摘要
半胱胺(CS)是一种在动物胃肠道和下丘脑产生的生物化合物,参与辅酶A和牛磺酸代谢。CS的巯基能与生长抑素特异性结合,间接地调节生长激素分泌,还可以作为细胞抗氧化剂。在反刍动物生产中,CS可以促进生长、缓解应激、增强抗氧化性能、减少瘤胃甲烷产生,是一种绿色安全高效的饲料添加剂。在绿色健康养殖的背景下,CS受到广泛关注。本文总结了CS的机体代谢途径、生理功能,阐述了CS对反刍动物主要生产性能的影响及应用前景。
Cysteamine(CS)is a biological compound produced in the gastrointestinal tract and hypothalamus of animals,which is involved in coenzyme A and taurine metabolism.The sulfhydryl group of CS can specifically bind to somatostatin,indirectly regulate the secretion of growth hormone,and can also act as a cellular antioxidant.In ruminant production,CS can promote animal growth,relieve stress,enhance antioxidant performance,and reduce rumen methane production.It is a green,safe and efficient ruminant feed additive.In the context of green and healthy breeding,the application of CS in ruminant production has received extensive attention.This paper summarized the metabolic pathways and physiological functions of CS,and combined with ruminant production,elaborated the influence of CS on the main production performance of ruminants and its application prospects.
