RESUMO

The experiment was carried in the gestation and farrowing environment of the Faculty of Veterinary Medicine and Zootechny at University of Sao Paulo, in Pirassununga, to evaluate the effect of lactic acid probiotic bacteria administration on weight gain of a specific group of piglets just after the birth and before first colostrum suckling. For a better comparison, we designed another group of piglets, placebo, which received distilled water in the same volume and manner as probiotic group. All the animals were weighed weekly since birth until weaning, occurred with 21 days old. The average daily weight gain ranges also were considered. The tested probiotic did not change efficiently the weight gain of the animals (P>0,05), however, probiotic treated animals had greater average daily weight gain counts, mainly obvious at 7 and 14 days old, being able to justify the hypothesis of the nutrients economy existence, used by the host, owner of a stable and healthy microbiota.
