1 SGR, Specific growth rate = 100 × ln (final weight/initial weight)/days. 2 FI, feed intake = 100 × feed consumption (g)/average biomass (g) × days. 3 FCR, feed conversion ratio = feed consumption (g)/biomass gain (g). 4 PER, protein efficiency ratio = biomass gain (g)/protein intake (g). Means of triplicate groups. Values are presented as mean ± SEM (n = 3). Values in the same row with different superscript letters are significantly different (p < 0.05). Initial weight was considered as covariable for final weight and SGR.
