Pigs receiving higher protein rations (18%) grew slightly faster than those receiving low protein (15%) rations; however, the differences were not significant. Adding a fermentation product to either ration tested did not significantly improve performance of weaned pigs. Finishing swine were used to compare high-protein (16%) ration and low-protein (13%) rations with and without the fermentation product. Pigs receiving the higher-protein ration grew significantly faster than those receiving the lower-protein ration with or without the additive. Pigs receiving the additive in the 13% ration grew slightly faster than pigs receiving the 13% ration without the additive.SwineGrowing pigsFinishing pigsLactobacillus acidophilusConference paper
