【 摘 要 】

This work aimed to study the probiotics association in 144 piglets from birth to 62 days old. In lactation, the design was completely randomized with two treatments, CTL, 1 mL of distilled water and ProbA, 5g in 15 ml of distilled water, both orally, and in the nursery in randomized block design, with 2x3 factorial arrangement of treatments, ProbA ProbB: 30g/ton of ProbB in the ration; CTL ProbB: 30g/ton of ProbB in the ration; ProbA ProbA, CTL CTL; ProbA CHA (challenged); CTL CHA. At 35 days of age the animal of the nursery were inoculated with Salmonella typhimurium orally. There was no effect of the parameters evaluated during the maternity. In nursery, the feed conversion was favorable to the ProbA. In the evaluation of fecal score, the challenged group had more diarrhea and increased elimination of S. typhimurium. Results showed the positive action of probiotics when applied at birth by the direct influence on the formation of the intestinal microbiota.
