发酵豆粕在犊牛饲料中的应用进展

豆粕是一种优质的植物性蛋白来源,含有丰富的氨基酸,但也含有胰蛋白酶抑制因子、抗原蛋白以及大豆凝集素等抗营养因子,容易引起犊牛消化功能紊乱,造成营养性腹泻,限制了其在犊牛上的使用量。微生物发酵可以改善豆粕的营养价值,使抗营养因子得到充分的降解,生成的小肽和有机酸有利于犊牛消化吸收和肠道健康,进而提高犊牛断奶日增重和免疫能力,降低犊牛的腹泻率和断奶应激。本文综述了豆粕经过发酵后带来营养价值的变化,并就发酵豆粕在犊牛上的应用进行概述,为其今后在犊牛中的应用提供参考。

Advances in Application of Fermented Soybean Meal in Calves Feed

Soybean meal is a high-quality plant protein,rich in amino acids,but it contains antinutritional factors such as protease inhibitors,antigen protein and lectin,which is easy to cause the disorder of digestive function of young animals,cause nutritional diarrhea,and limit the use of young animals. Microbial fermentation can improve the nutritional value of soybean meal and fully degrade anti nutritional factors. The generated small peptides and organic acids are conducive to animal digestion and absorption and intestinal health,so as to improve the daily weight gain and immune ability of calves,and reduce the diarrhea rate and weaning stress of calves. This paper summarizes the changes of nutritional value of soybean meal after fermentation,and summarizes the application of fermented soybean meal in calves,so as to provide reference for its application in calves in the future.
