Hybrid seed production method of high uniformity yellow chicken complete set line suitable for chilled marketing

Abstract

The invention belongs to the technical field of poultry genetic breeding, and particularly relates to a hybrid seed production method of high uniformity yellow chicken three-line combination suitablefor chilled marketing. According to the method, a slow-feathering, yellow-feathering and green-shank chicken line is adopted as a first male parent, a fast-feathering, yellow-feathering, yellow-shank,high-yield and high-quality chicken line is adopted as a first female parent, and hybridization is conducted to obtain an F1 female parent; a local chicken line which is fast-feathering, and yellow-feathering, jute-feathering, sexual precocity and big cockscomb in appearance with the weight within + / -10% of the average weight is selected as a terminal sire, and hybridization is conducted betweenthe terminal sire and the F1 female parent to obtain commercial generation with high uniformity. According to the method, by means of regular and molecular breeding, selections of physical conformation, sexual precocity, weight uniformity and slaughter traits and comprehensive selection of meat quality traits are focused on and carried out, the bred yellow chicken commercial generation is high inuniformity and survival rate, and significant in heterosis; and the chicken has big cockscomb, green shank, fine pores and firm skin.

Description

technical field [0001] The invention belongs to the technical field of poultry genetics and breeding, and more specifically relates to a seed production method with high uniformity suitable for matching three lines of cold-fresh marketed yellow chickens. Background technique [0002] Broiler breeding in foreign countries is dominated by fast and large white feather broiler chickens, and there is basically no high-quality chicken breeding. At present, the European Union, the United States, Japan, etc. are paying more and more attention to the breeding and production of high-quality broiler chickens, but the small-scale high-quality broiler breeding carried out abroad is mainly used for farmers. Stocking is completely different from the direction of high-quality chicken breeding in China. The high-quality chicken industry is a traditional industry with Chinese characteristics. It is mainly marketed with live poultry. With the expansion of the concept of high-quality chicken, t...

[0003] Broiler chicken consumption in foreign countries is only marketed in a cold or frozen way, while the traditional consumption of high-quality chicken in my country has always been dominated by live chickens. Since the H7N9 influenza infection occurred at the end of March 2013, 85% of the yellow-feathered broiler chicken industry traded in the form of live chickens hit hard
