New research presented at the 51st Swine Research Days (Journées de la Recherche Porcine) in Paris, showed how a supplement containing vegetal superoxide dismutase (SOD) and selenium yeast as primary cellular antioxidants, benefits sows reproductive performance1.

In the trial presented, the sows supplemented during the weaning-to-estrus interval showed improved return to estrus and farrowing rates in the subsequent cycle. In addition, they gave birth to more piglets, with significantly more born alive piglets and less stillborn piglets (Figure 1).

CONTROL ANTIOX P value
Return to estrus (%) 5.33 1.46 0.002
Farrowing rate (%) 87.24 93.69 0.004
Born alive piglets/litter 14.24 14.98 0.036

Fernando BRAVO DE LAGUNA, R&D Swine Project Leader, who presented the study, explains: “Hyperprolific sows are subject to important oxidative stress and previous study2 had already shown that sow supplementation with cellular antioxidants during the weaning-to-estrus interval could improve piglets’ maturity and litter homogeneity at birth. This complementary study also proves that piglets’ quality at birth is improved and that sow’s reproductive performance is enhanced. Supplementation with cellular antioxidants during the weaning-to-estrus interval clearly appears as a good practice in high productive sows.”
