Evaluation of a Prototype Air-Filtered Transport Trailer
In response to the need by the industry for a livestock vehicle that addresses increased animal welfare and biosecurity during transport, a prototype air-filtered trailer was developed. Design parameters were gathered from a stakeholders’ survey and initial design configuration options were narrowed down using computer simulation. The...
Interaction of Dietary Fibre and Immune Challenge on Threonine Requirements and Pig Robustness
Sub-clinical disease results in reduced growth and less efficient use of nutrients. With the elimination of in-feed antibiotics for growth promotion it is increasingly important to understand the interaction between nutrition and health and nutrient requirements during disease challenge events. This project set out to more...
Development of a Commercial Scale Air Treatment System
An air cleaning technology based on biotrickling filtration developed in previous phases of the project was scaled up and tested at the PSC swine grower-finisher facility. Results showed that the air treatment units were effective in reducing the levels of ammonia, dust, and odour...
Creep Feeding in the Farrowing Room: Do the Outcomes Depend on Weaning Age?
Creep feed could benefit older weaned piglets by supplementing nutrients in sows’ milk. Additionally, it could aid the transition to solid feed at weaning, perhaps more of a benefit to the younger weaned piglet. In our experiment, body weight at nursery exit was greater...
Practical Environmental Enrichment Strategies for Piglets
Pigs are intelligent and curious from birth, and the lactation and nursery periods are critical for their mental and physical development. Despite this, research on suitable enrichments for piglets is lacking. Research that has been done found that piglets given enrichment had...
Assessing Particle Size and the Cost of Grinding
Particle size reduction improves feed efficiency in all stages of the production cycle in pigs. Based on studies by researchers at Kansas State University (KSU), an average particle size of 700 to 800 microns (um) is recommended. However, this recommendation is based on studies conducted using...
Reducing Water Consumption in Swine Barns: Alternatives for Animal Drinking and Barn Cleaning
Evaluation of selected water conservation measures involving drinkers and different cleaning procedures revealed that 60% reduction in water wastage was achieved with a drinking trough (with side panel and constant water level) to nipple drinkers. The use of conventional nozzle...
Temperatures Within a Truck Transporting Pigs During Winter and Summer Months in Western Canada
Transportation, which is an unfamiliar to the pig – is one of the most critical periods in pig handling before slaughter. It possibly involves economic losses due to deaths, ‘suspect’ animals on arrival at the processing plant, and reduced meat quality. Losses are...
Can Trailer Design Effectively Reduce Disease Transmission?
In response to an industry need for a livestock vehicle that addresses both increased animal welfare and biosecurity during transport, a prototype air-filtered trailer was designed and assembled. The project set out to select the best possible option for a...
Interaction of Dietary Energy and Phytase on Performance of Weanling Pigs
Approximately 60 to 80% of the phosphorus (P) in cereal grains and oil seeds is bound to phytate and unavailable to monograstics, including swine. Supplementing swine diets with the phytase enzyme improves P availability and retention. The phytate molecule complexes other minerals, proteins, and...
Impact of Prod Use on Highly Stressed Pigs
Pigs were subjected to three different handling treatments as we moved them through a 300m handling course. Despite traveling the same distance as the others, pigs moved at a moderate pace with only a board, quiet voice and gentle slaps, were essentially unstressed by...
Engineering Controls Reduce Hydrogen Sulphide Exposure in Swine Barns
Three engineering control measures were developed and tested for effectiveness in protecting swine barn workers from exposure to hydrogen sulfide (H2S) gas during manure handling events. A remote manure pit plug pulling system allowed the worker to pull the manure pit plug from outside the...
