The beneficial effects of polyphenol intake such as improved nitrogen retention make them interesting feed supplements for ruminants. In contrast, dietary polyphenols may have adverse on the bioavailability nutrients and palatability which might impair growth performance. differ between different ruminant species well direct metabolites via suckling when supplemented to lactating dams.

Consumers are increasingly becoming more aware of the relationships between diet and health. The functional–food components of beef and milk fat include ω–3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid (CLA). Beef typically has high saturated fatty acid content and low PUFA content, but the content of beneficial fatty acids can be increased by dietary manipulation. Dietary li...

In ruminants, dietary lipids are extensively hydrogenated by rumen micro-organisms, and the extent of this biohydrogenation is a major determinant of long-chain fatty acid profiles of animal products (milk, meat). This paper reports on the duodenal flows of C18 fatty acids and their absorption in the small intestine, using a meta-analysis of a database of 77 experiments (294 treatments). We est...

Development of Methodology and Characterization of Ruminal Lipase-Producing Bacteria In Vitro. (May 2011) Holly Danielle Edwards, B.S., Iowa State University Co-Chairs of Advisory Committee: Dr. Rhonda K. Miller Dr. T. Matthew Taylor Hydrolysis of dietary lipids to free fatty acids (FFA) is a prerequisite for ruminal biohydrogenation, a bacterially mediated process that extensively saturates un...
