  1. The data are represented as mean ± SD (n = 3) and the values with different superscripts indicate significant differences as determined by Duncan’s test (p < 0.05). (Diet 1: 24.82% inclusion level of PBM, IM, FW, PM, RM and SCP; Diet 2: 28.82% inclusion level of PBM, IM, FW, PM, RM and SCP; Diet 3: 32.82% inclusion level of PBM, IM, FW, PM, RM and SCP; Diet 4: 36.82% inclusion level of PBM, IM, FW, PM, RM and SCP).
