Abstract

In this paper, the laying rate of 72-week-old Jinyun ducks was fitted using Lorentz model, Polynomial model, Boltzmann model and Wood model, which gave R2 values as 0.63386, 0.96883, 0.91554 and 0.7240, respectively. This result revealed that Polynomial model is found to be the best to fit egg production curve in Jinyun ducks amongst these four mathematical models.

Keywords and phrases: Jinyun ducks, mathematical model, fitting effect.
