Embodiment 1

[0048] A kind of high-quality chicken male line breeding method, it comprises the following steps:

[0049] A. Pengxian Yellow Chicken was used as the male parent and Huainan Sanhuang Chicken was used as the female parent for crossbreeding. Among the offspring, the selected individuals were selected for the selected traits of green legs, good precociousness, long tail and long distance, and then crossed and fixed, closed selection Cultivate a generation of core group and foundation group;

[0050] B. The chickens in the core flock of the first generation are artificially bred and screened to keep individuals with excellent traits. There are 1,500 hens and 70 roosters, and the hens and roosters are paired for breeding. Eggs are collected and incubated once every 14 days, and a total of 20 batches are bred , 200,000 seedlings emerged;

[0051] C. Each batch of chickens is artificially bred and screened, and 100 hens and 5 roosters are selected for each batch of chickens. The...

Abstract

The invention discloses a high-quality paternal chicken breeding method. A paternal circulation breeding method is adopted. A certain quantity of hens and cocks are adopted for breeding. Time of breeding high-quality paternal chicken is reduced. Only 2-3 years are required for breeding the high-quality paternal chicken while 10 years are usually required for standardized breeding. In the breeding process, in combination with artificial breeding and screening, characters of individuals can be highlighted, the individuals with excellent characters can be conveniently selected for breeding, the paternal performance can be obviously improved, the breeding progress is accelerated and the appearance characters are obviously improved. By adopting a method of selecting individuals and increasing selection pressure for characters with high heritability, new lines can be formed within short time.

Description

technical field [0001] The invention relates to a poultry breeding method, in particular to a high-quality chicken male breeding method. Background technique [0002] Pengxian yellow chicken is one of the excellent chicken breeds in Sichuan Province.
