Research Interests 

Research interests deal with nitrogen/protein metabolism of ruminant livestock fed forages. Of special interest is nutritional manipulation of endogenous nitrogen recycling in the ruminant, with the following research objectives: 1) how ruminal protein degradability and supplementation frequency impact the recycling process, 2) expression and distribution of urea transporters in the rumen and other tissues involved in the recycling process, and 3) how nutritional manipulation of recycling influences visceral organ mass and subsequent efficiency of protein and energy use by the animal.
