The objective of this study was to evaluate the effect of a Lactobacillus sp. pool from swine for piglets in the suckling and nursery phases on faecal counts of Lactobacillus, coliforms, Clostridium and Enterococcus. Eighty-one faecal samples were collected at 7, 28 and 49 days of age coming from piglets arranged in a randomized block design under three treatments (A- control diet, B - diet containing a growth promotor, and C, daily probiotic supply from the 1st to 49th day). The tested probiotic did not change efficiently the intestinal microbiota of the animals (P >0.10). However, probiotic treated animals to 49 days had greater Lactobacillus counts and lower coliforms and Clostridium counts than other treatments. The treated animals received greater development benefits from microorganisms, which inhibit patogenic microorganisms.
