Course Description
Digestive physiology and metabolism of the rumen. Treats systematically the diversity of function, complex symbiotic relationships of the rumen microflora/microfauna, and the physiology and metabolism of the rumen as related to digestion, absorption, and utilization of nutrients.
Additional Requirements for Graduate Students:
Research a topic and prepare a written report.

Course Objectives
To develop an outline of- and supporting- information on the uniqueness of the RUMINANT in Animal Agriculture by: A. Presenting an in depth discussion on the development of the functional anatomy of the ruminant from the Neonate to the adult and a concise evaluation of the rumen microbes' contribution to Ruminant Nutrition and B. presenting and discussing the pertinent research on principles of Digestion, Site and Mechanisms of Nutrient Absorption, Post-absorption Nutrient Metabolism and Efficiency of Metabolite Utilization, Consequences on Nutrient Deficiencies in a manner such that each student will understand and be able to apply the material presented to Practical Ruminant feeding and production and feeding situations.
