Abstract

The objective of this study was to determine the effect of replacing corn and Soybean Meal (SBM) with Brewers Rice (BR) and Dried Distillers Brewers Yeast (DDBY), respectively, on ADG, G:F, Apparent Total Tract Digestibility (ATTD), fecal DM output and fecal loss of N and P of growing-finishing pigs. Sixty four Yorkshire x Duroc x Hampshire crosses (BW = 73±5.7 kg) were randomly assigned to corn/SBM (CSM), BR/SBM (RSM), corn/DDBY (CBY) or BR/DDBY (RBY) diets. Compared with pigs finished on corn based diets, pigs fed BR based diets gained faster (0.868 vs. 0.730 kg.pig-1; p<0.01) and had better gain to feed ratio (0.30 vs. 0.25; p<0.01). Pigs finished on RBY diet had the least fecal DM output (0.245, 0.352, 0.575, 0.639 kg.pig-1; p<0.001) and greatest ATTD (91.5, 87.8, 80.0, 77.9%; p<0.001) followed by RSM, CBY and CSM pigs, respectively. Pigs finished on RBY diet lost the least (p<0.001) amount of N (0.010, 0.013, 0.019, 0.021 kg.pig-1) and P (0.010, 0.014, 0.016, 0.019 kg.pig-1) in the feces followed by pigs finished on RSM, CBY and CSM, respectively. In conclusion, BR and DDBY can replace all corn and SBM in swine diets with no negative effects on performance of growing-finishing pigs.
