Breeding method capable of increasing chicken specialized dam line reproductive performance

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...

Problems solved by technology

[0003] One of the purposes of the present invention is to address the above-mentioned deficiencies and provide a breeding method for improving the reproductive performance of the specialized female line of chickens, in order to solve the problem of single-cage breeding and measurement in the family selection method in the prior art, which has troublesome operation and selection problems. The work is complex and technical issues such as animal welfare cannot be guaranteed
