F: female, M: male, BW: body weight, FC: feed consumption, FCR: feed conversion ratio, Trt: treatment, β_0–2: model parameters of Gompertz exuqtion, IPT: point of inflection time, IPW: point of inflection weight. The means with different letters in the same column for the subgroups of main effect or interaction are statistically different, * p < 0.05.
