摘要
分别从饲用酶制剂对畜禽日粮中抗营养因子、消化道内源酶活、微生物菌群、消化器官、外周血液激素水平以及畜禽机体免疫机能等方面的影响 ,对其改善畜禽生产性能的作用机制进行了探讨。饲用酶主要是通过消除抗营养因子(SNSP、消化酶抑制剂、细胞壁和植酸 )和补充内源酶等方式提高日粮养分消化率 ,并减少有害微生物的过度繁殖 。
The mechanism of feed enzymes improving animal performance was discussed in this paper according to the effects of feed enzymes on antinutritional factors, endogenous enzyme activities, micro organism of digestive tract, digestive organs, hormone level in plasma and the immune system of animal. The feed enzymes improve animal performance mainly through degrading antinutritional factors(SNSP, endogenous enzyme inhibitors, cell wall and phytate), compromising digestive enzyme in young animal gastrointestinal tract. The nutrients availability were increased and the flora overly fermenting decreased in hinder digestive tract at the same time.
