Lab activities

Kate started a study on the effects of reducing the level of crude protein on performance and plasma urea nitrogen in weanling pigs. She also began a growth performance trial on pigs fed high lysine DDGS, and an ileal digestibility trial on pigs fed two types of threonine co-product and one valine co-product.

Neil finished lab work for a study on inclusion of direct fed microbials in diets fed to growing-finishing pigs.

Tanawong finished animal work on an experiment to determine phosphorus digestibility in canola meal.

Caroline started a study to determine values for apparent and standardized total tract digestibility of calcium in inorganic calcium sources.

Jessica started an experiment to compare DE and ME of feed ingredients in sows compared with growing pigs.


Dr. Stein traveled to Florida for a meeting of the NCCC-42 Swine Nutrition Committee.

Several members of the lab traveled for vacation over winter break. Tanawong went to Thailand, where he got married! Oscar went home to Colombia, and Diego returned to the Philippines for a visit. Meanwhile, back in the States, Shelby went home to California, Kelly went to Springfield, and Jen visited relatives in Arizona.
