Bacterial strain capable of preventing and treating cattle and sheep diarrheal diseases

Abstract

The invention relates to a bacterial strain capable of preventing and treating cattle and sheep diarrheal diseases. The bacterial strain capable of preventing and treating the cattle and sheep diarrheal diseases is bacillus subtilis and preserved in China General Microbiological Culture Collection Center; and the preservation number is CGMCC NO: 15545. The bacillus subtilis can be applied to plant-eating animal feeding, can also be applied to preparation of plant-eating animal feed additives and can further be applied to preparation of plant-eating animal feed. The bacterial strain provided bythe invention has relatively strong adhesion capacity and antibacterial capacity, has very good acid-resistant capacity, gastrointestinal tract resistant capacity and bile salt tolerance, and can effectively prevent and treat the cattle and sheep diarrheal diseases.

Description

technical field [0001] The invention relates to a bacterial strain capable of preventing and treating diarrheal disease in cattle and sheep. Background technique [0002] Since the 20th century, with the widespread application of antibiotics in feed-grade additives, antibiotics have played an indelible and important role in human medical treatment, livestock and poultry production, disease prevention and control, promotion of animal growth, and increase in the quantity of meat products. In the modern animal husbandry industry, the extensive use of antibiotics in the production of livestock and poultry feed has become the norm. Statistics show that about 50% of the global total antibiotic production is used in the animal husbandry industry. However, due to the long-term use and abuse of antibiotics, their disadvantages are increasingly widely recognized. More and more studies have found that there are many safety problems in the application of antibiotic additives, such as t...

2. When the animals lack probiotics, the micro-ecological balance will be destroyed, and the animals will show various diseases and sub-health states, and the growth and production performance will decline

Compared with developed countries, the research on probiotics in my country started late and has a relatively weak foundation. Although some functional products related to probiotics have appeared in the domestic market, most of the strains used are purchased or introduced from abroad. Known Commercial Probiotic Strains
