Effects of dietary supplementation of probiotic Enterococcus faecium on growth performance and gut microbiota in weaned piglets.

ABSTRACT: The adverse effects of antibiotics have attracted widespread attention, thus reducing the use of antibiotics in animal feed has become a very important issue in improving of the health of livestock. The effects of Enterococcus faecium (E. faecium) on growth performance and gut microbiota in weaned piglets were investigated in the present study. Piglets were randomly assigned to four treatments: a control group fed with a diet containing 75 mg/kg aureomycin (Diet 1 group) and three experimental groups fed with diets of 50 mg/kg aureomycin (Diet 2 group), 50 mg/kg aureomycin + 9 × 10⁵ CFU/g E. faecium (Diet 3 group), or 50 mg/kg aureomycin + 1.2 × 10⁶ CFU/g E. faecium (Diet 4 group). Their gut microbial communities were analyzed by sequencing the V3-V4 region of the 16S
