Brewers dried grains as a nutrient source in diets for pregnant sows.

Twenty-eight primiparous and 62 multiparous sows were bred and assigned to gestation treatments in which they were fed diets conraining O, 20 or 40% brewers d r i ed grains (BDG). Diets were formulated to be equal in lysine content and were hand fed to supply equal levels of metabolizable energy per sow daily. All sows received a 15% protein corn-soybean meal diet during a 21-day lactation period. Gestation weight gains of 39.5, 47.6 and 32.7 kg were significantly different for sows fed 0, 20 and 40% BDG, respectively. Litter size of live pigs and litter and individual pig weight at birth and weaning were not affected by gestation dietary treatment. Muhiparous sows gained less during gestation and farrowed more live pigs and heavier litters than primiparous sows. Individual pig weights at birth decreased as litter size increased. This study indicated that BDG could be used in diets for pregnant sows. (
