Rumen fatty acid metabolism in lambs fed silages containing bioactive forage legumes
Résumé
Inclusion of forage legumes, such as red clover (RC) or sainfoin (SF), in grass silage might affect rumen lipid metabolism. Polyphenol oxidase (PPO) in RC is known to alter lipolysis, and tannins in SF modify biohydrogenation, which may subsequently modulate the fatty acid (FA) profile of ruminant-derived products. The aim is to investigate the possible additive effects of feeding PPO-containing RC and tannin-containing SF on the rumen FA metabolism.
