RUMINANT NUTRITION. The major research goal is to manipulate ruminal fermentation to optimize animal productivity. To accomplish this goal, cell wall chemistry, associative effects of feedstuffs and ruminal microbiology are studied.

Specific Research Areas:
  • Manipulation of fermentation in the rumen to affect rate of digestion, rate of passage, bacterial protein synthesis and (or) methane production.
  • Nutritional effects on meat composition and palatability.
  • Chemistry of the cell wall of feedstuffs.
