The main goal of the Animal Nutrition and Feeding Laboratory is to improve ruminant feeding systems for viable and healthy production through elucidating the complex relationships between nutritional response and various dietary and physiological factors.

1) Kinetics of various amino acids and urea (Obitsu, T.)

2) Secretion and action of gastrointestinal hormones (Sugino, T.)
