A high-quality chicken culturing method

Abstract

The invention provides a method for breeding qualitative chicken with low cost, comprising following steps: (1) employing China strain with fast growth rate, yellow feather, short shank, regular shape and uniform weight as the second male parent for mating system; (2) employing strain of yellow feather, precocity, high productivity and high regularity as the first female parent for mating system; (3) using short genotypic strain with yellow feather, regular shape, even weight, high property for breeding and strong vitality as the first male parent for mating system; (4) crossing with cock of said short genotypic strain with hen of high productivity and getting the second female parent for mating system; (5) crossing with the second male parent cock and the second female parent hen and breeding qualitative chicken with low cost.

Description

technical field [0001] The invention relates to a chicken breeding method, in particular to a high-grade, low-cost and high-quality chicken breeding method. Background technique [0002] There are few studies on the breeding and utilization of high-quality chickens abroad, and the research in this area in my country is mainly concentrated in Guangdong, Beijing, Shanghai and Jiangsu. During the "Sixth Five-Year Plan", "Seventh Five-Year Plan", "Eighth Five-Year Plan" and "Ninth Five-Year Plan", many domestic units have carried out research on the selection and utilization of high-quality chickens, and have made certain progress. Since the late 1980s, many domestic units have introduced fast and large broilers from abroad to carry out crossbreeding with local chicken breeds in my country to produce improved commercial broilers, thus greatly improving the growth rate and feed utilization rate of commercial broilers. Chicken production has played a big role in promoting. Howeve...

Problems solved by technology

However, we are also soberly aware that there are still some serious problems in my country's high-quality chickens, the most important of which is: the high-quality yellow chicken breeds or matching lines that currently dominate the market do not have high technological content, and most of the breeds have not been systematically selected. Local chicken breeds or simple hybrids of local chicken breeds and improved breeds, the cost of seed production remains high, especially in the low egg production of parental breeders, the annual egg production of cultivated breeds is about 150, and the local breeds are low. less than 80 chickens; the utilization rate of commercial substitute feed is low, and the production efficiency is low, which cannot effectively meet the breeders' needs for high-end and high-quality chickens
