SBM = commercial soybean meal. Basal diets were prepared when the SBM was replaced by RFFS at 0, 15 and 25%, equivalent to 0, 45 and 75 g/kg of diet, respectively)
Microbial protease was then supplemented to the basal diets (0 or 15,000 PROT/kg of diet). A 15000 PROT/kg = 15,000 units of protease/kg of diet, equivalent to 200 mg of protease/kg of diet. The 3 experimental periods of this study were starter (day 0 to 10), grower (day 10 to 24) and finisher (day 24 to 32). FYT = FTU as a unit that measuring the releasing capacity of nutrient by microbial phytase. NFD = nitrogen free diet
