Targets and procedures for altering ruminant meat and milk lipids.
Beef and dairy products suffer from a negative health image, related to the nature of their lipid fraction. Rumen lipid metabolism involves the presence of saturated lipids in ruminant tissues. Lipolysis, fatty acid biohydrogenation and formation of microbial fatty acids in the rumen and their effects on rumen outflow of fatty acids are discussed. Special emphasis is given to the formation of t...

متن کاملGreat Basin Cattle Nutrition Research Programs: Strategies to Improve Nitrogen Utilization in Alfalfa Hay
The majority of ruminant livestock production occurs in temperate grasslands where animals are allowed to graze or are fed harvested forages (i.e., hays or silages). As a result, forages comprise 50 to 90% of total feed consumed by ruminants during their production cycle (Reid and Jung, 1982). In the U.S., beef cattle production is often viewed as an intensive enterprise because of finishing ca...

متن کاملUpdate on Bun and Mun as a Guide for Protein Supplementation in Cattle
At the 3rd Annual Ruminant Nutrition Symposium (Hammond, 1992), I reviewed the use of blood urea nitrogen (BUN) concentration for monitoring protein status in beef cattle, and discussed the potential for using milk urea nitrogen (MUN) as a noninvasive tool for monitoring protein status in dairy cattle. The purpose of this discussion is to review the basic concepts involved in urea nitrogen as a...
