Problems solved by technology

The invention is a single-type Bacillus subtilis feed additive. Although it can improve the nutritional value of the Bacillus subtilis additive and promote the metabolism of animals, the number of bacteria in the Bacillus subtilis is low in the production process, especially the low spore rate. It greatly affects the quality of the prepared microbial preparation and the amount added in the subsequent feed

Abstract

The invention belongs to the technical field of microbial preparations, and particularly relates to a composite microbial preparation containing bacillus subtilis. The composite microbial preparationcontaining the bacillus subtilis comprises the following components in parts by weight: 40-60 parts of composite microbial powder, 20-30 parts of a composite carrier and 2-10 parts of a protective agent. According to the composite microbial preparation containing the bacillus subtilis, through the mutual coordination effect of bacillus subtilis, bacillus cereus and inulin bacillus, the side effects caused by antibiotic abuse are overcome, and a safe and green composite microbial preparation is provided for human beings; and meanwhile, the number of spores generated in the biological bacteriumfermentation process is effectively increased, and an important guarantee is provided for effectively prolonging the service life of the microbial agent and maintaining the pesticide effect and stability of the microbial agent in the subsequent preparation process of the biological bacterium preparation.

Description

technical field [0001] The invention belongs to the technical field of microbial preparations, in particular to a composite microbial preparation containing Bacillus subtilis. Background technique [0002] Piglet digestive tract diseases seriously restrict the development of healthy pig breeding ("The Epidemic Status and Prevention and Control Measures of Pig Systemic Diseases", Chen Huanchun, Veterinary Guide, Issue 11, 2017, Page 6, Abstract Line 1, Publication Day June 30, 2017). According to statistics, the annual incidence of digestive tract diseases in piglets is as high as 50.47%, the fatality rate of bacterial diseases reaches more than 50%, and the fatality rate of viral diarrhea can reach 100%. In the past 30 years, significant breakthroughs have been made in the detection, prevention and control of piglet digestive tract diseases in my country, but the results are not satisfactory. Livestock and poultry diseases continue to break out and new diseases continue to ...
