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