¹Residual Standard Deviation
²From an analysis of variance with a linear mixed model including the effects of Treatment (T), Breed (B), Period (P), Replicate (R) (and Body weight at Weaning for ADG and BW) and their interactions as fixed effect. Statistical significance: ***P < 0.001, **P < 0.01, *P < 0.05, †P ≤ 0.10
³BW = Body Weight
⁴ADFI = Average Daily Feed Intake
⁵ADG = Average Daily Gain
⁶FE= Feed Efficiency
