Feeding a Fermented Soy Protein-Swine

Korean researchers reported results of a nursery pig study where soybean meal in the basal corn-soybean meal diet was replaced with a fermented soy product. Average daily gain, feed intake, dry matter and nitrogen digestibilities were not affected (P>0.05) by the dietary treatments during the 28-day study. Feeding 10 or 15% fermented soy product to pigs initially weighing 8kg improved feed efficiency, amino acids digestibility and blood urea nitrogen and total protein concentrations in the blood. This study supports the conclusion that fermenting the soy protein may improve its utilization.
