The aim of this study was to evaluate the effects of Enterococcus faecium DSM 7,134 supplementation on the performance of sows and their litters. A total of 15 primiparous sows (Landrace × Yorkshire) were randomly divided into three treatments with five replicates. Dietary treatments were: CON, basal diet; E1, CON + 0.025% E. faecium ; E2, CON + 0.05% E. faecium . No significant differences were observed on body weight and feed intake of lactating sows with E. faecium supplementation, but linearly increased the sow apparent total tract digestibility (ATTD) of dry matter (DM), nitrogen (N) and gross energy (GE; p < .05), and decreased piglets pre‐weaning mortality ( p < .05). Piglets from E. faecium ‐supplemented sows linearly increased weaning weight, average daily gain (ADG) and gain:feed ratio ( p < .05), as well as linearly decreased diarrhoea score ( p < .05) in the first weaning week. Piglets from E. faecium ‐supplemented sows linearly increased faecal Lactobacillus and Enterococci counts ( p < .05), while linearly decreased faecal Escherichia coli counts ( p < .05) after weaning. In conclusion, dietary supplementation of E. faecium improved the ATTD of DM, N and GE in lactating sows, as well as improved body weight, ADG and shifted faecal microbiota in their litters.
