Abstract:
A model for normal growth and accelerated growth resulting from an early-age feed restriction in chickens, has been constructed. The model describes normal growth by a Gompertz equation, whereas compensatory growth is the product of three terms: a time derivative of the Gompertz equation; a compensation factor which is a function of the severity of feed restriction and a time-dependent exponential term. The model was fitted to experimental results obtained in male and female broiler chicks, with the aid of an iterative algorithm, based on numerical integration of the time-function, in two steps. © 1991.
