Abstract

The invention aims at providing a complex microbial inoculant for livestock breeding. The complex microbial inoculant comprises bacillus subtilis, bacillus natto, bacillus coagulans, lactobacillus rhamnosus, clostridium butyricum, a carrier and a protective agent. According to the complex microbial inoculant, by using a synergistic effect among probiotics, the immunity of bred animals can be effectively improved, the disease resistance of the animals is enhanced, the digestibility of livestock to a feed can be improved, the feed-to-meat ratio is reduced, the interest rate return of feed is increased, the economic benefit is increased for a farmer, and a new environment-friendly breeding mode is realized.

Description

technical field [0001] The invention relates to the field of microorganism application, in particular to a composite bacterial agent for livestock and poultry breeding. Background technique [0002] my country has now become a major country in the production and trade of livestock and poultry in the world. The production scale of poultry eggs ranks first in the world, and the output of poultry products ranks second in the world. The use of antibiotics causes a large amount of drug residues, resulting in the decline of poultry and livestock meat varieties, and the enhancement of bacterial drug resistance, which directly or indirectly affects human health. [0003] In recent years, probiotic products have become a hot spot as a green feed additive. Probiotics form dominant beneficial bacteria through biological competitive exclusion in the digestive tract of animals, and prevent and control the occurrence of diseases by enhancing animal immunity, promoting animal growth, and im...
