Effect of supplementing Saccharomyces cerevisiae fermentation product in sow diets on reproductive performance in a commercial environment

Abstract

Sows (n = 491) were used to determine the effects of dietary yeast culture (Diamond V Original XPC™) on sow and litter performance in three treatments: (1) no added XPC, (2) 5 and 15 g d-1 XPC, and (3) 12 and 15 g d-1 XPC during gestation and lactation, respectively. Litter weight gain of multiparous sows fed XPC tended to be increased (P = 0.051), whereas that of primiparous sows was not affected. Days from wean to successful breeding of multiparous sows was reduced 35% (P < 0.05) by XPC. However, feeding a higher level of XPC during gestation resulted in no additional benefits.Key words: Litter weight gain, parity, sows, Saccharomyces cerevisiae fermentation product
