Equations for modeling the growth of Korean native chicken

Model Equation
Gompertz W(t) = αeβeγt
von Bertalanffy W(t) = α(1 − βeγt)3
Logistic W(t) = α/(1 + βeγt)

W(t) is the corresponding weight at time t; α, asymptotic live body weight (gram); β, the log-function for the proportion of the asymptotic mature weight to be gain after birth (wk); γ, a constant scale that is proportional to the overall growth rate (wk).
