Extract

It has been shown that rumen protozoa have a higher content of conjugated linoleic acid (CLA) and trans-vaccenic acid (TVA) than rumen bacteria, suggesting that protozoa may make a significant contribution to TVA and CLA flow from the rumen (Devillard et al., 2004). As part of a project studying the role of protozoa in rumen bio hydrogenation, this study was carried out to determine the effect of the absence of protozoa in the on ruminal biohydrogenation, microbial diversity and the fatty acid composition of lamb muscle.
