Research progress on application of dry white liquor distiller's grains in ruminant animal production

中文摘要英文摘要

随着畜牧业的发展,我国畜禽养殖数量逐渐增加,因此带来动物饲料资源短缺的问题.为解决这一问题,开发非常规饲料成为发展畜牧生产的关键.我国是白酒酿造大国,每年产出大量白酒糟残余物.干白酒糟作为一种白酒酿造残余物,具有较高的消化率,含有丰富的可溶性糖、蛋白质等物质,这些营养物质有助于提高饲料的适口性,促进消化液的分泌,易被动物机体吸收,从而有助于动物机体的生长发育.干白酒糟能够调节肠道菌群结构,改变反刍动物瘤胃的内环境.因干白酒糟来源广泛、价格低廉,可以替代部分饲料原料,有利于降低饲养成本.文章在分析干白酒糟营养价值的基础上,进一步对干白酒糟饲料化加工技术、饲喂方式、在反刍动物生产中的应用及干白酒糟饲料化利用的限制因素进行综述,以期为干白酒糟在饲料生产中的应用提供参考.

With the development of the livestock industry,the number of livestock and poultry in China is increasing gradually,leading to a shortage of animal feed resources.To address this issue,the development of unconventional feed as a substitute for feed has become key to the development of livestock production.China is a big country of liquor brewing,which produces a large amount of liquor residue every year.Dry white liquor distiller's grains,one of the waste products,has a high digestibility and is rich in soluble sugars,proteins,and other substances.These nutrients can improve the palatability of feed,promote the secretion of digestive fluids,and are easily absorbed by the animal body,thereby aiding in the growth and development of the animal.Dry white liquor distiller's grains can regulate the structure of the intestinal flora and alter the internal environment of the rumen in ruminant animals.Due to its widespread availability and low cost,it can replace some feed ingredients,which is beneficial for reducing the cost of breeding.Based on the analysis of the nutritional value of dry white liquor distiller's grains,the feed processing technology,feeding methods,application in ruminant production and the limiting factors of feed utilization of dry white liquor distiller's grains,were further reviewed in this paper,in order to provide reference for the application of white liquor distiller's grains in feed production.
