Abstract

The invention relates to bacillus amyloliquefaciens and application of the bacillus amyloliquefaciens in prevention of diarrhea of weaned piglets. The invention provides a bacillus amyloliquefaciens strain BA40, which can be used for inhibiting common porcine intestinal pathogens, namely escherichia coli K88, salmonella typhimurium and staphylococcus aureus, and has the capabilities of resisting acid, bile salt and pancreatin. After the bacillus amyloliquefaciens is activated, the viable count of the bacillus amyloliquefaciens reaches 108-109 CFU / mL, 6-day-old suckling piglets are subjected to intragastric administration through the mouth, and weaning is performed after 1 mL of the suckling piglets are continuously administrated to the stomach for 24 days. The bacillus amyloliquefaciens provided by the invention can improve weaning weight gain of piglets of pigs and diversity of intestinal flora, reduce diarrhea of the weaned piglets, reduce diarrhea rate, reduce inflammatory factors, promote nutrient absorption and improve oxidation resistance and disease resistance of organisms, and provides a new way for nutrient regulation and control under antibiotic-free breeding.

Description

technical field

[0001] The invention relates to the technical field of microorganisms, in particular to the application of a strain of Bacillus amyloliquefaciens in preventing diarrhea of ​​weaned piglets. Background technique

[0002] Animal husbandry is a pillar industry in my country's agricultural economic industry. For a long time in the past, antibiotics have also played an important role in promoting the development of animal husbandry: promoting growth, increasing feed remuneration, reducing morbidity, and bringing substantial benefits to producers. On the other hand, antibiotics also bring food safety and ecological safety problems, such as causing the imbalance of intestinal flora in animals, inhibiting the function of intestinal barrier, and residual antibiotics reaching the human body through the food chain, which may seriously damage Human health, while causing a series of problems such as the deterioration of the land environment.

[0003] Pig breeding is the la...
