DOMINICAN sisters , *NUNS' writings , *PRIESTS , *FRIARS , *HISTORY of religion - Abstract
This article discusses the relationship between Dominican nuns and their caregivers (priests and friars) with the help of sister-books written by the Dominican nuns themselves in the first half of the fourteenth century. My main focus will be on analysing the way religious men were described in these books and asking how this discussion was related to the everyday life of the nuns in the Dominican convents. I will suggest that the sister-books can give a new and perhaps unexpected view of the relationships between Dominican nuns and their spiritual caregivers, as these texts suggest that nuns preferred local secular priests over the friars, even though they accepted the religious authority of the latter. I will argue that although the sister-books were literary products, they had a close connection to the lived reality of nuns and that they can tell us about the interaction between nuns and religious men in their service. However, these texts also formed the ideas of nuns and kept the old attitudes towards priests and friars live, even when the interaction might have already taken other forms in practice.

The increasing incidence of type 1 diabetes observed in the past 60 years has spawned massive efforts in multiple research fields to elucidate the aetiology of this disease. While GWAS studies provide a good genetic basis for the current knowledge, it is clear that environmental triggers and their influence in disease prevalence and origin are highly important. The realization of disease heterogeneity has created a requirement for better biomarkers to complement the known autoantibody markers and to more successfully predict the severity and onset time of the disease. Such biomarkers would be needed both for prevention as well as for monitoring disease activity and response to preventive and therapeutic measures. Systematic holistic approaches concentrating on the triggering molecular mechanisms, pancreatic beta cells, immune response, as well as the influence of diet and environment, are necessary to understand the disease pathogenesis and find a cure. The current genomic knowledge is being broadened with accompanying studies in epigenetics and transcriptomic regulation, metabolomics, proteomics and lipidomics, covering the whole system from beta cells, the profile and cellular balance of the infiltrating lymphocytes, to gut microbiota and viral infections. Here we highlight interesting recent findings in type 1 diabetes research. [ABSTRACT FROM AUTHOR]

In order to determine the effective dose, the effects of orally administered ketoprofen were evaluated in pigs following intravenous challenge with Escherichia coli endotoxin. One hour after the challenge, five groups of pigs were treated with either tap water or ketoprofen (0.5 mg/kg, 1 mg/kg, 2 mg/kg or 4 mg/kg). The body temperature was measured and a total clinical score was calculated after assessing the general behaviour, respiratory rate and locomotion of the pigs. Thromboxane B
2 and ketoprofen concentrations were analysed from blood samples. Ketoprofen treatment significantly reduced the rectal temperature and total clinical scores, and lowered blood thromboxane B2 concentrations when compared with the control group. Ketoprofen plasma concentrations were lower than previously reported in healthy pigs after similar doses. The appropriate dose of orally administered ketoprofen in pigs in this model is 2 mg/kg, as the higher dose of 4 mg/kg failed to provide an additional benefit. [ABSTRACT FROM AUTHOR]- Published

The effect of ad libitum (ADLIB) feeding strategy on the fertility of the group housed sow was studied in a prospective field trial during 1.5 years. All study animals farrowed under standard farrowing circumstances in crates, and they were provided with an ad libitum feeding throughout the 30-day lactation. After weaning, animals were randomly allocated to one of the two dry sow feeding strategies (AD LIB or CONT). After oestrus detection in groups, they were artificially inseminated and moved into pregnancy pens with partially slatted floor, in groups of 40 sows each. The ADLIB sows (n = 447) were loose housed and provided with ad libitum access to 7.7 MJ/kg feed high in fibre from two feeders per group. The control sows (n = 479; CONT) were also loose housed and given a standard dry sow feed in feeding stalls once a day (2.5 kg/day. The energy content of the feed was 9.3 MJ/kg NE). The feeding strategy (ADLIB vs CONT) had no effect on pregnancy rate (85.8 vs 90.9, p > 0.05), weaning to oestrus interval (7.7 vs 7.3 days, p > 0.05), piglets born alive (11.5 ± 3.5 vs 11.6 ± 3.3, p > 0.05), stillborn piglets (1.2 ± 1.8 vs 0.9 ± 1.5, p > 0.05) nor on progesterone concentration (p > 0.05). CONT sows weaned more piglets (9.7 ± 2.2 vs 9.4 ± 2.0, p < 0.01), whereas the piglets of AD LIB sows were heavier at weaning (8.8 ± 0.9 vs 8.0 ± 1.3 kg, p < 0.05). In conclusion, ad libitum feeding with a high in fibre diet during pregnancy did not affect the reproductive performance. [ABSTRACT FROM AUTHOR]

Contents The objective of this retrospective cohort study was to clarify the effect of re-modelling the breeding unit on farrowing rate. The original study population included 63 sow herds that participated in the Finnish herd surveillance system. In these herds, the breeding units were re-modelled between 1995 and 2002. Information about the production system and other herd data for the last year before and the second year after re-modelling were available for 47 herds. The herds had an average of 68.5 (SD 45) sows per herd. Data were collected during one farm visit per herd. Initially, all herds had individual cages in their breeding units. The piggeries had either re-modelled their cages or switched to a group housing system with deep-litter, solid or slatted (partly or totally) floors. Farrowing rates were gathered from the national database, and data were tested with a linear regression model. Re-modelling did not have an effect on farrowing rate if initial reproductive performance of the herd was neglected. However, when farms were stratified according to performance prior to the beginning of study, namely into ‘farms with initially high farrowing rate’ (HF) and ‘farms with initially low farrowing rate’ (LF), the re-modelling had a significant effect on farrowing rate. In the HF farms, re-modelling caused a decrease in farrowing rate. Correspondingly, farrowing rate increased after remodelling in the LF farms. Farrowing rate was also influenced by mean parity of sows and by proportion of sows culled because of leg problems. This study could not show a profound impact of the design of the breeding unit on the fertility of the sow in the modern commercial production environment if the farm’s reproductive performance before re-modelling was neglected. However, when initial performance was taken into account, re-modelling revealed significant, although varying effects on farrowing rate. [ABSTRACT FROM AUTHOR]

Contents The objective of this study was to evaluate the effect of short or long day light regimes on the reproductive performance in the sow. The study comprised approximately 1300 sows and their 3400 breedings in three commercial sow pools, in which a batch farrowing of 40 sows was employed. Each batch remained in the farrowing unit for 8 weeks under either a short day (10 h light, 14 h dark) or a long day (14 h light, 10 h dark) light regime. After weaning and transportation to the central unit, all sows were kept under the long day regime until they were moved back to the farrowing unit. Production results for each individual sow were recorded. The effect of the two different light regimes on the farrowing rate (FR) and on the weaning-to-oestrous interval was evaluated using logistic and Poisson regression models, respectively. The light regime affected none of the parameters significantly. The FR in June, July and August did, however, drop below that in December, January and February (OR 0.7, p < 0.05). The FR was affected by the sow pool (p < 0.01). Parity two sows exhibited a lower FR (OR 0.5, p = 0.05) and higher incidence of delayed first oestrus (IRR 2.7, p < 0.01) than did older sows. This study indicates that despite an artificial light regime, sows may still react to changes in season. In conclusion, use of simple light regime to obtain complete control over reproductive performance appears to be difficult. [ABSTRACT FROM AUTHOR]

PREGNANCY ,PROGESTERONE ,FERTILITY ,ANIMAL welfare ,SOWS - Abstract
Contents From 1.1.2013 EU legislation will permit stall-housing of dry sows for only 4 weeks post-service. Stalls are associated with compromised animal welfare, but group housing comes with risks from social confrontations. Studies on housing effects on fertility have produced contradictory results as systems are inconsistently defined. Effects of housing on pregnancy rate 28 days post-service (P28), early disruption of pregnancy (EDP) and behaviour were investigated in 12 replicates of 40 sows. Half of the animals were stalled (treatment S, mean parity 2.4) and half group-housed adjacent on 5.1 m
2 deep litter per sow (treatment G, mean parity 2.3). Pregnancy was detected using real-time ultrasound. An EDP-diagnosis required a drop of salivary progesterone concentration from >15.9 to <15.9 mmol/l in a series of samples taken on days 17, 20, 24 and 27 post-service. Behaviour was scan sampled on day 27 for 120 min with 10-min intervals. Data was analysed using mixed regression models in MLwiN. Treatment S increased the odds for P28 with 2.3 and the pregnancy rate of a treatment group with 0.1 compared with G. G increased the odds for EDP with 4.6. Treatment did not affect total exploratory or total passive behaviour. S sows explored floor and fixtures (not bedding) more and performed more passive sitting than G sows. Social stress may have caused the impaired reproductive performance in G sows. S sows showed behavioural signs of decreased welfare, but no corresponding reproductive effects. An interdisciplinary approach is needed when evaluating the appropriateness of housing systems. [ABSTRACT FROM AUTHOR]- Published

Orexin A (OXA) and orexin B were originally isolated as hypothalamic peptides regulating sleep, wakefulness and feeding. However, growing evidence suggests that orexins have major functions also in the peripheral tissues. Central orexigenic pathways originating from medulla activate the hypothalamus–pituitary axis and can influence the sympathetic tone. Orexins and their receptors are widely dispersed throughout the intestine, where orexin receptors are regulated by the nutritional status, affect insulin secretion and intestinal motility. Although the primary source of the peptide has not been elucidated, OXA is detected in plasma and its level varies in response to the metabolic state. In this review, we focus on the current knowledge on peripheral functions of orexins and discuss possible endocrine, paracrine and neurocrine roles. [ABSTRACT FROM AUTHOR]

Contents A total of 21 sow herds were randomly chosen to determine the prevalence of vulvar discharge syndrome (VDS) in loosely housed sows. The median VDS prevalence was low as expected, 0% (range 0–4.5%). Nine of the 655 animals examined (1.4%, 95% CI 0.5–2.3) displayed signs of VDS in 21 non-problem herds. In addition, five VDS problem farms were visited to gather more animals affected with the syndrome in order to estimate which methods of examination are useful. Altogether, 19 VDS animals and 19 healthy controls were found, inspected and sampled. Ten of the VDS animals (53%) and three of the controls (16%) were positive in bacterial culture (p = 0.04) taken with a guarded swab from the anterior vagina. In addition, 94% of VDS animals had a positive vaginoscopic examination result and the corresponding figure in the control sows was 28% (p < 0.0002). Cytological smears were classified as positive in 37% of the case sows and in 5% of the control sows (p = 0.04). Detection of vulvar discharge was associated with vaginoscopic examination findings (p = 0.0005) and with bacteriology (p = 0.04), but not with leucocyte counts (p = 0.07). Susceptibility testing was performed on pure bacterial cultures. Totally, 7 (44%) of 16 isolates were considered to be resistant or showed intermediate susceptibility to at least one of the antimicrobial agents tested (sulpha-trimethoprim and ampicillin). In conclusion, we found vaginoscopy and bacteriology as valid tools in diagnosis of VDS and susceptibility testing of antimicrobial treatments was found to be indicated. [ABSTRACT FROM AUTHOR]

Data were collected on the housing, management and disease factors in the weaning and finishing units of 49 integrated pig herds, 24 of them with a high incidence of arthritis at slaughter (case herds) and 25 with a low incidence (control herds). A median of 5·2 per cent (range 3·7 to 12·4 per cent) of the slaughtered pigs in the case herds had arthritis at meat inspection, compared with 2·2 per cent (range 0·3 to 2·8 per cent) in the control herds. In the farrowing units, high clinical sign scores for the lactating sows and piglets less than one week old and a low age at castration were associated with the case herds. In the weaning units, the herds with open partitions between the pens were 5·6 times more likely to be a case herd than the herds with solid walls. A higher age at weaning and moving the piglets at weaning from the farrowing pen instead of the sows decreased the likelihood of being a case herd. In the finishing units, a higher score for clinical signs, using a proper hospital pen, disinfecting the pens between the groups and using a feeding plan increased the likelihood of being a case herd. In total, 145 condemned joints, a median of four (up to six per herd), were collected at the slaughterhouse. In the case herds, 71 of 76 joints (93·4 per cent) had lesions related to osteochondrosis and in the control herds 66 of 69 joints (95·6 per cent) had such lesions. Only two of 11 joints from the case herds and one of 12 joints from the control herds that were examined bacteriologically were positive for Stopylococcus aureus and/or Streptococcus species.

Contents The effect of vulvar discharge syndrome (VDS) on sow and gilt fertility was studied on 26 farms. Of 824 animals inspected in 21 randomly selected and five VDS problem farms, 19 (2.3%) were afflicted with VDS. Altogether 542/799 of the examined animals (67.8%) farrowed thereafter. Nine of the 19 VDS animals (47.4%) and 533/780 non-VDS animals (68.3%) farrowed at the first chance after the examination (p = 0.05). None of the unmated gilts in this study had VDS. Environmental and individual factors likely to be associated with fertility and VDS were tested. In multivariate analysis, factors associated with farrowing were VDS, reproductive status, availability of roughage and confinement to individual stalls. None of the variables tested was associated with VDS. However, all of the VDS problem farms were overcrowded and had concrete, partly slatted floors with little or no bedding. The median value of haptoglobin (Hp) was 2.5 (range 1.3–3.1) g/l in VDS animals and 2.3 (0.5–4.3) g/l in controls (p = 0.6). The median C-reactive protein (CRP) in VDS animals was 30.3 (3.3–171.3) mg/l and in controls 25.9 (3.3–361.1) mg/l (p = 0.7). In conclusion, VDS decreased fertility of gilts and sows in the absence of a systemic acute-phase response, as indicated by stable concentrations of Hp and CRP. [ABSTRACT FROM AUTHOR]

Contents To study the relationship between on-farm welfare and reproductive performance in the sow, the TGI 35L Animal Needs Index was modified for use in Finnish pig production. The modified index had a maximal total score of 100. It was comprised of six categories: ‘locomotion’ (maximal score 21 for dry sows and 11 for lactating sows), ‘social interaction’ (12/8), ‘floor quality’ (16/9), ‘stable climate’ (16/21), ‘feeding’ (16/23) and ‘health and stockmanship’ (19/29). Index scorings were performed separately in farrowing, breeding and gestation units on 28 representative Finnish sow farms. One-year production parameters were collected. Multiple linear regression was used for statistical analysis. Total ANI-points varied between 36.5–68.0 for lactating and 39.5–86.0 for dry sows. Litter size increased with increasing scores for ‘feeding’ in the dry sow unit. Controlling for breed, high scores for ‘health and stockmanship’ and ‘floor quality’ shortened the reproductive cycle, probably because of good leg health. The number of weaned piglets per sow per year (PSY) increased with increasing scores for dry sow ‘health and stockmanship’, ‘floor quality’ and an interaction of ‘feeding’ in the farrowing and mating units. PSY increased with decreasing scores for farrowing pen ‘climate’. High-quality floors and stockmanship appear to correlate positively with reproductive performance in the sow. Effects of a welfare-promoting feeding strategy on reproduction are contradictory. [ABSTRACT FROM AUTHOR]

The prevalence of lameness among 646 sows and guts in 21 selected herds was determined; 8-8 per cent of the animals were lame and the most common clinical diagnoses were osteochondrosis, infected skin lesions and claw lesions. The lame animals had higher serum concentrations of haptoglobin and C-reactive protein than the sound animals. Animals housed on slatted floors had twice the odds of being lame and 3.7 times the odds of being severely lame than animals housed on solid floors. Yorkshire pigs had 2.7 times the odds of being lame than Landrace or crossbred animals. Higher parity and the use of roughage decreased the odds of the sows not becoming pregnant; however, lameness was not a risk factor for non-pregnancy. [ABSTRACT FROM AUTHOR]

This study was conducted to determine whether the seasonal delay in puberty in autumn is driven by individual differences in night-time melatonin secretion in domestic gilts at the attainment of puberty. A group of spring-born gilts (n = 30) were expected to reach puberty in autumn by the age of 7 months. Eighteen of these gilts were selected in pairs on the basis of matched days of birth. By the expected time, half of the animals showed oestrous symptoms (group CYCLING, n = 9) with the rest remaining silent (group SILENT, n = 9). Afterwards, all gilts were fitted with indwelling jugular catheters for frequent blood sampling. Blood samples were collected from all animals three times during the day followed by three times in the night at 2-h intervals for 48 h. The samples were analysed by a commercial radioimmunoassay (RIA). The results show a consistent 25-fold rise (on average) in night-time melatonin concentration in every animal sampled with group averages ranging from 0.28 ± 0.04 to 0.37 ± 0.06 pg/ml at day and from 10.20 ± 2.16 to 10.67 ± 0.05 pg/ml at night. Night-time group mean values between CYCLING and SILENT gilts did notdiffer significantly (10.26 ± 0.67 and 10.38 ± 0.94 for the CYCLING; 10.67 ± 0.05 and 10.20 ± 2.16 for the SILENT). When 10 pg/ml was used as a threshold value, six individuals did not reach it during the night (low responders). Two of these gilts were CYCLING and four were SILENT. In conclusion, the results presented imply no involvement of the level of night-time melatonin concentration in the seasonal delay of puberty in gilts. [ABSTRACT FROM AUTHOR]

EFFECT of light on reproduction ,DOMESTIC animal reproduction ,SOWS ,ANIMAL culture ,ANIMAL breeding ,VETERINARY medicine - Abstract
Two artificial lighting regimens were studied in a commercial unit of 800 sows. The aim was to develop a simplified lighting regimen to overdrive the effects of season on reproduction. A long-day group had a constant 16 hours light and eight hours dark photoperiod in all units during a production cycle. A short-day group had eight hours of light and 16 hours darkness in a farrowing unit for four weeks and in a mating unit for four weeks. After one month of pregnancy the short-day group was transferred to 16 hours light and eight hours dark for the rest of the dry-sow period. Production data were collected for eight months, and the farrowing rate, weaning to oestrus interval, culling rate for fertility problems and the number of live-born piglets were analysed. Seasonal infertility, which had previously affected the herd, was not detected in either group during the follow-up period. The farrowing rate was 90 per cent for both groups. The median weaning to oestrus interval was five days in both lighting regimens with ranges from four to 74 days in the short-day group and three to 55 days in the long-day group. The long-day programme had a positive effect on the weaning to oestrus interval. When the sows were classified as either ‘normal’ with a weaning to oestrus interval of up to 10 days, or ‘problem’ animals, with a weaning to oestrus interval of over 10 days, the short-day programme also had a positive effect. The culling rate for fertility problems was 2.4 per cent for the short-day group and 3.2 per cent for the long-day group (P=0.027). The only significant predictor for the number of live-born piglets was parity (P=0.027). [ABSTRACT FROM AUTHOR]

Porcine parvovirus (PPV) is widespread among swine. Our objective was to determine the prevalence of loosely housed sow herds in Finland with at least one animal with high (infection level) PPV antibodies and to gather basic knowledge about vaccination practices. In addition, selected factors associated with high antibody levels found in sows were examined. Altogether, 247 animals were sampled in 21 randomly chosen loosely housed sow herds. Samples were analysed with the haemagglutination inhibition (HI) test. PPV proved to be common; in 17 farms (81%) at least one animal had a high titre (>1 : 512), and 44% of all animals sampled had a high titre. The vaccination programmes had many shortcomings. In the generalised estimation equations (GEE)population-averaged model developed, the factors found to have a significant (p ≤ 0.05) effect on HI titres were herd size, parity of two or greater and storage of the vaccine vial after use. Non-returning rate, re-breeding interval and litter size did not differ between herds with no high HI titres (n = 4) and those with at least one high HI titre (n = 17). [ABSTRACT FROM AUTHOR]

- Abstract
Faeces samples were taken three times at two-week intervals, from the farrowing units of four herds of known (formerly ) status and one of unknown status. and group III were isolated from the faecal samples from the weaners in the herds using either a maximum of 50 ppm of olaquindox or no feed additives. The detection rates were relatively consistent. However, was not detected at one sampling in a known positive herd. The prevalence of species was also studied in feeder pigs originating from LSO 2000 health class farrowing units, comparable with specific pathogen-free herds. These farms were free from swine dysentery, sarcoptic mange, swine enzootic pneumonia and progressive atrophic rhinitis. Fifty of 428 herds were sampled once. was not isolated from any of them, but and group III were isolated from five, 14 and 37 of the herds, respectively. The detection of species did not relate to the prevalence of diarrhoea in the herds, as judged by the farmers. The herds using carbadox (40 to 50 ppm) had a lower prevalence of species than those using olaquindox (40 to 50 ppm). [ABSTRACT FROM PUBLISHER]

Contents This study was conducted to determine the antibody response for porcine parvovirus (PPV) of 39 gilts in field conditions after vaccination. Gilts from four herds endemically infected with PPV were injected twice with a commercial vaccine of inactivated PPV and Erysipelothrix rhusiopathiae. The PPV antibodies were analysed both with haemagglutination inhibition (HI) and enzyme-linked immunosorbent assay (ELISA) in order to study the agreement between these methods. The possible association between high-antibody titres and reproductive failure (repeat breeding, culling for infertility, ≤6 piglets born alive) was also investigated. In these study herds, endemically infected by PPV, most gilts (84.6%) had not seroconverted by the age of 6 months. On-field vaccination resulted in a consistent increase of humoral immunity not exceeding the antibody level of 1 : 512 in the majority of gilts in all herds examined. The agreement between ELISA and HI tests was moderate (Spearman's ρ = 0.87, κ = 0.63). The seroconversion over the level >1 : 512 by mid-pregnancy was not associated with reproductive failure.
