Effects of a temporary period on pasture on the transcriptomic signature of horses housed in individual boxes.

ABSTRACT: Over the past two decades, improving horse welfare through better housing conditions has emerged as a major concern. Different studies suggest that group living on pasture supports a higher welfare state compared with individual stabling. However, it remains unclear whether short-term access to pasture confers similar benefits for horses that are normally housed alone. To address this question, we monitored a population of horses accustomed to year-round individual stabling before and after a 1.5-month period on pasture, and compared them with a control group of individually housed horses that remained in their boxes. Blood transcriptome analyses were conducted to complete the behavioural assessments. Our results showed that acces to pasture didn’t have the same effet on the different behavioural indicators and that aggressiveness toward humans was the behavioural trait most strongly correlated with alterations in blood gene expression. The associated molecular pathways were predominantly linked to systemic inflammatory processes.

Transcriptomic signature related to welfare of horses housed in individual boxes

Project description:In this new study, we analyzed the blood transcriptome of horses housed individually that were first examined for their behavior, health and microbiota. We performed differential and regression analyzes of gene expression to unveil the molecular pathways related to the behavioural changes associated with housing horses in individual boxes. This study shows that aggressiveness towards humans and stereotypies are behavioural indicators that covary with physiological alterations.

Metabolomic signatures discriminate horses with clinical signs of atypical myopathy from healthy co-grazing horses

Project description:Atypical myopathy (AM) is a severe rhabdomyolysis syndrome that occurs in grazing horses. Despite the presence of toxins in their blood, all horses from the same pasture are not prone to display clinical signs of AM. The objective of this study was to compare the blood metabolomic profiles of horses with AM clinical signs with those of healthy co-grazing (Co-G) horses. To do so, plasma samples from 5 AM horses and 11 Co-G horses were investigated using untargeted metabolomics. Metabolomic data were evaluated using unsupervised, supervised, and pathway analyses. Unsupervised principal component analysis performed with all detected features separated AM and healthy Co-G horses. Supervised analyses had identified 1276 features showing differential expression between both groups. Among them, 46 metabolites, belonging predominantly to the fatty acid, fatty ester, and amino acid chemical classes, were identified by standard comparison. Fatty acids, unsaturated fatty acids, organic dicarboxylic acids, and fatty esters were detected with higher intensities in AM horses in link with the toxins' pathological mechanism. The main relevant pathways were lipid metabolism; valine, leucine, and isoleucine metabolism; and glycine metabolism. This study revealed characteristic metabolite changes in the plasma of clinically affected horses, which might ultimately help scientists and field veterinarians to detect and manage AM. The raw data of metabolomics are available in the MetaboLights database with the access number MTBLS2579.

Comparative gene expression profiling of group-housed, less aggressive vs. single-housed, more aggressive male flies

Project description:Social experience influences multiple behaviors of many animal species, including aggression. Social isolation often increases aggressiveness. To investigater the molecular basis of social influences on aggressiveness, we performed comparative gene expression profiling on heads from 6-day-old, single-housed, more aggressive and group-housed, less aggressive male flies. Keywords: social experience

Frequency and nature of health issues among horses housed in an active open barn compared to single boxes-A field study.

Project description:BackgroundKeeping horses in open barns has positive effects on social interaction and free movement, which may improve horse welfare. However, many horse owners fear that housing in open barns leads to more injuries.ObjectiveTo compare health events among horses housed in an active open barn (AOB) or in single boxes (BOX).Study designA prospective study during 9 months and a 2-year retrospective study.MethodsTwo housing systems in one farm were investigated: AOB and BOX in pairs or alone in paddock (2-4 h/day) using 66 and 69 horses in the prospective respectively retrospective study. Lameness, wounds, colic and days lost from training were recorded.ResultsThere were lower prevalences of lameness and colic in AOB than in BOX (18% vs. 26% and 0% vs. 5%; p < 0.001). Overall, there was a larger proportion of individuals with health events in AOB (83%) compared with BOX (52%) (p < 0.01). However, number of days lost to training did not differ between AOB (10 ± 15 days) and BOX (15 ± 34 days) (p = 0.36). There were no significant differences between the housing systems in number of health events/horse in the retrospective study: AOB 1.54 ± 1.51 versus BOX 1.14 ± 1.20 (p = 0.22).Main limitationsThe different, not standardised, housing systems varied in size and number of horses with no individual consideration in this descriptive field study with no possibility to cross-over. A convenience sample was used.ConclusionsLameness and colic were less frequent in the AOB system compared to single boxes, probably because the horses in the open barn could move freely day and night. Horses in AOB had a higher prevalence of wounds due to interactions between horses, but this did not lead to more days lost from training.

Gene Expression Analysis in the Thalamus and Cerebrum of Horses Experimentally Infected with West Nile Virus

Project description:The purpose of this experiment was to further our understanding of gene expression in the central nervous system (thalamus and cerebrum) after exposure to West Nile virus. To that end, three different analyses were performed. The first examined differences in gene expression between horses not vaccinated and exposed to WNV and normal control horses (exposure). The second examined differences in gene expression between horses not vaccinated and exposed to WNV and horses vaccinated and exposed to WNV (survival). And the third examined differences between the nonvaccinated cerebrum and nonvaccinated thalamus of horses exposed to WNV (location). Six conditions- Gene expression in the thalamus and cerebrum of three different groups of horses (Non-vaccinated horses exposed to West Nile virus, Vaccinated horses exposed to West Nile virus, normal horses not exposed to West Nile virus). Biological replicates- 6 normal cerebrums, 6 normal thalamus, 6 vaccinated and exposed cerebrums, 6 vaccinated and exposed thalamus, 6 non-vaccinated and exposed cerebrum, 6 non-vaccinated and exposed thalamus.
