This study investigated if early life management practices influence the stress of pigs and whether this is detectable by measuring cortisol, dehydroepiandrosterone (DHEA) and the cortisol:DHEA ratio in swine hair. There was no effect of early life management on hair hormones. Piglets with pre-weaning lameness exhibited a 58% higher cortisol:DHEA ratio, suggesting this may be a potential biomarker of lameness induced stress.

Les bioaérosols des élevages porcins peuvent transporter des bactéries et gènes d’antibiorésistance (GAs). Ceux-ci ont donc été échantillonnés sur huit fermes au Québec. Les concentrations de bactéries étaient similaires entre l’intérieur des bâtiments et la sortie des ventilateurs. Les Clostridiaceae, Peptostreptococaceae et GRAs étaient majoritaires, suggérant une contribution de ces élevages à l’émission de bactéries et GRAs dans l’environnement.

Salmonella fait partie du microbiote digestif du porc et pourrait se retrouver dans ses produits de viande, causant des gastro-entérites chez le consommateur. Un probiotique testé dans un bioréacteur, mimant les conditions du colon du porc, a montré son efficacité dans l’inhibition du Salmonella dans cet environnement tout en modulant le microbiote intestinal du porc.

Research suggests that the hormones cortisol and dehydroepiandrosterone (DHEA) relate to stress and physical and mental wellbeing respectively and thus may serve as biomarkers of welfare in swine. The goal of this research is to determine if evaluating the circadian rhythms of these hormones as well as their concentrations within hair could serve as biomarkers of long-term welfare in swine

Exploring the possibility to promote play in grow-finish pigs to use it as a tool to promote positive welfare in intensive commercial systems as well as an indicator of good welfare on farms and identify whether play has positive effects on stress reduction and the emotional state of pigs.

The evaluation of animal welfare indicators on swine carcasses could offer a cost-effective method for the routine evaluation of swine welfare for farms supplying pigs to abattoirs. This project evaluates whether measuring animal-based indicators of welfare on swine carcasses can accurately inform about the welfare of swine on-farm and during pre-slaughter handling, and the relationship between welfare indicators, and economic loss.

PRRSv is infamously known for its impact on the worlds’ porcine industry. Since no efficient treatment is commercially available, this study evaluates the antiviral potential of four drugs derives from compounds which we have shown to inhibit PRRSv. Interestingly, two of these drugs, developed to treat HIV, have shown a significative decrease in viral replication in vitro.

English presentation. Pig microbiota, performance and genotype of eight cohorts from Ontario and Quebec were analyzed. Two enterotypes were identified when pigs were 11 days old that were associated with distinct microbiota composition. Pigs in one enterotype had better performance during pre-weaning and growing production stages. A 2-Mb span on Chromosome 13 contains twelve SNVs associated with these enterotypes.

This poster descriptively explores and identifies risk factors for increased mortality during weaned piglet transport events using records from over 6,000 trips provided by 5 Canadian production companies. The average percent of shipped piglets found dead on arrival for all trips was <0.03%. Mortality rates by trailer type, trip duration, exterior environment, and other variables are presented.

“Autogenous bacterin” vaccines offer an attractive solution to prevent the clinical cases caused by Streptococcus suis in pigs. We evaluated whether a polyvalent vaccine (containing several serotypes of S. suis) has the same efficacy as a monovalent formulation against a given serotype, and if the antibodies induced by these vaccines had cross-reactions between the serotypes.
