LW = live weight; BMW = breast muscle weight; TMW = thigh muscle weight.

W_m = the parameter of mature body weight or body component weight; B = the parameter of the growth rate for the body weight or body component weight before maturity; t^∗ = the age parameter of body weight or body component weight reaching the maximal growth rate; R² = fitting degree of model.
