The experiment was conducted with the goal to evaluate the use of rations with Pediococcus acidilactici and Pediococcus acidilactici plus Bacillus subtilis as probiotics to weaned piglets (21 days) and the effects on the performance until 63 day of age. 210 piglets were submitted to the folowing treatments: T1- ration with Pediococcus acidilactici; T2- ration with Pediococcus acidilactici + Bacillus subtilis; and T3- ration without probiotic. Were evaluated the daily weight gain, daily feed intake and the conversion rate, the dirrohea ocurrence and the mortality rate. The experimental design was a randomized blocks, with 3 treatments and 7 replications, been the means compared by Duncan’s Test. At the end of the experiment the animals that received the ration with Pediococcus acidilactici and the ration with Pediococcus acidilactici plus Bacillus subtilis (T1 and T2) presented a better conversion rate (P < 0.05) than the control group. The use of these bacterias did not result a diarrohea ocurrence. The probiotics used can be indicated with positive results on conversion rate to piglets in the nursery phase.
