¹⁾

Cont, standard broiler ration; PBM, control diet with 25% of the soybean meal replaced by poultry by-product meal (PBM) on an equivalent protein basis; PBMP, PBM diet supplemented with 0.5 g/kg of protease; PBMO, PBM diet supplemented with 1 g/kg organic acid; PBMPO, PBM diet supplemented with 0.5 g/kg protease and 1 g/kg organic acid.
