Abstract

A commercial blend of essential oil (EO) compounds was added to a grass, maize silage, and concentrate diet fed to dairy cattle in order to determine their influence on protein metabolism by ruminal microorganisms. EO inhibited (P < 0.05) the rate of deamination of amino acids. Pure-culture studies indicated that the species most sensitive to EO were ammonia-hyperproducing bacteria and anaerobic fungi.

摘要

将一种商业混合的精油(EO)化合物添加到用于喂养奶牛的牧草、玉米青贮饲料和精饲料中,以确定它们对瘤胃微生物蛋白质代谢的影响。精油抑制(P<0.05)了氨基酸的脱氨速率。纯培养研究表明,对精油最敏感的物种是氨高产细菌和厌氧真菌。
