PSXIII-B-7 Effect of Replacing soy Protein Concentrate with Corn Fermented Protein on Growth Performance and gut Integrity of Weaned Pigs

Abstract NexPRO™, a corn fermented protein (CFP) derived from the dry-mill bioethanol production process, has demonstrated potential as high-quality ingredient in weaned pig diets. Therefore, objective of this study was to determine effects increasing dietary inclusion CFP replace soy concentrate (SPC) diet on weight gain, feed intake, efficiency and gut integrity pigs large-scale system. A total 1144 were distributed evenly into 44 pens (13 barrows 13 gilts/pen; initial BW 6.0±0.1 kg) with 286 assigned per treatment 11 replications. The four treatments designed titration at 0%, 4%, 8% 12% Phase 1 (3.6 kg/hd budget) 2%, 4% 6% 2 (5.5 replacing SPC. Pigs fed common through 3.
