Evaluating the effects of mitigation strategies on piglet welfare and future productivity after transport during different seasons
As consumer concern for swine welfare, husbandry methods, and antibiotic use in animal agriculture increase, so will the need for U.S. pork producers to demonstrate that current production practices not only increase animal performance, but also improve the overall health…
Broadly protective nasal mucosal vaccine for influenza A virus of swine
Influenza A virus of swine (IAV-S) is widespread and causes significant losses to swine producers. Besides its economic burden, the virus also poses a great threat to public health due to its zoonotic potential. Therefore, successful control of IAV-S will…
Evaluation of Transportation Conditions on Performance of Weaned and Feeder Pigs
Transportation of pigs at early ages may result in profit-stripping incidence of mortality and compromised animal welfare due to stress stemming from unfavorable transporting conditions. This project took a four pronged approach to address possible causative relationships of mortality rate,…
Optimized Minimal Floor-space for Group-Pen System Using Feeding Stalls and Diet Strategy to Improve Well Being
Sow aggression is a common problem associated with group-housing systems especially during feeding and mixing of sows. Grouped-housed sows establish a social hierarchy upon mixing which often reduces aggressive encounters later-on, however pregnant sows often still engage in aggressive encounters…

Weaning sows directly into group housing: Effects on aggression, physiology and productivity
In the management of group housed sows, keeping sows in stalls from weaning until five weeks after breeding is a common strategy that serves to prevent aggression, control individual feed intake and facilitate management during breeding. However, pressure to reduce…
Development of a practical, cost-effective pain mitigation technique for castration of piglets
There is a growing trend towards the development of “welfare-friendly” management practices in production animals. Castration of piglets has gained considerable attention and there is growing pressure on the pork industry to develop management practices that address the pain associated…
