Problems solved by technology

This method is referred to as "sibling selection method". The sibling selection method is time-consuming and laborious, and requires too much hardware and software for breeding enterprises. It is difficult to fully promote and apply it in China's high-quality chicken breeding industry, where the current breeding level is still relatively backward.

Abstract

The invention relates to a method for breeding high-quality chickens low in abdominal fat percentage. The method comprises the steps that a local chicken variety serves as a breeding material; breeding chickens are selected according to breeding chicken reserving parameters and indexes of chickens different in day age, and a family is built, wherein the right shin length of cocks and hens is an important breeding chicken reserving parameter; non-consanguineous cocks and hens are mated and breed a next generation of breeding chickens; the above processes are repeated on the next generation of breeding chickens, and at least after breeding of two generations, the high-quality chickens low in abdominal fat percentage are obtained. The method is easy to operate, accurate in result, excellent in breeding and easy to popularize, and the abdominal fat percentage of the chickens bred after two generations or more is reduced. In addition, breeding of other characters of the chickens are not reduced while the abdominal fat percentage of the chickens is improved, so that the comprehensive performance of products is improved, and the market competitiveness is better.

Description

technical field [0001] The invention relates to a poultry breeding technology, in particular to a method for breeding high-quality chickens with low abdominal fat rate. Background technique [0002] Compared with Kuai Da Bai chicken, Chinese local high-quality chicken generally has the problem of excessive abdominal fat. Excessive abdominal fat, on the one hand, reduces feed utilization efficiency and increases feeding costs; on the other hand, it also affects selling price and sales difficulty. Therefore, domestic high-quality chicken breeding enterprises are selecting high-quality chicken belly fat by some means. At present, there are mainly two methods to select abdominal fat. One is live phenotype selection, that is, breeders touch the abdomen of high-quality chickens one by one, and eliminate the individuals who are considered to have more abdominal fat, and keep the seeds for the next generation. This method is referred to as "living hand-touching method" for short. ...
