The aim of the study was to demonstrate correlation between selected body condition indices of roe deer Capreolus capreolus (KFI, carcass weight) and the health status of the carcass (i.e. pathological changes found through external and internal examination of the carcass) of deer killed by hunting or road traffic. The study material consisted of 34 carcasses of roe deer found dead due to road collisions or obtained through hunting in accordance with the Principles of Individual and Population Selection of Game Animals in Poland. The results showed a significant correlation between the occurrence of disease signs (especially the presence of parasites) and the mean values of indices describing the individual condition of animals (carcass weight, KFI). This confirms that the preliminary examination of game harvested and animals killed by road collisions plays an important role in inhibiting the spread of epizootic diseases and in assessing the individual condition of animals.

The objective was to verify the research hypothesis concerning a correlation between the surface area of the medullary bone and other fat indices and carcass weight. This study was also focused on identification of potential differences in the mean values of the fat parameters and carcass weight between the forest and field ecotypes of roe deer. The medullary cavity area was measured using the DIRA 200 program. Metacarpal bone III and the phalanges of the 2nd and 3rd fingers were measured as well. The investigations involved 38 females of the European roe deer Capreolus capreolus aged 3-5 years.The investigations revealed a negative statistically significant correlation between the surface area of the medullary cavity in metacarpal bone III and the kidney fat index KFI (rs = -0.483; p

Chronic pain accompanying many diseases significantly impairs the quality of life and induces various changes in the behavior of animals. The present case report describes a dog with persistent chronic pain. The clinical signs demonstrated by the dog e.g. sneezing, rubbing the viscerocranium with thoracic legs, shaking the head, and avoidance of touch, clearly suggested discomfort localized in the muzzle. The final diagnosis of nasal adenocarcinoma was reached after over a year from the appearance of the first symptoms of discomfort. In retrospect, it is clear that the changes in the dog's behavior were caused by chronic pain. Presentation of new behaviors should be a signal to the owner indicating certain disturbances in the animal's well-being. There is a need for cooperation between the pet owner, veterinary doctor, and animal behaviorist in order to regard behavioral changes as a clue for the diagnosis of pain experienced by the animal and for treatment of its causes.

The aim of the study was to assess the condition of roe deer in the closed hunting season based on the analysis of body weight and fat reserves in roe deer killed in road collisions. The research material consisted of kidneys dissected from 12 bucks, 4 does, and 5 fawns killed in road accidents between February 12 and May 10, 2020. The measurements were used for calculation of the kidney fat index (KFI) based on the formula [Bobek et al. 1984]: KFI = kidney weight with fat/kidney weight without fat. The study presents the distribution of the analyzed parameters with reference to the animal sex and month in which the animal died in the road collision. A distinct decline in the value of fat reserves expressed as the KFI index and the perirenal fat weight mass was observed in the study. In the first two months (February, March), this decrease coincided with reduced body weight, which rapidly increased in April. This may have been related to the intensive vegetation growth. Nevertheless, the costs of the breeding season (primarily in males) resulted in further weight loss in May. The analysis of carcass weight and fat reserves in roe deer killed in road collisions can complete the information about their individual condition and indirectly shows the condition of the roe deer population in the closed hunting season, i.e. in the critical period for this species (winter and the beginning of the breeding season).

The aim of the study was to assess the salivary cortisol level in search and rescue dogs during rescue search examinations. The research was carried out during open-field and disaster examinations for search and rescue dogs in Poland. Forty-one dogs took part in the study. Saliva was collected just before the search test and immediately after the search examination. The salivary cortisol level in dogs was marked and analyzed in relation to the sex, breed, type of examination, dogs' experience, and detection time. Salivary cortisol level in search and rescue dogs increases during the examination in both male and female dogs. Examination type affects salivary cortisol levels in male and female dogs. The sex of a search and rescue dog can be an important factor when choosing the specialty in which to train.

The aim of the study was to assess the relationship between the motor lateralization in dogs and the concentration of cortisol and tyrosine in their plasma during a visit to a veterinary clinic. The research group consisted of 56 dogs. Motor lateralization was tested by of an adhesive tape test. The stress intensity was assessed basing on the levels of cortisol and ft4 in the serum blood. The statistical analysis revealed that in the group of 56 dogs there were 14 left-pawed dogs, 36 right-pawed dogs, and 6 dogs did not show particular paw preference. The average cortisol levels in particular groups were as follows: 7.94 ug/dl, 3.92 ug/dl and 3.7 ug/dl, whereas the level of tyrosine in the subjects that demonstrated left-sided lateralization (mean ± SE) (1.95 ± 0.46 ng/dl) for those with right-side lateralization (1.56 ± 0.23 ng/dl) and ambilateral dogs (1.01 ± 0.22 ng/dl). The statistical calculation of Pearson's χ

The aim of this study was to assess salivary cortisol level in dogs during admission and a three-day stay in a pet hotel. The study involved 20 dogs admitted to a pet hotel for a stay lasting for at least three consecutive days. The study group consisted of 10 small dogs and 10 medium-sized dogs, eight females and 12 males. Saliva was collected each day to assess cortisol levels. A stay in a hotel is a stressful situation for dogs, as evidenced by the increase in the salivary cortisol level. The highest salivary cortisol level was observed on the day of admission to the hotel. The median salivary cortisol level in the dogs on the consecutive days was 2.7 ng/ml on admission, 2.1 ng/ml after 24 hours, and 1.9 ng/ml after 48 hours. Depending on the size of the dog, the median salivary cortisol level was 2.8 ng/ml, 2.9 ng/ml and 2.4 ng/ml in the small dogs and and 2.2 ng/ml, 1.7 ng/ml and 1.2 ng/ml in the medium sized dogs on the consecutive days.

The accumulation of cortisol in hair and claws, which grow slowly, makes it possible to retrospectively assess chronic stress levels. The study involved 47 cats from a shelter for homeless animals. Hair from the lumbosacral region and the dead part of claws from the front paw were collected. The average cortisol levels were 0.85 ng/ml in the cats’ hair and 4.56 ng/ml in the claws. There was no significant relationship between cortisol levels in hair and claws. To date, too little research has been done on the correlation between cortisol levels in the hair and claws of cats. It is insufficient to unequivocally prove the existence of such a relationship.

We developed an algorithm to classify brown hares into two age classes, juveniles (up to 1 year old) and adults (over 1 year old), based on body weight, which can be determined by both the examination of live animals and postmortem analysis. Considering the strong correlation between lens weight and carcass weight, we assumed that hares could be classified into one of the two age groups based only on carcass weight, using a logistic regression model. Using logistic regression, a model was constructed to assess the age of hares based on their body weight. For comparison with the current age-assessment method based on the dry lens weight, a logistic regression classifying the hares based on the dry lens weight was performed as well. The results of the study facilitated the development of a method to classify hares into age groups based on body weight. The proposed approach is innovative, as it allows for the determination of the age of not only culled (postmortem) but also live hares. The method is easy and does not require laboratory tests; hence, the results can be used immediately following evaluation. This method allows hares to be categorized into two age groups (juveniles and adults). With an accuracy of 97.52% and 95.45% in the case of juvenile and adult hares, respectively, the proposed approach can be widely used both in population management and scientific research.

It has been assumed that stroking relieves stress responses in dogs, and dogs with the activation of the left-brain hemisphere (right-pawed) may show better adaptation to stress conditions. The aim of the study was to determine whether the stroking stimulus induced changes in the level of selected neuroregulators in dogs&rsquo, blood and whether these changes depended on the sex and the predominance of the activity of one of the brain hemispheres. The study involved 40 dogs of various breeds and both sexes. The experimental animals were subjected to a behavioral tests (Kong test), and the levels of noradrenaline, serotonin, and cortisol were determined in their blood plasma. The results of the behavioral test revealed that most dogs exhibited increased activity of the left hemisphere. Furthermore, irrespective of the sex and paw preference, stroking the animal was found to alleviate the stress response, which was reflected in reduced cortisol levels and increased serotonin levels. It was found that the plasma noradrenaline, cortisol, and serotonin levels were lower in the female dogs than in the males. Additionally, the plasma noradrenaline and serotonin levels were higher in the right-pawed dogs than in the left-pawed dogs. The present results confirm the assumption that right-pawed dogs adapt to stressful conditions more readily.

The aim of this study was to evaluate the temperament of dogs on the basis of behavioral observations, with emphasis on 24 selected traits and behaviors. From the observations, the temperament of the dogs was determined and the animals were assigned to one of two personality groups: introvert or extrovert. The study involved 46 dogs. The agglomeration method, Pearson’s 1-r distance, and Ward’s binding method were used. As shown by the statistical analysis, 18 dogs (39%) were assessed as introverts and 28 dogs (61%) exhibited extrovert traits. To construct a model for the assessment of canine temperament using the identified traits, logistic regression was performed with the independent variables, number of extrovert traits (ETs) and introvert traits (ITs), and a dichotomous dependent variable (1 = extrovert, 0 = introvert), reflecting the assessment of the temperament of the dog based on the observations and results of the original questionnaire.

The aim of the study was to analyze the ritual of territorial vocalization of pheasant cocks. The research aim was to determine whether the duration of the ritual of the territorial vocalization of pheasant cocks depends on the season of the year or whether it is an individual feature. The work was performed based on the analysis of film recordings of 7 male pheasants recorded in the Bystrzyca Valley in Lublin (Poland). Several-minute recordings were made from April 19 to June 27, 2018 in the morning (around 6: 00-8: 00). The characteristic for the species ritual vocalization were divided into four phases. The study concluded that the average duration of individual phases of ritual vocalization in individual birds varies and is an individual value. The number flaps of the wings before and after the vocalization varies depending on the cock and is bird-specific, and depends to a small extent on the month of observation.

Search and rescue dogs are an important link in the search for missing persons. The aim of the study was to assess exam stress in search and rescue dogs and their guides. The study included 41 rescue teams taking exams of field and rubble specialties. The level of cortisol, which is the main glucocorticosteroid modulating stress reactions in humans and dogs, was analyzed. The biological material used to assess the hormone concentration was saliva collected in a non-invasive way. In total, 164 test samples were collected: two from the dog and two from the guide before and immediately after the exam. Rescue exams were shown to significantly increase salivary cortisol in both dogs and their guides. Strong interactions between cortisol levels in human&ndash, dog teams were also found with a more pronounced effect in female dog&ndash, female handler dyads.

The analysis involved wild boars from the Lublin region, Warmia and Mazury, and Wielkopolska. The study material comprised muscle tissue samples collected from 100 wild boars. We analysed loci S0008, SW1129, SW986, SW1465, SW1492, SW1514, SW2532, SW461, SW841, SW2021, and SW2496 [1, 2]. The largest number of specific alleles, i.e. in six loci, was observed in wild boars from Warmia and Mazury; in turn, there were only two alleles in the group of wild boars from Lublin, and no alleles in individuals from Wielkopolska. The average value of the observed heterozygosity was Ho = 0.51, and the average value of expected heterozygosity was He = 0.63. PIC was another analysed indicator, with its lowest value determined for wild boars from the Wielkopolska region (0.53), and the highest value (0.62) was found for the animals from Warmia and Mazury. In the study population of wild boars, we also determined the FST index, which was 0.073, and Nm had a value greater than 3 (3.15); therefore, it can be concluded that the number of migrants per generation was 3. Both coefficients confirm the possibility of gene transfer and reproduction within and between the analysed populations of the wild boars. In our study, we observed a greater genetic distance between the wild boar populations from Wielkopolska and the Lublin and Warmia and Mazury regions in spite of the smaller geographical distance of these lands. This may be caused the less extensive network of ecological corridors as well as the occurrence of anthropogenic barriers e.g. large urban centres, an extensive network of roads, and the high volume of traffic in the direction of the capital.

Populations of game are not confined to single ecosystems but function within higher-order units, e.g. ecological landscape. The basis for the establishment of the hunting complexes was the assumption that the existing game hunting grounds, i.e. the basic units implementing game management, are too small and do not cover the natural areas inhabited by game populations. Roe deer are flexible species and easily adapt to various site conditions, so they inhabit many different habitats, from large forest complexes, through small in-field tree stands and shrubs, to treeless grounds and field monocultures. The aim of the study was to determine a possible impact of environmental conditions prevailing in the hunting complexes of the Regional Directorate of State Forests (RDLP in Lublin) on the ontogenetic quality of roe deer. The study was conducted on 518 European roe deer (Capreolus capreolus) aged from 4 to 7 years (379 bucks and 139 does) harvested within hunting seasons 2010/2011–2013/2014. The results have shown that animals originating from areas with greater forest cover and denser stands are characterised by lower values of the mean ontogenetic quality parameters (carcase weight, kidney fat index, chest girth, weight of antlers) in comparison with animals from typical agricultural areas with fragmented forest complexes. These results indicate that, even in the case of such a eurytopic species as the roe deer, the ontogenetic quality differs between individual hunting complexes. The study has proved that strategies for hunting management of the roe deer should take into account the impact of the landscape structure, which provides a rationale behind creation of hunting complexes.

The aim of this study was to determine the scale of the phenomenon and the risks resulting from stings of domestic dog by bees. The material consisted of clinical interviews on dog disease history from four veterinary clin-ics. Twenty-six cases of stings were selected, in which the dog owner could positively identify the insect species that had stung a dog (on the basis of the external appearance of a dead bee or the presence of its sting). The select-ed dogs were grouped by sex and age: juveniles – aged up to 12 months and adults – aged more than 12 months. In addition, the grouping took into account the occurrence of pulmonary edema symptoms or lack thereof and the body response. Three types of body response were distinguished: a local reaction (M) in the form of erythema with edema, a large local reaction (MD), and anaphylaxis (pulmonary edema confirmed by X-ray examination). The following blood counts were evaluated: erythrocytes, leukocytes, lymphocytes, hematocrit value, hemoglobin con-centration, segmented neutrophils percentage, MCV, MCH, MCHC, as well as biochemical indices: AP, ALT, AST, creatinine, and BUN. Clinical and behavioral symptoms were analyzed with the use of a survey conducted with a randomly selected group of dog owners. To illustrate the scale of the problem, the survey on bee stings was conducted among 97 dog owners. An analysis of the coefficients of correlation between the values of the above parameters and the age of stung dogs showed that with dog’s age, there was a decrease in AP, lymphocyte and leukocyte levels, and an increase in hemoglobin levels percentage of segmented neutrophils, as well as hematocrit and erythrocyte counts. A statistically significant differ-ence was ascertained in AST, whose values were significantly higher in dogs without pulmonary edema (33.6 U/l ± 14.0) than in the group with edema (22.7 U/l ± 4.6), t (22) = 2.856; p = 0.01. A comparison of the average values of the parameters under analysis for both sexes revealed a significant difference between the average values of hemo-globin, which was significantly higher in males (16.6 g/dl ± 2.6), compared to females (14.1 g/dl ± 2.6), t (24) = 2,156; p = 0.041. The dogs were also classified into two groups according to the type of reaction: a local reaction or a large local reaction. Significantly greater differences were found in the average content of erythrocytes in dogs with a local reaction. Among all respondents, 35% reported their dogs having been stung by insects from the family Hymenoptera. Male dogs were stung twice as often as females, and almost half of the sting cases were dogs older than 4 years. Most of the stung dogs were kept in the backyard, and purebred dogs were stung more frequently than crossbreeds. Half of all cases were stings on the head, and the stung dogs usually reacted by strong hyperkinesia and slight vocalization (one point on a three-point scale).

The European Mantis (Mantis religiosa L.) is the only member of the Mantodea in Poland. Although it does not require active protection, the species is under strict protection by a regulation of the Minister of the Environment. In addition, Mantis religiosa is entered into the Polish Red Book of Animals (i.e. a list of threatened species) with the status EN. Praying Mantises are not well known in Poland, and as such, arouse great curiosity wherever encountered. In the absence of adequate knowledge about these insects and about their legal status, they are often removed from their natural habitat and taken home or to a veterinary clinic. This article describes the most important issues regarding the protection of Mantis religiosa, the dispersion of this species in Poland, and its developmental cycle. This information may prove useful to all who come into contact with these insects; including veterinarians to whom they are occasionally brought. It is important that the correct information regarding European mantises is available to the general public, as well as to the veterinarians, so that they know how to deal with the specimens found.

The aim of the work was to present contemporary pet name trends, especially for cats and dogs. It also attempts to identify the origins of pet names. The research data consisted of the pet names of patients of a veterinary clinic in the years 2014-2018. The pet names of 36,487 dogs and 14,518 cats were analyzed statistically. The results obtained revealed relationships between the animal-human relationship, the species and sex of the animals. Among the most common dog names were diminutive male names (Max) and names borrowed from culture or mythology (Nero, Ares). The most universal name was Kuba, which occurred in both male and female dogs and cats. Among cats the most numerous were those called by diminutives of the word cat (Kicia) or by female names (Zuzia) and unnamed animals. Statistical analysis indicates a link between naming and the species: there were more nameless animals among cats than among dogs. A relationship between naming and the sex of dogs and cats was also noted: males were nameless more often than females.

The aim of this study was to assess changes in parameters (body weight, fat stores, antler weight, serum creatinine level) describing the condition of individual roe deer males (Capreolus capreolus) in subsequent months of the hunting season. The idea was if the current timing of the buck hunting season affects the quality of specimens obtained from the population, which may result in distorting its reproduction-related processes. The study included 443 carcasses of bucks harvested in the Lublin region (Central Poland) from 2006 to 2011. The average carcass weight in May and June was significantly higher than in the other months. Perirenal fat weight and the kidney fat index (KFI) decreased with the progression of the hunting season. With regard to the average level of serum creatinine in blood, there was no definite trend in the variation of this parameter during the hunting season. However, a significantly higher average antler weight was observed in May compared to June. The shooting of a large number of bucks in the first weeks of the hunting season may cause the elimination of the best individuals in the habitat, which have established and maintained their territory and are fully prepared for reproduction. This results in a complete disruption of the social structure of the local deer population. A solution to this problem could be uniform distribution of volume harvested during the whole hunting season or postponing the hunting season for bucks until September, when the estrus season has finished, and the strongest males have passed on their valuable genes to the population.

Veterinary medicine is developing just as rapidly as human medicine. New technologies and workflows improving the process of treating humans are often applied in veterinary medicine. The procedure commonly used in emergency medicine is triage, that is, a system of patient segregation. In many countries, it has also proved extremely useful in the treatment of animals. Triage is a study and classification of patients according to the urgency of treatment. Its aim is mainly to recognize among many patients those that require immediate medical assistance. These are the so-called priority patients with life-threatening conditions. Animal clinics modify triage to suit the needs of veterinary patients. It improves greatly the work of clinics, especially in emergency waiting rooms. The aim of this study was to discuss the use of segregation in veterinary patients and to present our own proprietary triage protocol for the veterinary patient: Card of Veterinary Patient Pre-segregation (industrial design Rp.21948).

A novel elastic hydroxyapatite-based composite of high surgical handiness has been developed. Its potential application in orthopedics as a filler of bone defects has been studied. The biomaterial was composed of carbonated hydroxyapatite (CHAP) granules and polysaccharide polymer (β-1,3-glucan). Cylinders of 4 mm in diameter and 6 mm in length were implanted into bone cavities created in the proximal metaphysis of tibiae of 24 New Zealand white rabbits. 18 sham-operated animals were used as controls. After 1, 3 or 6 months, the rabbits were euthanized, the bones were harvested and subjected to analysis. Radiological images and histological sections revealed integration of implants with bone tissue with no signs of graft rejection. Peripheral quantitative computed tomography (pQCT) indicated the stimulating effect of the biomaterial on bone formation and mineralization. Densitometry (DXA) analysis suggested that biomineralization of bones was preceded by bioresorption and gradual disappearance of porous ceramic granules. The findings suggest that the CHAP–glucan composite material enables regeneration of bone tissue and could serve as a bone defect filler.

In breeders’ general opinion small breed females produce less numerous litters. The aim of the study was to analyse the litter size and the frequency of the gender ratio in selected small dog breeds in view of their popularity in Poland. The data set comprised information on 639 litters (in total 2578 puppies) of eight breeds, which were born between January 2003 and end December 2014. The results were statistically analysed using statistical program SPSS 20.0. Medium-size litters were observed in the analysed small dog breeds (4.034±0.1). Comparison of the selected breeds of the Fédération Cynologique Internationale (FCI) Groups showed that the mean litter size in Group IX was higher (4.36±0.08) than that in Group III (3.87±0.14) and the differences were statistically significant. The study has confirmed the hypothesis that larger females produce more numerous litters, but there are large intra-individual variations in the number of pups born in individual breeds. Additionally, the gender ratio in the puppies born in the analysed breeds was equal, despite the fluctuations in the individual breeds.
