A total of three diets were formulated to contain different levels of soybean meal and synthetic amino acids. Two different soy products were included in the diet based on their analyzed ABC-4 values. The diets were formulated for pigs weighing 7.0 to 12.0 kg of BW.
MEpro, Prairie AquaTech, Brookings, SD.
HP 300, Hamlet Protein, Findlay, OH.
Ronozyme HiPhos 2700 (DSM, Parsippany, NJ) provided an estimated release of 0.13% STTD P with 1,250 FTU/kg.
Individual sample acid-binding capacity-4 (ABC-4) values were used for calculations and not ingredient mean values (Lawlor et al., 2005).
