反刍动物过瘤胃蛋白的保护措施

The Protective Measurements of Rumen Bypass Protein in Ruminant

过瘤胃蛋白就是将一些蛋白质经过处理,避免在瘤胃内被发酵、降解,而直接进入小肠后再被消化吸收,从而达到提高饲料蛋白质利用率的目的。保护伺料蛋白免遭微生物过量降解,提高蛋白质的总体利用率的方法有许多,主要有物理方法、化学方法、生物学调控、瘤胃外流速度的调控、利用食管沟反射提高过瘤胃蛋白等。本文就目前蛋白质的各种过瘤胃保护途径和效果进行了综述。

Ruminally protected protein refers to some protein avoiding the degradation of protein in rumen through some protective measurements in order to make protein be digested and absorbed in small intestine to improve feed availability. To increase rumen bypass protein, there are many methods of protecting protein in feed, such as physical method, chemical method, biological manipulation, the regulation of digesta rate of flowing out of rumen and use of oesphageal groove reflex This review makes a summary for various protective ways of protein and their application results.
