Abstract
The invention discloses microbiological feed which comprises the following components in parts by volume: 10-20 parts of bacillus cereous fermenting liquor, 20-40 parts of lactobacillus casei, 20-40 parts of enterococcus faecium liquor and 20-40 parts of saccharomyces cerevisiae liquor. The four bacteria are fixedly planted at the upper, the middle and the lower parts of the intestinal tract respectively and can inhibit the breeding and invasion of harmful bacteria in the whole intestinal tract, remove harmful substances at all parts of the intestinal tract, resist infection and maintain the flora balance of the digestive tract. All bacteria form joint flora which can grow under different conditions and have rapid and durable effect at different parts of the intestinal tract; a biological barrier is formed on the mucosa surface of the whole intestinal tract, prevents the growth and breeding of conditional pathogens of pathogens and removes endotoxin; and the multi-strain synergy can ensure that the microbiological feed is exerted to the optimal degree and is suitable for various host animals at maximum.
Description
