Abstract
A breeding method for improving reproductive performance of a chicken specialized dam line includes the steps of forming an F1 generation group, forming a breeding group, screening a breeding group, forming an F2 generation group, and continuously breeding to an Fn generation group. The method includes raising in small-scale groups and natural mating for systematic selection and breeding, which effectively reduces the generation interval and has the features of easy operation and fast genetic progress, not only ensuring animal welfare, but also effectively improving production performance.
