Evaluation of How Nursery Pig Performance is Affected by Fermented Corn Protein as a Replacement to Enzymatically Treated Soybean Meal Along With High or Low Branch Chain Amino Acid to Leucine Ratios

Two experiments were conducted to determine if fermented corn protein can serve as a replacement enzymatically treated soybean meal and what the effects may be with high or low branch chain amino acids (BCAA):Leu ratios on nursery pig performance. In Exp. 1, total of 350 barrows (200 × 400, DNA; initially 13.2 lb) randomly allotted 1 5 treatments pigs per pen 14 replications treatment. Dietary arranged in 2 + factorial control diet diets 10% meal. Pigs fed phase for 10 d followed by 21 d. There no interactions observed throughout experiment. Overall (d 0 31), increasing levels had decreased (linear, P ≤ 0.026) BW, ADG, ADFI differences F/G, whereas effect growth improved (P 0.034) F/G compared diets, ADFI.
