Description

technical field

[0001] The invention belongs to the technical field of veterinary microbial additives and is related to the field of antibiotic additives. The invention relates to an Enterococcus faecium (Enterococcus faecium) which has obvious antibacterial effects on common intestinal pathogenic bacteria such as Staphylococcus aureus, Escherichia coli and Salmonella. faecium) strain isolation and identification, safety evaluation, stress resistance performance and probiotic performance identification and use as a feed additive. Background technique

[0002] Since Moore first reported in 1946 that adding antibiotics to feed can significantly increase the daily weight gain of broilers, more than 60 kinds of antibiotics have been used in animal husbandry, playing an important role in the prevention and control of animal diseases and improving the performance of livestock and poultry. However, with the extensive use of antibiotics, especially unscientific abuse, problems such ...
