growing/finishing pigs were fed up to 23% brewers dried grains without a significant reduction in gain or a decline in carcass quality. As the level of dried brewers grains in the diet increased, so did the fiber level. The reduction in performance (ADG) occurred when the fiber level in the diet dry matter increased to more than
6%. The rate of feed conversion was less efficient in pigs receiving the brewers dried grains. These authors also concluded that dried brewers grains could supply up to 50% of supplemental protein needs without a decrease in performance. Walhstrom and Libal [16] successfully used up to 40% brewers dried grains in the diet of gestating sows. Gestation weight gains of 39.5,47.6, and 32.7 kg were significantly different for sows fed 0%, 20%, and
40% brewers dried grains, respectively. There were no treatment differences
in reproductive performance. Litter size and weight of individual piglets,
litter weight at birth, and weaning were not affected by treatment.
