Abstract: Bacillus subtilis is an ideal probiotic species that can form spores with a variety of physiological functions and is non-toxic and has no side effects on animal organisms.Adding Bacillus subtilis to feed can regulate intestinal function,balance microbial flora,enhance immunity,and promote growth.Bacillus subtilis can also be used as a feed fermentation strain.The fermented feed will reduce the content of anti-nutritional factors and increase the content of nutrients,thereby promoting the digestion and absorption of feed nutrients by livestock and poultry.The characteristics of Bacillus subtilis endophytic spores can ensure its functional stability in feed production and livestock and poultry internal environment and its unique advantages as a vaccine expression vector.Therefore,Bacillus subtilis has a very broad application prospect in livestock and poultry production.The authors reviews the biological characteristics,physiological functions,and application of Bacillus subtilis in livestock and poultry production,in order to provide some reference for the application of Bacillus subtilis in livestock and poultry production.

Key words: Bacillus subtilis; intestinal microbiota; fermentation strain; vaccine expression vector
