文摘

Feeding red clover silage modifies rumen fermentation and digestion in dairy cows. Feeding red clover increases the transfer efficiency of PUFA from diet to milk fat. Feeding red clover modified odd- and branched-chain fatty acid profile in milk. Feeding red clover decreased ruminal ammonia as well as plasma and milk urea. Varying rumen degradable protein supply had limited impact on rumen biohydrogenation.
