Abstract

Purpose: The aim of the present study was to evaluate the effects of dietary beta-glucans supplementation for gestation and lactation sows of 1st, 2nd or 3rd parity on sows and litters performance, milk composition and Brix value of colostrum, hemogram and serum immunoglobulin G concentration of sows and piglets.

Methods: A total of 78 sows were distributed in a completely randomized design, in a 2x3 factorial scheme, with two supplementation levels (0 and 450 mg/kg of beta-glucans) and three parities (1st, 2nd or 3rd).

Results: No interaction was observed between supplementation and parturition for any of the analyzed variables. The dietary supplementation of purified beta-glucans did not influence the reproductive performance of sows, litter performance and the immune response of 1st, 2nd or 3rd parity sows during gestation and lactation. Third parity sows had heavier litters at farrowing, greater weight gain, higher colostrum Brix value and serum immunoglobulin G than 1st and 2nd parity sows.

Conclusion: It is concluded that dietary supplementation of beta-glucans for gestation and lactation sows of 1st, 2nd or 3rd parity did not affect performance of sows and litters; however, 3rd parity sows had heavier litters, greater weight gain at weaning, higher values of colostrum Brix and serum immunoglobulin G than 1st and 2nd parity sows.
