The Department of Animal Science originally concerned itself with teaching the selection, breeding, feeding and care of livestock. Today it continues this study of the symbiotic relationship between animals and humans, with practical focuses on agribusiness, science, and animal management.
History
The Department of Animal Husbandry was established in 1898. The name of the department was changed to the Department of Animal Science in 1962. The Department of Poultry Science was merged into the department in 1971.

Abstract
In the U.S., housing for the lactating sow and her piglets can be divided into five main areas. Total confinement (farrowing stall) houses 83.4 % of the sows. Remaining operations house far fewer sows with open buildings that have outside access at 12.4 %, open building with no outside access, 2.9 %, pasture with hut or no building, 0.7 %, and lot with hut or no building the lowest at 0.6 % [1]. Farrowing stalls have become widely accepted by the industry for numerous reasons: they have made sow management easier, efficiently utilized space, and they can help to reduce piglet mortality [2]. However, the farrowing stall has received criticism due to potential detrimental effects it may impose on the welfare of the sow (such as occurrence of shoulder ulcers [3, 4], behaviors considered problematic [5, 6, 7], and sow’s movements are more restricted). The development of an alternative, economical farrowing system that retains the advantages of the conventional farrowing stall, and provides welfare benefits to the sow and piglets, could be beneficial to the industry [8, 9].
