反刍动物小肠氨基酸调控

反刍动物小肠氨基酸调控是反刍动物营养研究的重要课题。反刍动物小肠氨基酸的调控是以反刍动物氨基酸的需要为基础,有目的地通过各种途径使小肠吸收氨基酸含量达到动物的生产需要。反刍动物小肠氨基酸调控主要有以下几方面:通过瘤胃蛋白质保护、改变饲料在瘤胃中停留时间和添加生物制剂调节日粮过瘤胃蛋白质;通过日粮可发酵能、能氮平衡和瘤胃微生物环境控调微生物蛋白质;通过瘤胃保护氨基酸(RPAA)调控小肠氨基酸。

Modulation and Control of Small Intestine Amino acid in Ruminant

The principle and method of small intestine amino acid modulation and control in ruminant were reviewed on two aspects of ruminal bypass protein and microbial protein. There are three aspect in small intestine amino acid. Modulating ruminal bypass protein by protected diet protein, limited the time of diet pass by rumen and adding antibiotics is the one aspect. The another aspect is modulating and controlling microbial protein. The last aspect is modulating and controlling protected small intestine amino acid.;
