Annual Report

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 from the air stream at...

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 starch, however, the research examining the...

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 the procedure. Pigs handled aggressively,...

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 room. A water sprinkling apparatus was...

The Interaction Between Pig Density and Dietary Energy on Performance

Dietary net energy and stocking density independently affect performance, feed utilization and profits in the finisher barn. The objective of this experiment was to assess the interactions of stocking density and dietary energy, and determine how these interactions affect net income. When stocking density was increased, the performance of finishing...
