A kind of method for preparing liquor grains feed for feeding cattle and pigs

Abstract

The invention discloses a method for preparing a liquor mash fodder for feeding cattle and pigs, which belongs to the fields of a fodder technique, a microbial technique and livestock breeding and solves the problems of poor palatability and low effective energy when the liquor mash fodder is used for feeding the cattle and the pigs, the problem that only a small quantity of concentrates are replaced when the liquor mash fodder is directly used for feeding the cattle and the pigs and the problems that the price of an existing fodder is increased, the feeding cost is increased, and a novel fodder is lacked. The method comprises the steps: mixing liquor mash, whole grain brown rice and strains to uniformly, keeping the moisture of a mixture at 70wt% to 30wt%, and then bagging and sealing or storing in a cellar for anaerobic fermentation for more than 28 days or pH between 3.8 to 4.0 to obtain the product. The method has the advantages of simplicity in operation and easiness in industrialization, the liquor mash fodder can be directly fed after being opened or continuously sealed to be stored for a long time, and the quality is not influenced. The liquor mash fodder can be used as a unique concentrated complementary fodder for beeves, 50% of concentrated complementary fodder for high-productive dairy cows and 55% of concentrated fodder for breeding the pigs are replaced, the weight increasing / milk producing speed is greatly increased, and the fodder consumption for weight increasing / milk production in units is reduced.

Description

technical field [0001] The invention relates to the fields of feed technology, microbe technology and animal husbandry. Especially a method for preparing fresh distiller's grains for full utilization and direct feeding of cattle and pigs. Background technique [0002] Distiller's grains are the residues of sorghum, wheat, corn and other grains after solid-state fermentation and distillation to extract alcohol. According to statistics, my country's liquor brewing industry produces about 25 million tons of distiller's grains every year. Distiller's grains have high acidity and a moisture content of more than 65%, which is easily corrupted and difficult to store, and is likely to cause serious pollution to the environment; if the distiller's grains can be effectively and comprehensively utilized, it will not only solve the problem of environmental pollution, but also save food and reduce production. costs and obtain significant socio-economic benefits. Although there is a cu...

Problems solved by technology

It solves the problems of poor palatability and low effective energy when feeding distiller's grains to cattle and pigs, and can only replace a small amount of concentrated feed when directly feeding distiller's grains to avoid reducing the growth performance of cattle and pigs and raising the cost of breeding caused by the increase in the price of existing feed Increase and lack of new feed resources
