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, at a fast pace, with shouting and slapping, but without use of electric prods had a higher incidence of stress, but none showed extremes that might lead to animal losses. Use of the electric prod resulted in a large proportion of the pigs showing both behavioural and physiological signs of stress, with some being extreme to the point of stumbling and falling. We should minimize the use of the electric prod by changing our handling techniques and/or modifying our load out facilities.

Response of Growing-Finishing Pigs to Dietary Energy Concentration
In this trial, feeding lower energy, lower cost diets had no effect on ADG or on loin thickness, but did improve feed efficiency, and reduced backfat thickness. This indicates that lower energy diets may be used to increase net income. This experiment was conducted in an environment of high feed intake, and different results may accrue under conditions of lower…

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 effect of the phytase enzyme on the utilization of these…

Engineering Controls Reduce H2S 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 also devised, which resulted in 79% reduction of H2S gas concentration…
