Abstract

The invention discloses a method for preparing a microorganism fermentation feed. The method comprises the main technological processes as follows: respectively culturing Candida utilis, Geotrichum candidum and Streptococcus faecalis with molasses in combination with a liquid microorganism culture medium as the main raw materials; mixing the Candida utilis culture solution, the Geotrichum candidum culture solution and the Streptococcus faecalis culture solution at a certain ratio to obtain a mixed bacteria solution; subjecting to solid fermentation in a semi-solid fermentation culture medium including molasses liquefied liquid, corn coat, vegetable meal, cotton seed meal, wheat bran, soybean meal and apple pomace; baking at a low temperature when the fermentation is finished; and pulverizing to obtain the microorganism fermentation feed. In the microorganism fermentation feed, the viable count of beneficial microorganism is larger than 1*10<9>cfu/g, and the phytase activity is higher than 1,400IU/kg. The feed has the functions of supplementing the number of milk cow (sheep) rumen microorganism, regulating rumen fermentation function, and improving feed conversion and utilization ratio.

Description

technical field [0001] The invention relates to a preparation method of special micro-ecological feed for ruminants, which belongs to a preparation method of rumen-regulated microbial fermentation feed for ruminants. Background technique [0002] With the rapid development of dairy cattle breeding and sheep fattening industry, animal production performance continues to increase. However, the widespread use of antibiotics has led to endogenous infections and drug resistance in animals. Moreover, the beneficial microorganisms in the rumen are violated, die or are excreted along with the digested food, which destroys the micro-ecological balance of the normal flora in the intestinal tract of animals and reduces the production performance of animals, thus affecting the economic and social benefits of the breeding industry . Using the theory and technology of rumen micro-ecological balance in ruminants, the compound microbial agent prepared by cultivating a variety of beneficia...
