We select 200 chickens of North China chai chicken to do the experiments. The raising term is 16weeks. The weight is measured at birth and at the end of every week to calculate the absolute weight gain, the relative weight gain. From the experimenting results we can see the absolute weight gain peaks of the North China chai chicken at the 16th week. Male chicks and female chicks weight gain values are slightly different, but the time of growth peak is basically the same.
