Abstract

The invention aims to provide bacillus subtilis WL-04 and application thereof to livestock breeding. The preservation number of the bacillus subtilis WL-04 is CCTCC NO:M 2013343. The bacillus subtilis WL-04 can be used for remarkably inhibiting the growth of Escherichia coli, salmonella, clostridium pefringens and other conditional pathogenic bacteria of the intestinal canal of livestock, and particularly, the bacteriostasis rate of the bacillus subtilis WL-04 to Escherichia coli and clostridium perfingens is above 75%; the enzyme production is stable; the average activity of alpha-amylase is 22U / mL, and the average activity of neutral protease is 170U / mL; the reproduction of probiotics of intestinal canal can be promoted; high temperature for pelletizing can be endured; the influence of inverse environments with low-pH gastric fluid and high-concentration cholate is endured; the production performance of breeding animals can be effectively improved; immune organ development can be promoted. The bacillus subtilis WL-04 can be widely applied to livestock feeds as a feed additive.

Description

technical field

[0001] The invention belongs to the technical field of microbial screening and application, and in particular relates to a bacillus subtilis WL-04 strain and its application as a feed additive. Background technique

[0002] Nowadays, with the rapid development of large-scale and intensive breeding, there have been problems such as excessive stocking density and poor ventilation in the breeding house, and the quality of the breeding environment has declined. Various digestive tract diseases of livestock and poultry caused by conditional pathogenic bacteria have a great impact on the environment. Breeding problems are also becoming more and more prominent, such as colibacillosis, salmonellosis, and necrotic enteritis caused by Clostridium perfringens. In order to achieve the purpose of preventing diseases or promoting animal growth, a large number of antibiotics are used in multiple links of livestock and poultry production. The long-term use and abuse of anti...
