Abstract

The invention provides bacillus coagulans for improving growth performance of white feather broiler. The bacillus coagulans is separated from a digestive tract of healthy poultry; the research shows that the bacillus coagulans is added in daily ratio of the white feather broiler, so that the number of escherichia coli and the ammonia nitrogen concentration in cecum of the white feather broiler, and the microbial diversity index of cecal digesta is improved; besides, the research result shows that by feeding the bacillus coagulans, the mortality and elimination rate and the feed conversion rate of the white feather broiler are improved, and the daily grain of the boilers in experimental group is improved.

Description

technical field [0001] The invention belongs to the technical field of microbial additives and applications, and in particular relates to a bacillus coagulans strain for improving the growth performance of white-feathered broilers. Background technique [0002] Probiotics refer to microbial preparations or other substances that can promote the balance of microbiota (ie, microecological balance) in the intestinal tract of humans and animals, and are widely used in industries such as medicine, health care, food, animal husbandry and aquatic products. It has the functions of regulating intestinal dysfunction, maintaining the balance of intestinal flora and improving the immune level of the body. At present, probiotics widely used at home and abroad include Lactobacillus, Bifidobacterium, Bacillus and yeast, etc., but Lactobacillus and Bifidobacteria have poor resistance to gastric acid, bile salts and high temperature. In recent years, Bacillus coagulans has become a research ...
