{{`Trap-Neutering by gonadectomy-Return' (TNR) is currently becoming an accepted method for managing free-roaming cat (FRC) populations, especially in human habitation. However, data regarding its impact on cat welfare are limited. In order to determine the demographic risk factors for FRC morbidity, we followed FRC populations in the city of Rishon LeZion during 2012-2014. Their age status (kitten/adult), contraceptive status (neutered/intact), sex, body-condition-scoring (BCS 1-5/5; 1 = emaciation

In many countries sows are kept in individual stalls from insemination up to just few days prior to farrowing. The overall objective of this study was to examine group housing management system for sows during gestation as an alternative for individual confinement stalls, and the possible effects on their welfare, production and reproduction performances. Accordingly, the study included three specific objectives: (1) to compare parameters of production, reproduction, and welfare of sows housed in groups (either 30 or 7 sows/group; Large Group: LG, Small Group: SG, respectively) during gestation as compared to individual confinement stalls (IS); (2) to compare saliva cortisol of pregnant sows throughout gestation, when housed in groups of three different sizes (either 7, 15 or 30 sows per pen group); and (3) to compare sows' production and reproduction performances at the herd level, before, during and after practically transforming from a management of individual confinement stalls to a group housing system, in a large commercial swine farm over a six-year period. Mean cycle length (weaning-to-weaning) was shorter in group housing management as compared to individual stalls (P = 0.0110), but gestation length did not differ among the three groups. Overall farrowing rate (sows farrowed out of those inseminated) was higher (P ≤ 0.0134) for sows housed in groups (either SG or LG). Furthermore, there was a tendency towards a higher number of total born (P = 0.1033), and born alive piglets (P = 0.0862), in group housing system as compared to individual housing management; however, it did not differ between the LG and SG groups. Injuries and lameness index (ILI) of sows improved significantly over the gestation period in group housing management. Group saliva cortisol during gestation did not differ significantly among groups of 7, 15, or 30 sows, except on the first saliva sampling, just after sows were mixed into groups, where cortisol level was significantly higher in sows housed in a pen of 30 sows. Production and reproduction performances at the herd level, over a 6-years period- before, during and after transforming to a group housing system, improved significantly: shortened cycle length, increased farrowing rate, and increased number of total born and born alive piglets. In conclusion, group housing management during gestation was associated with better reproduction, productivity and welfare of sows, as compared to individual stalls. A welfare friendly housing system can be beneficial and effective for both the farmers and the animals.

Post-partum metritis is among the most prevalent disease in dairy cows affecting animal welfare and inflicting considerable economic loses. While post-partum contamination of the uterus is rife in dairy cows, only a fraction of these animals will develop metritis. Our main objective was to compare the bacterial communities and the inflammatory response in the endometrium of healthy and metritic dairy cows. Holstein-Friesian cows (n = 35) were sampled immediately following clinical classification as healthy (n = 21), suffering from metritis (n = 13) or septic metritis (n = 1), based on veterinary examination at 5-10 days post-partum. Polymorphonuclear cells (PMN) percentage in endometrial cytology was significantly higher in cows with metritis. Full-thickness uterine biopsy analysis revealed that the luminal epithelium in inter-caruncle areas was preserved in healthy cows, but in metritis it was compromised, with marked PMN infiltration particularly in the apical endometrium. Gram staining revealed that bacterial load and spatial distribution was associated with disease severity. 16S-rDNA bacterial community analysis revealed unique endometrial bacterial community composition in metritic cows, as compared to more diverse communities among healthy cows. The most abundant phyla in healthy cows were Proteobacteria (31.8 ± 9.3%), Firmicutes (27.9 ± 8.4%) and Bacteroidetes (19.7 ± 7.2%), while Bacteroidetes (60.3 ± 10.3%), Fusobacteria (13.4 ± 5.9%) and Firmicutes (10.5 ± 3.3%) were most abundant in the endometrial mucosa of metritic cows. Relative abundance of Bacteroidetes (19.7 ± 7.2% vs. 60.3 ± 10.3%), Fusobacteria (7.5 ± 5.2% vs. 13.4 ± 5.9%) and Proteobacteria (31.8 ± 9.3% vs. 7.3 ± 5.6%) phyla differed significantly between healthy and metritic cows. In summary, endometrial PMN abundance, spatial distribution and bacterial communities differed between healthy and metritic dairy cows at early post-partum.

The aim of this prospective study was to investigate possible endocrine components to foal rejection behaviour in post-partum Arabian mares. Arabian mares were divided into two groups based on their maternal behaviour: (1) mares with normal post-parturient behaviour (8 mares); and (2) mares that demonstrated foal-rejecting behaviour post-partum (15 mares). Most mares were visited and sampled twice, in the first and third days post-partum. Serum samples were used for measurement of progesterone, oestradiol and prolactin concentrations. There were no statistically significant differences in oestradiol, progesterone or prolactin concentrations between the groups. In the rejecting mares, there was a statistically significant decrease in the progesterone (mean±standard deviation, SD, 3.14±6.2ng/dL on day 1 and 0.49±0.18ng/dL on day 3) and prolactin (mean±SD 216.2±325.4ng/mL on day 1 and 145.2±311.4ng/mL on day 3) concentrations between days 1 and 3, while the oestradiol concentration did not change significantly. In the non-rejecting mares, progesterone concentrations decreased significantly (mean±SD 0.8±0.23ng/dL on day 1 and 0.43±0.22 on day 3) while the oestradiol and prolactin concentrations did not change significantly. The oestradiol to progesterone ratio was significantly higher in non-rejecting mares on day 1 (mean±SD 114.8±140.2 on day 1 and 143.4±72.6 on day 3) and this ratio increased significantly from days 1 to 3 in the rejecting mares (mean±SD 47.3±21.1 on day 1 and 122.1±123.7 on day 3).
