothers earlier than would happen in free-living populations, in some cases even while young are still dependent upon milk. Maternal deprivation may also occur in a qualitative way, via inadequate maternal care, perhaps caused by inexperience or by restrictive environments that limit maternal behaviours. In this paper we review evidence on the link between early separation from the mother and abnormal behaviour from a wide range of sources, including the early primate studies in this field, more recent examples from zoo and commercially reared animals, and human examples from studies of institutionalised children. We discuss factors that seem to influence the magnitude of later effects, such as developmental stage and age at separation, and whether separation is gradual (i.e. more similar to natural separation) or abrupt (as often the case in captivity). In these instances, however, maternal deprivation is just one aspect of a suite of changes that occur when infants are separated from their mothers. In the second part of the paper we therefore review the few cases where maternal loss per se has been investigated, and studies showing lasting affects of qualitative aspects of maternal care. We then look at the possible mechanisms underlying maternal deprivation-induced stereotypic behaviours including potential frustration of specific motivations, and lasting, more pervasive changes for instance in temperament or motor control. Finally, we discuss the practical and welfare implications of the effects of maternal deprivation, and suggest some topics for future research.

In “Life in a variable world”, Mike Appleby asserts that environmental stimulation forms a large and infinitely variable continuum. This property is reflected in the organisation of behaviour; Appleby argues that there are no distinct optimal states or ‘needs’ towards which an animal’s behaviour is directed. Animals merely respond towards the range of stimuli available to them, sometimes in adaptive, sometimes in maladaptive fashion. The distinction between natural and artificial environments, and normal and abnormal behaviour, thus loses much of its meaning. Well-being becomes a relative value, emerging out of a complex multiplicity of underlying factors affecting the animal’s behaviour. This would make it impossible to predict with any amount of certainty under which circumstances well-being may or may not arise. Appleby therefore proposes that an external frame of reference is needed to establish desirable features of environmental design. He concludes that cost-benefit analysis may provide the ‘optimal’ logical framework for informed decision-making on problems of animal welfare. The value of this paper is that it puts forward variability and complexity as issues which, in an animal welfare context, need in-depth consideration in their own right. The interaction of animals with their environment, the paper argues, is too multifaceted and complex to warrant a definition of welfare in terms of distinct ‘needs’. Such an argument is timely, given the growing scientific interest in animal cognition and decision-making. It also may positively affect practical issues of environmental design, implying that man-made housing environments, though artificial by definition, could be made sufficiently complex to generate a satisfactory level of welfare. This may stimulate institutions which formerly felt forced to create wildlife safari parks on their premises (with all the accompanying resentment), to take a more constructive attitude in designing appropriate housing systems. Despite my sympathy with the overall theme of the paper, however, I do not agree

In an effort to mitigate piglet acute responses to surgical castration, the procedure can be preceded by injections of a local anaesthetic. Regardless of potential benefits at castration, the impact of local anaesthetics on piglet welfare following the procedure remains under-documented. The present paper is based on data collected in two separate castration studies investigating the impact of injection with procaine, using different injection methods, different volumes of injected drug and different timing of injection, on behavioural responses of 3–4 day old piglets, as measured by indicators of social motivation immediately after castration (Study 1 and 2), as well as behaviours recorded continuously for 10 min upon return to the home pen (Study 2 only). Study 1 involved 597 piglets, and 13 treatments: castration without anaesthesia (CC), local anaesthesia followed by castration involving all combinations of two methods of injection (intra-funicular and intra-testicular) and four intervals between injection and castration (2.5, 5, 10 and 30 min), and sham handling separated by the same four intervals (SH). Study 2 involved 290 piglets and 5 treatments: castration without anaesthesia (CC), castration after intra-testicular injections of 0.5 or 0.3 mL of procaine per testis, and sham handling with either one (SH1) or two stays in a castration bench (SH2). Across both studies, piglets injected with procaine showed signs of reduced motivation to approach their siblings in the social motivation test compared to controls castrated without anaesthesia or sham handled. The indicators of social motivation did not differ from the controls in case of castration 30 min after drug injection. In addition, responses shown in the social motivation test were less impacted after injection of 0.3 compared to 0.5 mL of procaine per testis. In Study 2, piglets injected with 0.5 mL of procaine appeared to be less active at the udder, and displayed more huddled up postures, immediately upon return to the home pen, as compared to piglets injected with 0.3 mL of procaine or the controls castrated without anaesthesia or sham handled. Altogether, the results suggest that injections with a procaine-based local anaesthetic negatively impact the responses of piglets in a test of social motivation as well as the home-pen behaviour of piglets in the early post-operative period. The present results call for attention towards the post-surgical phase, but understanding the potential welfare impacts as well as the motivational changes underlying these findings require further study.

Effective management of pain is critical to the improvement of animal welfare. For this to happen, pain must be recognised and assessed in a variety of contexts. Pain is a complex phenomenon, making reliable, valid, and feasible measurement challenging. The use of facial expressions as a technique to assess pain in non-verbal human patients has been widely utilised for many years. More recently this technique has been developed for use in a number of non-human species: rodents, rabbits, ferrets, cats, sheep, pigs and horses. Facial expression scoring has been demonstrated to provide an effective means of identifying animal pain and in assessing its severity, overcoming some of the limitations of other measures for pain assessment in animals. However, there remain limitations and challenges to the use of facial expression as a welfare assessment tool which must be investigated. This paper reviews current facial expression pain scales (“Grimace Scales”), discussing the general conceptual and methodological issues faced when assessing pain, and highlighting the advantages of using facial expression scales over other pain assessment methods. We provide guidance on how facial expression scales should be developed so as to be valid and reliable, but we also provide guidance on how they should be used in clinical practice.

Over the past two centuries, the typical life of dogs has changed dramatically, especially in the Global North. Dogs have moved into human homes, becoming human companions. In many respects, this change seems to have led to improvements in dog welfare. However, the shift into family homes from the free-roaming lifestyle characteristic of dogs as they lived and co-evolved with humans in the past, has created a typically more confined and isolated lifestyle for dogs. In addition, over the same period, selective breeding of dogs, largely driven by human aesthetic ideals and concepts of breed purity, has transformed dog populations. In this discussion paper, based on a narrative literature review, we compare the welfare of companion dogs with that of modern village dogs. We adopt this comparison because dogs have lived in ways resembling village dog life for most of their history. As such, the comparison may serve as a good basis for assessing the effects of the ‘petification’ of dogs. We argue that compared to the typical village dog, the typical modern suburban or urban companion dog experiences good welfare in a number of respects. This is especially the case when it comes to security, satisfaction of nutritional needs (though companion dogs have problems with a high prevalence of obesity), and proper veterinary care. However, in other ways the modern companion dog often suffers from a range of human-created challenges leading to poor welfare. We examine two key challenges for companion dogs: 1) unrealistic social demands that can lead to anxiety, depression, and aggression, and 2) ill devised breeding schemes that result in breeding-related diseases for many companion dogs.

Music can have powerful effects on human health and wellbeing. These findings have inspired an emerging field of research that focuses on the potential of music for animal welfare, with most studies investigating whether music can enhance overall wellbeing. However, this sole focus on discovering what effects music have on animals is insufficient for advancing scientific and practical understanding of how music can be used as an enrichment tool and can also lead to problems in experimental design and interpretation. This paper argues for a different approach to the study of music for welfare, where music is used to address specific welfare goals, taking account what animals hear in music and selecting or creating ‘musical’ compositions that test current hypotheses about how music is able to influence animal behaviour and physiology. Within this conceptual framework, we outline the process through which perceptual abilities influence welfare outcomes and suggest reframing music for welfare research as Auditory Enrichment Research which adopts a targeted approach that does not purpose music as an all-round welfare enhancer but rather investigates whether auditory enrichment can ameliorate specific welfare problems based on species-specific perceptual abilities, needs, and welfare goals. Ultimately, we hope that these discussions will help to bring greater unification, vision, and directionality in the field.

This study aimed to apply qualitative behaviour assessment (QBA) to horses farmed in single boxes, in order to investigate their emotional state and explore its association with indicators of human-animal relationship. A fixed list of 13 QBA descriptive terms was determined. Three assessors experienced with horses and skilled in measuring animal behaviour underwent a common training period, consisting of a theoretical phase and a practical phase on farm. Their inter-observer reliability was tested on a live scoring of 95 single stabled horses. Principal Component Analysis (PCA) was conducted to analyse QBA scores and identify perceived patterns of horse expression, both for data obtained in the training phase and from the on-farm study. Given the good level of agreement reached in the training phase (Kendall W = 0.76 and 0.74 for PC1 and PC2 scores respectively), it was considered acceptable in the subsequent on-farm study to let these three observers each carry out QBA assessments on a sub-selection of a total of 355 sport and leisure horses, owned by 40 horse farms. Assessment took place immediately after entering the farms: assessors had never entered the farms before and were unaware of the different backgrounds of the farms. After concluding QBA scoring, the assessors further evaluated each horse with an avoidance distance test (AD) and a forced human approach test (FHA). A MANOVA test was used to assess the association of the AD and FHA tests with the on-farm QBA PC scores. The QBA approach described in this paper was feasible on farm and showed good acceptability by owners. In the analysis of on-farm QBA scores, the first Principal Component ranged from relaxed/at ease to uneasy/alarmed, the second Component ranged from curious/pushy to apathetic. Horses perceived as more relaxed/at ease with QBA showed less avoidance during the AD test (P = 0.0376), and responded less aggressively and fearfully to human presence in the FHA test (P

Temperament, i.e. consistent inter-individual differences in behavior, has been documented in many species. Especially, boldness-shyness continuum is the ecologically relevant trait most frequently used to describe temperament among species. Reactions along the bold-shy axis demonstrate an organism’s ability to cope with environmental conditions and reflect its response to environmental stress. Our study investigated the existence of boldness-shyness continuum in 16 captive Antillean manatees (Trichechus manatus manatus) housed in 2 zoological parks. We first aimed to establish a valid methodology to measure boldness and shyness using behavioral tests. Additionally, our study explored 2 other potential temperament dimensions: sociality and reactivity to humans, and their association with boldness. Finally, since animals were kept under human care, we investigated human perception on manatees’ temperament. We conducted behavioral tests i.e. novelty tests involving novel objects, a novel sound, and an unfamiliar human. We recorded behaviors related to exploration as well as social interactions (i.e. physical proximity, social contacts) and we assessed manatees’ reactivity to humans through a participation score during hand-feeding sessions. Finally, we collected keepers’ subjective impression about individuals’ temperament through traits rating method. To our knowledge, this is the first paper that tested manatees’ reactions to different novel stimuli in order to determine their temperament. Our results first allowed us to identify the most relevant stimuli and variables to measure boldness and to classify individuals as bolder or shier. Individuals characterized as bolder displayed significantly more approach, longer approach and more contact toward stimuli than shier individuals. Moreover, boldness score was significantly associated with physical proximity with conspecifics, as well as with the participation score to hand-feeding sessions in one zoo. Finally, surveys completed by keepers were reliable and positive associations were found between rated items and behavioral observations. These findings support that as many species, manatees demonstrate boldness-shyness traits. More investigations on a larger sample size are needed to explore manatees’ temperament dimensions, and how these traits could modulate their interactions with their conspecifics and their environment. Studying manatees’ temperament could help improving the management and welfare of the species under human care. It could also facilitate their management in wildlife reserves by understanding manatees’ movements and evaluate the anthropogenic impact on wild populations.

The growing recognition of animals as individuals has broader implications for farm animal welfare research. Even under highly standardized on-farm conditions, farm animals show heterogeneous but individually consistent behavioural patterns towards various stimuli, based on how they appraise these stimuli. As a result, animal welfare is likely to be highly individual as well, and studying the proximate mechanisms underlying distinct individual behaviour patterns and appraisal will improve animal welfare research. We propose to extend the framework of affective styles to bridge the gap between existing research fields on animal personality and affective states. Affective styles refer to consistent individual differences in emotional reactivity and regulation and can be predicted by baseline cerebral lateralization. Likewise, animals with consistent left or right motor biases—a proxy measure of individual patterns in cerebral lateralization—have been shown to differ in their personality, emotional reactivity, motivational tendencies or coping styles. In this paper, we present the current knowledge of the links between laterality and stable individual traits in behaviour and affect in light of hypotheses on emotional lateralization. Within our suggested framework, we make recommendations on how to investigate affective styles in non-human animals and give practical examples. This approach has the potential to promote a science of affective styles in nonhuman animals and significantly advance research on animal welfare.

Traditionally, UK equines are kept in “gilded cages”; sanitised spaces which aim to provide every comfort, whilst shielding the horse from any form of harm or distress. Horses are typically provided with a “bedroom”; a private space where they may rest on a comfortable clean bed, wear fashionable and warm clothing, enjoy plentiful food, and perhaps play with some toys. These safe spaces may extend to the provision of individually isolated turnout in relatively small, sterile squares of grass. Yet, these spaces are a far cry from the natural lifestyle of the horse. Horses are grazing animals which would naturally live in herds and cover wide spaces while seeking food with their herd-mates, and inevitably many horses whose needs are not met display unwanted behaviours such as biting, bucking, or barging. Despite this, the equine community traditionally perceives isolated, comfortable lives as the ideal for horses, often describing them as “living like kings”. The COVID-19 pandemic presented an interesting turning point: during the initial lockdown (March-May 2020), horsepeople themselves experienced life in a gilded cage. Suddenly, the human population was plunged into many of the same conditions which are seen as optimal for our horses; we had to “stay at home”, experienced a lack of social contact, restricted movement and, perhaps most importantly, a lack of choice. In this paper, we review published equine welfare research to compare the ways in which human lockdown reflects standard equine management. We compare the ways in which published literature about human responses to lockdown give insight to common equine management issues, and finally we consider the literature around human-animal relationships during lockdown, and how the culmination of these fields might alter human-equine relationships and equine welfare as we move forward. These changes have implications for the long-term treatment of equines in the UK, as well as for other companion animals who traditionally live their lives in “gilded cages”.

The Canine Behavioral Assessment and Research Questionnaire (C-BARQ©) ( http://www.cbarq.org ) has been used to measure behaviors associated with release or graduation from several assistance dog programs, however it has never been evaluated within a prison environment. This study investigated whether a modified version of the C-BARQ© can be utilized in a prison puppy-raising program (Puppies Behind Bars, PBB) to identify behaviors that are associated with dogs’ career outcomes. PBB dogs that successfully complete the program are placed as service dogs or explosives detection dogs (EDD). Dogs are released from the program as a result of behavioral or medical problems. The PBB program has more than one career outcome, facilitating an assessment of the C-BARQ© as a tool to identify specific working dog roles based on differences in C-BARQ© subscale scores. We examined the associations between subscale scores and career outcomes by comparing the scores of dogs with successful outcomes (service or EDD) with those released for behavioral reasons. We assessed the questionnaire’s application to the PBB setting and its ability to distinguish between outcomes. 314 paper copies of the C-BARQ© were completed by puppy raisers from seven correctional facilities in the New York area when their assigned dog was between 6 and 16 months old. Dogs that had successfully completed the PBB program or had been released due to behavioral issues were included, whereas dogs still in training and those released for medical reasons were excluded. A total of 271 completed C-BARQ© questionnaires were analyzed. Service dogs and EDDs were compared with released dogs to determine whether C-BARQ subscale scores were associated with outcome. Multinomial log-linear models containing one subscale score and fixed factors (age group, medical category, sex, neuter status within sex, the interaction between age group and medical category) and outcome as the dependent variable, were fitted for each subscale. Service dogs had lower stranger-directed aggression, owner-directed aggression, dog-directed aggression, dog-directed fear, dog rivalry, chasing, stranger-directed fear, and separation-related problems than released dogs. EDDs had lower trainability, dog-directed fear, dog rivalry, and attachment/attention-seeking behavior than released dogs. These findings suggest that some of the C-BARQ© subscales might be used in the future to predict outcomes for young dogs. Results show that the C-BARQ© can be applied to the PBB program; however, the omission of seven questions is recommended.

This paper describes a method in which horses learn to communicate by touching different neutral visual symbols, in order to tell the handler whether they want to have a blanket on or not. Horses were trained for 10–15min per day, following a training program comprising ten steps in a strategic order. Reward based operant conditioning was used to teach horses to approach and touch a board, and to understand the meaning of three different symbols. Heat and cold challenges were performed to help learning and to check level of understanding. At certain stages, a learning criterion of correct responses for 8–14 successive trials had to be achieved before proceeding. After introducing the free choice situation, on average at training day 11, the horse could choose between a "no change" symbol and the symbol for either "blanket on" or "blanket off" depending on whether the horse already wore a blanket or not. A cut off point for performance or non-performance was set to day 14, and 23/23 horses successfully learned the task within this limit. Horses of warm-blood type needed fewer training days to reach criterion than cold-bloods ( P 0.05 ). Horses were then tested under differing weather conditions. Results show that choices made, i.e. the symbol touched, was not random but dependent on weather. Horses chose to stay without a blanket in nice weather, and they chose to have a blanket on when the weather was wet, windy and cold (χ 2 =36.67, P 0.005 ). This indicates that horses both had an understanding of the consequence of their choice on own thermal comfort, and that they successfully had learned to communicate their preference by using the symbols. The method represents a novel tool for studying preferences in horses.

The aim of this paper is to describe the ontogeny of the circadian activity rhythms in captive-born Iberian lynx (Lynx pardinus) from birth to subadult age and to verify if they develop a bimodal circadian pattern similar to the one they show in the wild. The amount of daily activity and the circadian rhythmicity of 61 Iberian lynx (48 mother-raised and 13 hand-reared) cubs were studied in two breeding centers. During the first month of life, the cubs were active 30% of the day. Activity increased up to 50% during the following two weeks, and then it remained constant until the end of the lynx physical development. The location of the breeding center affected the amount of daily activity of the cubs probably as result of different climatic conditions. Once the lynx cubs had completed their development, there was no difference in the time spent active between wild and captive lynx. Newborns had a constant level of activity throughout the day (24 h) during the first month of life. During the second month, once they had developed sufficiently to leave the den, a crepuscular bimodal circadian rhythm started to emerge. This pattern was completely defined by the third month of life. The overlap in circadian activity was over 0.88 when comparing the sexes, breeding centers and rearing methods. However, there was a significant difference between mother-raised and hand-reared cubs – the latter being more active in the morning–, as well as between breeding centers – again due to climate differences. Finally, an overlap of 0.85 in circadian activity pattern was observed between wild and captive lynx, although the wild animals were more active at night.

Each year, the UK rears around 20–30 million pheasants and 3–6 million red-legged partridges for shooting purposes. However, welfare organisations and some members of the gamebird industry itself have raised concerns about the use of raised laying units for breeding gamebirds. Although the proportion of breeding gamebirds kept in raised systems is relatively low there is some evidence that numbers may be increasing yet the incidence and severity of the challenges to gamebird welfare when housed in raised cages has never previously been assessed. Concern has also been raised over the ethics of confining semi-wild birds in barren cages as gamebirds are deliberately bred to retain their semi-wild behaviour which may be related to flying characteristics. The Farm Animal Welfare Committee and some sections of the gamebird industry have voiced concerns that such systems are incompatible with their ethical values, suggesting that the welfare of gamebirds in cages justifies rigorous assessment. Currently, an assessment of whether cage-based breeding systems meet duty of care requirements is constrained by a lack of understanding regarding the needs of captive gamebirds. Identifying the birds’ needs is a necessary step in defining what constitutes suitable enrichment for breeding gamebirds to optimise both welfare and animal production. Any caged-laying environment must therefore take into account the breeding ecology of the species in question and, importantly, allow the birds to display behaviours necessary to maintain health and welfare. This is the first review to examine the behavioural ecology and, specifically, the breeding systems, of the ring-necked pheasant (Phasianus colchicus) and red-legged partridge (Alectoris rufus) with the aim of highlighting areas where a species-specific behaviour would indicate a requirement for a specific resource to be made available to the birds. This review highlighted possible behavioural needs for resources targeting foraging behaviours, foot and claw function, suitable materials for dustbathing and privacy areas where birds can lay eggs or escape social pressures. These behavioural needs may be met by furnishing cages with a suitable type of solid floor and perching apparatus for enabling natural foot and claw function, by provision of dustbathing material to satisfy both dustbathing and foraging behaviour and by provision of privacy areas where birds can escape unwanted social encounters or lay eggs. The outcomes of this paper form the basis with which to develop and assess the welfare impacts of enrichment strategies and to provide an evidenced-based approach to inform gamebird management, codes of practice or legislation.

Harvesting of broilers is a stressful event, whether done mechanically or manually. The use of harvesting machines might compromise animal welfare less than manual harvesting methods because it is less influenced by environmental and flock-specific factors. In this paper, a mechanical and a manual harvesting method are compared in regard to stress-induced behavioural and physiological reactions. The stationary person test and the avoidance distance touch test were applied before harvesting to estimate pre-treatment fear of humans in the flocks. We then recorded the behaviour of the flocks during harvesting and evaluated stress-induced behaviour such as wing flapping and escape behaviour. Furthermore, we took blood samples at the abattoir and analysed the corticosterone concentration and heterophil/lymphocyte ratio. In a statistical analysis, all assessed parameters were related to environmental and flock-specific factors, as well as to the risk of lesions such as haematomas and fractures. Our aim was to figure out if the use of a harvesting machine, in this case the Apollo Generation 2, puts less stress on broilers during harvesting than manual catching. The applied behaviour tests indicate the excitability and fear of humans of the flocks but are complex to interpret. Compared with mechanical harvesting, manual harvesting was more influenced by environmental and flock-specific factors such as average weight (odds ratio [OR] = 1.49; 95% confidence interval [CI] [1.11; 2.22]) or catching duration (OR = 1.79; 95% CI [1.44; 2.19]). The results verified a correlation between stress-induced behaviour and the occurrence of lesions. The risk for haematomas was influenced by escape behaviour during manual harvesting (OR = 1.07; 95% CI [1.02; 1.13]) and by bumps against the containers (OR = 1.06; 95% CI [1.05; 1.07]) and flips (OR = 6.23; 95% CI [3.99; 9.27]) during mechanical harvesting. The risk for fractures during mechanical harvesting was influenced by the occurrence of flips (OR = 2.74; 95% CI [1.07; 5.67]). The risk for wing flapping was twice as high during manual harvesting as during mechanical harvesting (OR = 2.11; 95% CI [1.82; 2.44]). The blood parameters showed no correlations with the initial behaviour test results and the assessed stress-induced behaviour during harvesting. Corticosterone concentration was strongly influenced by light intensity (beta = 3.75; 95% CI [2.55; 4.95]) and outdoor temperature (beta = 46.34; 95% CI [39.18; 53.27]) during manual harvesting. The results showed weak points of both harvesting methods, and we offer suggestions to improve animal welfare during harvesting.

There are young managers in commercial animal agriculture in the United States, United Kingdom, Asia, and other countries, who are unaware of the scientific field of animal ethology. They may have an agricultural degree with no training in animal behavior. Some have no idea that scientists have already conducted many research studies on animal behavior. In this opinion paper, the author discusses ways to cross this divide. Basic animal behavior principles should be taught to both veterinary and animal science undergraduate students. The basic information that should be taught to undergraduates is: 1) Behavioral principles of livestock handling, 2) importance of good stockmanship to improve animal productivity, 3) principles of animal learning, 4) bull, ram and boar safety, 5) the importance of behavioral needs and environmental enrichment, 6) how to recognize abnormal behaviors, and 7) formation of dominance hierarchies. This material should be in introductory courses with practical explanations about why it is important. For example, a nutritionist needs to understand how dominance behavior may reduce access to feed. When I communicate directly with students, they are eager to learn about behavior. Students should also be taught to use the major academic databases. The second step is that researchers must communicate with producers in jargon-free language. The third step is training graduate students for management jobs on farms or research careers in industry. In the developed countries, there is a shortage of academic positions for new Ph.D.’s. Graduates in animal behavior subjects can have excellent careers outside of academia. Training in animal behavior may help them influence the policies of their employers to improve animal welfare. There are also factors in the future that may block free flow of scientific information. Unfortunately, some research results remain proprietary commercial industry information and they are not published in the scientific literature. To promote the spread of knowledge, academic researchers should avoid signing long-term non-disclosure agreements with industry. These agreements may block scientific publication. Everybody in the field of animal behavior needs to communicate outside their field and explain why behavior is important.

a b s t r a c t In this paper our first aim was to investigate the association between behaviour coding based on a test battery called the FIDO Personality test for dogs (Canis familiaris) and a subjective rating given by dog owners. For the latter we asked dog owners to fill in the Dog Personality Questionnaire (DPQ) which established four personality traits for dogs: Stranger-directed Sociability, Activity, Aggressiveness and Trainability. The FIDO Personality test consists of a series of subtests in which we utilised an ethogram and measured different aspects of dog behaviour. Prior to this study we established a set of possible associations between the behavioural and the questionnaire variables. With regard to Trainability no correlation could be detected between any of the question- naire variables and the hypothetically corresponding test battery variables. In the case of Stranger-directed Sociability, we revealed correlation between owners' reports and the dogs' behaviour during the test situation. Those dogs which were reported 'initiative' and 'not mistrustful with unfamiliar humans' approached the experimenter with shorter latency (r = −0.25, p < 0.01; r = 0.24, p < 0.01) and played more with her than those who were scored lower on these questionnaire items (r = −0.27, p < 0.01). For the factor Activity, no correlation was found between the owners' report and the behaviour of dogs displayed in the Spon- taneous activity phase of the test battery. Association was revealed between the owners' report regarding the dogs' preference for ball games and playing and their behaviour in the corresponding subtest. Those dogs which were reported to like ball games and like playing with the owner played with the ball as well as with a tug more in the test situa- tion than those which were scored lower on the questionnaire variable 'likes fetching balls' (r = 0.47, p < 0.001; r = 0.25, p < 0.01). As regards the factor Aggressiveness, the questionnaire variable 'shows a tendency to bark' correlated with the dogs' aggressive reactions (growl, bite, attack) (r = 0.25, p < 0.01) in the Bone take-away subtest and with the 'latency of getting the DNA sample' (r = 0.30, p < 0.001) in the Getting DNA sample subtest. The results show that despite of the investigated associations there is a need for more effort to refine both questionnaire-based and behaviour-based assessment of dog personality. The second aim of our experiments was to reveal whether owner ratings on the above personality factors converged with the ratings of independent groups of observers based on the video recordings of the FIDO Personality test. First, in the case of each factor, we com- pared the degrees of ratings given by the owners and by the three rater groups with different levels of hands-on experience with dogs. We found no difference in the case of Stranger- directed Sociability, Activity and Trainability (F(3, 128) = 1.17, p = 0.17; F(3, 128) = 0.99, p = 0.4; F(3, 128) = 1.6, p = 0.18 respectively) but there was a significant variability in judging Aggres- siveness (F(3, 128) = 2.86, p = 0.04). In the case of Stranger-directed Sociability, Activity and

a b s t r a c t Dogs (Canis familiaris) pose a significant threat to kiwi (Apteryx spp.) through predation. In an attempt to balance kiwi conservation and the need for dogs to be used for hunting purposes in kiwi habitat, the New Zealand Department of Conservation (DOC) developed the Kiwi Aversion Training (KAT) programme. KAT involves a training session in which a dog is presented with KAT stimuli (stuffed kiwi, frozen kiwi, and kiwi feathers) and a brief period (0.5-1.5 s) of aversive electrical stimulation from an electric shock collar is applied when the dog makes contact with the training stimuli. This paper reports three experiments: (1) investigating whether dogs can learn to avoid the KAT stimuli through aversion training; (2) investigating maintenance of aversion to the KAT stimuli 1 month after initial training; and (3) investigating maintenance of aversion to the KAT stimuli 1 year after initial training. All dogs showed aversion responses to the KAT stimuli during the initial KAT training and also when exposed to the KAT stimuli 1 month after training without an electric collar being worn. 1 year after initial training, 87% (48/55) of dogs avoided the KAT stimuli. This research indicates that KAT effectively produces aversion towards the KAT stimuli that generalizes to another location, is independent of the electric collar being worn, and that lasts at least 1 year after training.

Assessment of chicken welfare using camera surveillance of behaviour has great potential as a supplement to good stockmanship and as an aid to improving flock management. Suitable cameras are now readily available and the automated analysis of the lengthy video sequences from the cameras can be accomplished from statistical descriptors of the ‘optical flow’ patterns produced by flock movements. However, although optical flow measures have been shown to correlate with welfare outputs such as mortality, hockburn, pododermatitis and gait score, it is not yet clear how the optical flow algorithms achieve this – i.e. what variation in behaviour of individuals the cameras are picking up. The aim of this paper is to clarify the relationship between optical flow, behaviour and welfare by correlating optical flow (mean, variance, skew and kurtosis) taken from 15 min video sequences of commercial broilers at 25 days of age with bird behaviour recorded from the same sequences and with welfare measures from the same flocks (n = 24). There were no significant between-flock correlations (r2) between mean optical flow and % birds walking, % sitting/lying, walking speed or an estimate of the numbers of birds walking continuously for 10 s. or longer (p > 0.02, 2-tailed). Mean % birds walking was, however, significantly and negatively correlated with hock burn (r2 = −0.44 p 0.02) but were significantly and positively correlated with the number of birds walking continuously for at least 10 s (for skew, r2 = 0.51, p We conclude that there is no simple connection between optical flow and behaviour or between the behaviour recorded here and mortality, hockburn, pododermatis and gait score. However, reduced numbers of birds walking continuously for 10 s or more appear to be responsible for the increased kurtosis of flow in flocks with higher (less good) gait scores. Optical flow measures correlate more strongly these welfare outcomes than any single behavioural measure.

This paper presents arguments for, and evidence in support of, the important role of pleasure in animals’ lives, and outlines its considerable significance to humankind’s relationship to other animals. In the realms of animal sentience, almost all scholarly discussion revolves around its negative aspects: pain, stress, distress, and suffering. By contrast, the positive aspects of sentience – rewards and pleasures – have been rarely broached by scientists. Yet, evolutionary principles predict that animals, like humans, are motivated to seek rewards, and not merely to avoid pain and suffering. Natural selection favours behaviours that enhance survival and procreation. In the conscious, sentient animal, the drives to secure food, shelter, social contact, and mates are motivated by desire (appetitive behaviour) and reinforced by pleasure (consummative behaviour). This is reflected in animals’ behaviour in the realms of play, food, sex, and touch. Despite the heuristic value of interpreting animal behaviour through the proximate (experiential) lens, scholarly study of animals remains entrenched almost exclusively in the ultimate (evolutionary) sphere. Not just science but also ethics suffer for this, for when we see animals as only the products of a competitive struggle for survival, we risk overlooking the positive qualities of their lives. Pleasure has moral import for such practices as factory farming and laboratory research, for it amplifies the moral burden of depriving animals the opportunity to lead fulfilling, enjoyable lives.

In this paper, we review the scientific literature on maternal behaviour in commensal house mice and laboratory mice. Similar to other altricial species, female mice prepare a nest before parturition. Once the pups are born, nursing is the main part of maternal behaviour, and pups are weaned through a gradual non-aggressive process after about 3 weeks. Mice are social and both males and females show parental behaviour. Female mice giving birth at about the same time form communal nests, where pups are also communally nursed, a phenomenon that may confer benefit in inclusive fitness. However, social living may also be risky with conspecifics being the main predators of pups. A distinct aggressive behaviour pattern shown by pregnant and lactating female is thought to protect nest and pups against such attacks. Maternal aggression is influenced by the presence of pups and by litter size and composition. Communication through external stimuli from the pups contributes to maintaining maternal behaviour, thereby influencing pup growth. Handling of infants and pre- and peri-natal stress affects maternal behaviour. When resources are limited, females may reduce litter size through infanticide; however, the phenomenon of maternal cannibalism under normal laboratory conditions is poorly understood. Many studies included in this review use only standard tests to measure maternal behaviour, and more ethological research would be valuable to understand problems with reproduction in laboratory strains as well as to understand the influence of different housing conditions. We would like to thank Robert Eriksson, Bo Algers, Hanno Würbel, Dan Weary and an anonymous referee for useful comments on earlier versions of this manuscript.

With the development of laboratory animal science, increasing attention has been given to the possible influence of housing and husbandry on the behaviour and welfare of laboratory animals as well as on the scientific integrity. With the present paper, we aim to contribute to this knowledge by reviewing existing literature on how social factors influence laboratory rodents and non-human primates. We use social ecology in the wild as a starting point to understand experimental studies of these social species. Laboratory studies show that preweaning social experiences, and lack thereof, affect the development of social skills and capacity to cope with stressful situations in both primates and rodents. Studies of deprivation, of preference and of demand indicate that both rodents and primates are highly motivated to interact with conspecifics. When housed alone, rodents and primates typically show a more ‘anxious’ reaction in behaviour tests, and are more profoundly affected by certain stressors, although there seem to be some differences in how rodent males and females react to different social situations. However, for social housing to be beneficial for the animals, compatible and stable groups are crucial. When forming groups of monkeys in captivity, the age and sex of individuals and their relative age difference, the taxonomic membership of the animals as well as the introductory technique are factors of importance for success. Kinship is also of importance for the compatibility of both rodent and primate groups. Social instability through changes of group composition is apparently stressful, resulting in behavioural and physiological alterations in both rodents and primates. The effects of social conditions around testing have been given much less attention, but several studies show that animals react differently in behaviour tests when tested in group than when tested individually. Altogether, the most commonly used laboratory rodents and primates belong to social species, and their behaviour and welfare are strongly affected by previous and present social environment. Factors such as group composition and stability, rank and previous social experience therefore need to be taken into account both when designing housing systems and when planning experiments and interpreting results.

The extent to which elephants hold behavioural traits in common with human beings is relevant to the ethics of how we treat them. Observations show that elephants, like humans, are concerned with distressed or deceased individuals, and render assistance to the ailing and show a special interest in dead bodies of their own kind. This paper reports helping and investigative behaviour of different elephants and their families towards a dying and deceased matriarch. We make use of long-term association records, GPS tracking data and direct observations. Records made around the time of death, shows that the helping behaviour and special interest exhibited was not restricted to closely related kin. The case is made that elephants, like human beings, can show compassionate behaviour to others in distress. They have a general awareness and curiosity about death, as these behaviours are directed both towards kin and non-related individuals.

Animals are routinely subjected to painful procedures, such as tail docking for puppies, castration for piglets, dehorning for dairy calves, and surgery for laboratory rats. Disease and injury, such as tumours in mice and sole ulcers on the feet of dairy cows, may also cause pain. In this paper we describe some of the ways in which the pain that animals experience can be recognized and quantified. We also describe ways in which pain can be avoided or reduced, by reconsidering how procedures are performed and whether they are actually required. Ultimately, reducing the pain that animals experience will require scientific innovation paired with changed cultural values, and willingness to address regulatory, technological and economic constraints.

This paper reviews the current theory and potential practical applications of research on the diet preference for grass and legumes in grazing domestic sheep and cattle. Although much of this work has focussed on grass and clover as a model system, it has wider theoretical implications and potential for practical exploitation. Research in this field is of particular relevance with the recent increased interest in maintaining and enhancing biodiversity, both in agricultural systems and semi-natural habitats. One of the most consistent findings of previous research is that sheep and cattle both eat mixed diets, showing a partial preference of approximately 70% for clover. There is a diurnal pattern to preference, with a stronger preference for clover in the morning, with the proportion of grass in the diet increasing towards the evening. Research has also shown that sheep and dairy cattle achieve higher intakes from grass and clover when these are offered as separate monocultures compared with animals grazing a traditional mixed sward. The initial findings were from studies where the animals had free choice, but similar results have been achieved in dairy cows being allocated to clover between morning and afternoon milking and grass for the remainder of the day. The intake benefits, which have been attributed to a lower selection cost, have the potential to be exploited on-farm to increase intake and production. Our increasing understanding of the factors influencing diet selection raises the possibility of developing grazing management practices to maintain and possibly enhance biodiversity. Various theories have been proposed to account for the fact that ruminants eat mixed diets. Although some, such as spatial memory and visual discrimination have been discounted, others, such as perceived predation risk and balancing nutrient intake, appear to be more valid. However, further research is still needed to explore and validate hypotheses related to these theories.

Foraging herbivores are often faced with spatial and temporal heterogeneity within the vegetation they have available to graze and therefore have to make decisions where and when to graze. The study reported in this paper investigated the influence of sward height on diet selection by horses grazing perennial rye-grass swards. The study comprised two experiments. In Experiment 1, perennial rye-grass paddocks were mown to four sward heights (heights: 3.5, 4.5, 7.5 and 15 cm) to create a patchy environment. Within each paddock one horse grazed for a period of 1 h during which residence time, number of bites and frequency of visits per patch were recorded. This was replicated with all seven horses used in the experiment. The same experiment was repeated in Experiment 2, but without mowing the field and allowing 1 week of re-growth for each paddock. During both experiments horses entered equally often but resided significantly longer on patches with long grass (15 cm) than on those with short grass (below 4.5 cm; P P

Knowledge obtained from research has been effectively transferred to the agricultural industry in some areas and poorly transferred in others. Knowledge that has been used to create a product such as a pharmaceutical or a device is more likely to be adopted by industry than a behavioral management technique. During my career, I have observed that some people will purchase a new cattle-handling system, which is designed with animal behavioral principles, but they will continue to handle cattle roughly. People are more willing to purchase new equipment than they are to use easy-to-learn, low-stress handling techniques. Even when financial benefits are clear, some people find it difficult to believe that a behavioral management method really works. From my experience, I have learned that successful transfer of knowledge and technology to industry often requires more work than doing the research. For an effective transfer of technology to take place, the method or equipment must be used successfully by the people who initially adopt it. If the new piece of equipment fails on the first or second place that attempts to adopt it, transfer to the industry may fail. In this paper, I describe a successful case study of transfer of a conveyor restrainer system, based on behavioral principles, from the research lab to US and Canadian beef slaughter plants. I also describe the successful implementation of a measurement system for auditing animal handling in slaughter plants. Based on my experience, the following steps for successful transfer of behavior research to the industry are: (1) Communicate your results outside the research community. Write articles in popular and industry magazines. Speak at producer meetings and develop websites that can be used to transfer research results into practice. (2) Choose places (e.g. farms or plants) that have managers who believe in your research, and be prepared to spend a lot of time with the first place that uses your findings. (3) Closely supervise other early adopters to prevent mistakes which could cause the method or technology to fail. (4) Do not allow your technology to get tied up in patent disputes.

Outside the scientific world, the effect of social behaviour on production is little taken into account, but the importance of this relationship has been sufficiently proven in some animal species. Nevertheless, there are scarce works that emphasise the importance of behaviour in the production of the goat. The main objective of this paper is to determine if there is a stable hierarchy of dominance in a flock of goats fed in pasture, and if this hierarchy influences somehow the diet selected in the pasture and in its production of milk and meat. The study was carried out in a flock of goats in semi-extensive grazing management. The interactions observed in the pasture during the supplementary feeding and during the milking were written down. This allowed us to determine the dominance rank. The diet was determined in the pasture by the direct observation method. The production of milk was measured daily. The meat production consisted on the weight of the kids in their first day of life and after a month. Among the most prominent results, the following should be indicated: (a) Within the herd, a clearly established, quite stable and linear hierarchic order exists. (b) The most aggressive animals are those that occupy the highest positions within the social hierarchy. (c) Age, large size and horns seem to be the physical factors that most favor dominance. (d) When more forage becomes available, differences appear in the diet chosen by dominant and subordinate animals, that is, they become more selective. In the months of greater shortage, these differences in feeding disappear, and they become more generalist. (e) The production of animals is affected by dominance. However, contrary to what might otherwise be thought, it is the middle range of goats that are the most productive.

This paper takes a closer look at the subjectivity/objectivity relationship, as it plays a role in the science of animal welfare. It argues that subjective, experiential states in animals such as well-being and suffering are, contrary to what is often assumed, open to empirical observation and scientific assessment. The presumably purely private, inaccessible nature of such states is not an inherent property of these states, but derives from their misguided conception as ‘causal objects’ in mechanistic models of behaviour. This inevitably endows subjective experience with a ‘hidden’ status. However, subjective experience should be approached on its own conceptual grounds, i.e. as a perspective, in terms of ‘what-it-is-like-to-be’ a particular individual animal. Neither behaviour nor subjective experience then can be regarded as causal objects; they form an integrated, dynamic, expressive whole. The animal is perceived as an agent, whose perspective on a given situation is manifest in the way in which it interacts with and pays attention to that situation. In this framework, concepts of subjective experience such as enthusiasm, timidity, fear or contentedness, may be defined as categories of ‘attentional style’. Testing the scientific validity and reliability of such categories requires development of a qualitative methodology for the measurement of behaviour. Starting-points for such a method are put forward for discussion.
