Can hybrid rye replace wheat in swine diets?
Modern rye hybrids are less susceptible to ergot contamination than traditional rye, and has greater yield compared with wheat grain, which was a good incentive to evaluate feeding hybrid rye to grow-finish hogs. Rye is known to have greater fibre content than wheat grain, consisting...
Effectiveness of functional amino acids in Salmonella-challenged low and normal birth weight pigs
We wanted to determine the influence of birth weight (normal – NBW vs. low – LBW) on pig response to a subsequent disease challenge and on the effectiveness of functional amino acid (FAA) supplementation in ameliorating this response. Weanling piglets were fed one of two...
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 Actinobacillus pleuropneumoniae, increasing the speed...
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 production characteristics in pigs reared...
Animal protein-based nursery diets and functional amino acids improve performance and health status of weaned pigs
Nutrition strategies in the post-weaning period are geared towards providing high quality diets (i.e., inclusion of animal-based protein sources) to mitigate the effect of weaning stress and immature digestive and immune systems. Some studies suggest that the inclusion of animal-based protein sources may not be...
Assessing trailer cleanliness
A rapid, easy to use and reliable way of monitoring surface cleanliness of swine transport trailers is needed for practical industry applications. ATP bioluminescence has been demonstrated to be a good alternative tool for monitoring surface cleanliness in swine transport trailers, providing results within minutes...
Pigs consume more water when stressed
Two novel technologies consisting of an individual water consumption system (IWCS) and infrared thermography system (ITHS) were installed in a finishing room. The individual water consumption system (installed in each pen) was composed of a nipple drinker attached to a water flow meter, and an...
Effects of long distance transport on early-weaned pigs
While transporting weaner pigs is a common practice in swine production, there is very little published research on how this process impacts piglet health and welfare. To address this gap, Dr. Jennifer Brown and colleagues at the University of Guelph and University of Saskatchewan are...
Feeding canola meal or soy expeller at two feed energy levels to growout hogs
Previous research trials that we’ve conducted showed that we can feed reduced net energy (NE) diets (≤2.3 Mcal/kg) to growout hogs instead of traditional energy levels (≥2.4 Mcal/kg) as long as hogs can increase feed intake to compensate for reduced dietary energy level. Conventional (solvent-extracted)...
Design criteria for enhancing cleanability and welfare characteristics of pig transport trailers
Various aspects of trailer design and construction significantly impact the cleanability and welfare characteristics of the trailer, such as surface smoothness, exposed screws and weld joints, and presence of structures and hard-to-clean areas that may be prone to dirt accumulation. In this project, design criteria...
