Example Embodiment

[0018] The present invention will be further described below in conjunction with specific embodiments.

[0019] The embodiment of the present invention is a breeding method for improving the reproductive performance of a specialized maternal line of chickens. The embodiment includes and preferably executes according to the following steps, breeding chickens in a breeding group to ensure the realization of the above-mentioned technical purpose. The specific steps for:

[0020] Step S1, introduce 8,000 Daheng S05 line chicks as specialized maternal line materials to form F1 generation groups, and the male and female chickens are raised in groups in the brooding cages to the end of 10 weeks of age;

[0021] Step S2, at the end of 10 weeks of age in the F1 generation group, select more than 2000 roosters, the coefficient of variation of body weight and appearance uniformity is not higher than 10%, and carry out small-scale group feeding in rooster cages, with 20 roosters per cage....

Abstract

The invention discloses a breeding method capable of increasing chicken specialized dam line reproductive performance and belongs to chicken breeding methods. The method includes: building a F1 generation colony, building a breeding colony, screening the breeding colony, building a F2 generation colony, continuously breeding to the F(N) generation colony and the like. The method has the advantagesthat systematic breeding is performed by using small-scale colony feeding and natural mating, generation interval is lowered effectively, and the method is convenient and practicable in operation, fast in genetic progress and capable of guaranteeing animal welfare and effectively increasing productivity; the chicken specialized dam line bred by the method is high in reproductive performance, lowin pecking addiction rate and high in survival rate, the colony does not like fight and is quite and high in productivity, and the method has significant scientific and economic values in the increasing of the chicken breeding technology of China and the lowering of chicken breeding cost.

Description

technical field [0001] The invention relates to a breeding method for breeder chickens, more specifically, the invention mainly relates to a breeding method for improving the breeding performance of specialized female lines of chickens. Background technique [0002] The scientific breeding of chickens requires full consideration of the seed production cost and production benefits of commercial generation chickens when formulating breeding programs, which requires that the reproductive performance of specialized female lines must be improved as much as possible. At present, the breeding method for chicken reproductive performance is mainly family selection, but because the family selection method requires single-cage breeding and single-cage measurement, there are troublesome operations, complicated breeding work, animal welfare cannot be guaranteed, and genetic progress is slow and other shortcomings, which makes the family selection method less used in the practice of chicke...
