Effects of gestation sow grouping practices on aggression and production
A concern with any type of group housing is the aggression performed when mixing unfamiliar sows into a group, as they compete to form a social hierarchy. Ongoing aggression is another related concern. It is important to understand how different...
Can slat-compatible enrichment influence the behaviour and response of pigs to a disease challenge?
Rearing pigs in highly enriched environments with a greater space allowance and provision of substrates (straw, mushroom compost, sawdust, wood branches) for rooting and chewing has been found to reduce the disease susceptibility of pigs to co-infection with PRRSv and...
Weaned piglet mortality during long transport events is affected by season
Limited information is available on factors associated with piglet mortality during weaner transport events. This study aimed to identify transport characteristics associated with the occurrence of in-transit mortality or increased rates of mortality (≥1 piglet found dead on arrival) using...
Weaned piglet transport practices in Canada
The objective of this study was to describe characteristics of weaned piglet transport events that occurred between 2014 and 2018 using records provided by five Canadian swine companies. The dataset included records from 6203 transport events involving the transport of...
Effects of transport duration on the health and welfare of early weaned pigs
Due to the physiological differences between weaned piglets and market hogs, additional data on their response to transport are needed for age-specific evidence-based recommendations. A cohort study was conducted to observe weaned piglets undergoing short duration (SD, <3 h), or...
Sow mortality in Canadian Swine Herds
Sow mortality is an area of increasing concern as production records indicate a significant increase in spontaneous death losses over the past 10-20 years. This project gathered information on sow mortality in Canadian herds through a literature review, a producer...
Effective piglet enrichment: effects on development and reduction of damaging behaviours
Tail biting is a behavioural problem that impacts pig welfare and the economics of pork production. Environmental enrichment can reduce damaging behaviours, but practical information on enrichments for young pigs is lacking. The project contained two studies to evaluate enrichment...
Investigating novel biomarkers of welfare in swine
Biomarkers are objective and quantifiable characteristics of biological processes. There are many measures taken to evaluate acute experiences that influence animal welfare, such as measurement of cortisol, a hormone that increases in acute stress after aggression. There is currently a...
Evaluating the impact of early life management of piglets on lifetime welfare and performance
The first 12 weeks of a pig’s life is a critical period of development, and what a pig experiences during this period of time will shape how an individual responds to subsequent life events, leading to consequences for the overall...
A new method for improving animal welfare oversight: routine monitoring of pig carcasses
Animal care verification requires the accurate evaluation and quantification of animal welfare. Assurance schemes typically rely on farm audits for animal care verification, which are time consuming, incur cost for the producer and can pose a biosecurity risk. One approach...
Can slat-compatible enrichment influence the behaviour and response of pigs to a disease challenge?
Rearing pigs in highly enriched environments with a greater space allowance and provision of substrates (straw, mushroom compost, sawdust, wood branches) for rooting and chewing has been found to reduce the disease susceptibility of pigs to co-infection with PRRSV and...
Play behaviour and its role to enhance pig welfare and production
This project is funded by the NSERC Industrial Research Chair program, a five-year research program focusing on emerging questions in swine welfare. Goal 2 will investigate whether play can be used as a tool to support positive welfare and beneficial...
