SANCHES, Ana Lígia et al. Probiotic, prebiotic and symbiotic in weanning piglets rations. Ciênc. agrotec. [online]. 2006, vol.30, n.4, pp.774-777. ISSN 1981-1829.

The objective of this study was to evaluate the effect of probiotic, prebiotic and symbiotic on the growth performance in the weanning piglets with 23 days old. A total of 96 weaned at 23 days old piglets, with the initial weight of 7.40 kg were distributed in a randomized block design with four treatments with six replicates and four pigs for experimental unit, to evaluate the performance during the period of 35 days. The diets were formulated based on corn and soybean meal, modified dried milk, isoproteic and isocaloric to meet the nutritional needs of the piglets accord to NRC (1998). The 4 treatments were based on: addition of antibiotic; probiotic, prebiotic and synbiotic as additive in the rations. It was observed that the tested additives had no influence (P > 0.05) on the weight gain, feed intake and feed conversion over all experimental period. In conclusion the addition of probiotic, prebiotic or symbiotic in the piglets rations weanning at 23 days old shown similar action to those obtained with antibiotic.
