Effects of dietary supplementation of Bacillus amyloliquefaciens CECT 5940 and Enterococcus faecium CECT 4515 in adult healthy dogs.

The aim of this study was to evaluate the effect of a probiotic preparation consisting of two probiotic strains, Bacillus amyloliquefaciens CECT 5940 and Enterococcus faecium CECT 4515 (each 5 · 10(8) CFU/g feed), on faecal consistency, faecal microbiology and nutrient digestibility in adult healthy dogs. Sixteen beagles (eight males and eight females) were divided into two groups: the Control group (CON), which was fed the basal diet, and the probiotic group (PRO), which received the basal diet supplemented daily with 1 · 10(8) CFU for 39 consecutive days. Faecal score was assessed before (BS) and throughout the supplementation period (SP).
