在所有氮源中，Phe无论对混合瘤胃微生物还是对4株纤维素降解细菌均具有明显的促进纤维素降解的作用，但作用机制不同。

Phe increases the degradative rate for cellulose of both the mixed rumen microbes and the 4 strains of cellulolytic bacteria , but the effects of Phe on the growth of bacteria are different with strains .

提高日粮蛋白水平不改变微生物总EAA比例（P＞0.05），但改变瘤胃微生物氨基酸组成（P＜0.01），EAA中是精氨酸、组氨酸、亮氨酸、蛋氨酸、苯丙氨酸和苏氨酸的比例。

Increasing dietary protein levels resulted in similar ( P0.05 ) ratio of total EAA or non-essential AA to total AA of microbial proteins , but in changed microbial individual AA proportions ( P0.01 ), including those EAA of arginine , histidine , leucine , methionine , phenylalanine and threonine .

同时，高精料日粮造成瘤胃微生物稳态失衡，瘤胃内革兰氏阴性菌释放大量的细菌内毒素（LPS），引起瘤胃液和粪中的LPS含量升高。
