Preparation method of corn and soybean meal fermentation forage

Abstract

The invention discloses a preparation method of a corn and soybean meal fermentation forage. The method comprises the following steps: mixing raw materials comprising corn and soybean meal with water according to a corn-to-soybean meal-to-water ratio of 1:0.8-1:1.2, uniformly stirring, and disinfecting at 100-115DEG C; inoculating microbes having an amount accounting for 20-30% of the weight of the raw materials, uniformly stirring, and fermenting at 35-45DEG C for 48-60h; and carrying out low temperature drying. The moist heat sterilization and the microbe treatment enable antigen proteins, raffinose having a flatulence effect and stachyose having the flatulence effect in the forage raw materials to be effectively degraded, and a large amount of beneficial metabolites and beneficial microbes to be accumulated. The method has the advantages of easy control of the fermentation process, and stable quality of products obtained in the invention.

Description

technical field [0001] The invention belongs to the field of animal feed, and in particular relates to a preparation method of corn soybean meal fermented feed. Background technique [0002] Feed is the material basis of animal husbandry and is very important to animal husbandry production. The scale and development speed of animal husbandry production mainly depend on the amount of available feed. The quality of feed has a major impact on the quality of animal products. Its quality directly Affect the economic benefits of animal husbandry production. Chinese invention patent application No. 200610030846.5 discloses a method for preparing soybean meal with high lactic acid content and low soybean antigen by using soybean meal as raw material and using a solid-state fermentation process. The patent uses two mixed strains of Lactococcus and Saccharomyces cerevisiae for fermentation, and protease is added in the production process, which increases the production cost. In addit...
