New and alternative sanitization procedures for antibiotic-free swine barns
Certain barns that switched to antibiotic-free production observed increased prevalence of pathogens after a few years on the program. Developing improved sanitization and disinfection procedures is an important step to reduce the pathogen load in antibiotic-free barns, which was the...
Out of feed events and gastric ulcers in finishing pigs fed 40% pea-starch diets
Gastric ulcers in pigs are a concern for the industry. To be able to study gastric ulcer formation, an experimental model is required that will consistently result in gastric ulcers in pigs. The objectives of this pilot study were to...
The use of extrusion to reduce dietary ergot toxicity in growing pigs
Consumption of ergot alkaloids by livestock results in reduced feed intake and growth and a dramatic reduction in the hormone prolactin, which is important for milk production in sows. Previous research at the PSC demonstrated that extreme processing in the...
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...
Impact of antibiotic-free production on pathogen occurrence and prevalence of antimicrobial resistance
This study assessed the impact of Raised Without Antibiotics (RWA) production practices on on-farm antibiotic use, pathogen occurrence, and the prevalence of antimicrobial resistance genes (ARGs) through the whole genome sequencing and analyzing of samples (fecal, manure, sow nasal swab,...
Managing High Feed Costs
Feed costs always will be the single largest component in costs associated with pork production. Finding ways to effectively reduce feed costs while optimizing pig performance helps producers economic sustainability. This publication focuses on four key areas including: 1) Diet...
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 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...
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...
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...
