发酵酒糟在养牛产业中的应用研究进展

Advances in the application of fermented distiller's grains in cattle industry

酒糟作为酿酒产业的副产物,近年在动物饲料中被广泛应用,其可替代日粮中的部分精料用于畜禽养殖,在一定程度上可缓解畜禽养殖业的饲料短缺问题。酒糟经过微生物发酵后能延长储存时间,而且能提高饲料中粗蛋白质含量及优化氨基酸组成,同时降低粗纤维含量,营养价值较高,提升了酒糟的饲用价值。本文主要对几种发酵酒糟特点、利用方式及发酵酒糟在养牛产业中的应用效果的研究进展进行综述,以期为发酵酒糟饲料化的研发与应用奠定基础。

As a by-product of wine industry,distiller's grains have been widely used in animal feed in recent years,which can partially replace concentrate in diet and alleviate feed shortage in breeding industry to some extent.The microbial fermentation of distiller's grains not only prolongs the storage time,improves the crude protein content,and optimizes the amino acid composition,but also reduces the crude fiber content in the feed,which has higher nutritional value and enhances the feeding value of distiller's grains.This paper mainly summarized the latest research progress of the characteristics,utilization methods and application effects of fermented distiller's grains in cattle industry,aimed to lay a foundation for the subsequent development and utilization of fermented distiller's grains as feed resources.
