摘要：
The purpose of this study was to screen Probiotic can improve feed utilization rate,improve broiler gut environment, reduce emissions of ammonia in the purpose of broiler manure. Through the simulation of the digestive tract of broiler environment,high yield cellulase, amylase, protease, screening of microbial inhibition of gutharmful bacteria, and conduct the feeding experiment. The results show that the concentration of ammonia in the chicken house when feeding Bacillus subtilis for 58 hours was 13.814 mg / m(3), which was lower than that of the People 's Republic of China Agricultural Industry Standard NY / T 1167-2006 Environmental Quality Standard for Livestock and Poultry Farms, Experiments show feeding broilers with Bacillus subtilis can reduce the production of harmful gas ammonia and effectively improve the environment of livestock and poultry houses.
