Research Activities

Research is focused on the interrelationships of feed milling, nutrition, and physiology on poultry performance; implementation of feed mill techniques that improve feed efficiency and reduce feed costs; identification of processing alternatives to decrease bacterial load in feed and feedstuffs; stability of feed additives during thermal processing, and use feed additives to improve broiler performance.

Extension Activities

Our extension program in feed milling supports the existing feed industry in the state by providing extension education in essential areas such as feed mill regulations, feed milling operations, ingredient and feed quality, feed safety as well as animal nutrition and serves as a catalytic agent to bring new ideas and innovation, which are essential for the future of the feed and poultry industry. Participation in fairs, FFA, and 4-H activities.
