Breeding method of premature slaughter processing type high-quality chicken commercial line

Abstract

The invention discloses a breeding method of a premature slaughter processing type high-quality chicken commercial line, and belongs to the technical field of poultry genetic breeding and propagation. The breeding method comprises the following steps: (1) taking a fast big blackpock chicken as a material, and carrying out generation breeding to obtain a slow-feathering fast big blackpock chicken as a terminal male parent; (2) taking a short blackpock chicken as a material, carrying out generation breeding to obtain a fast-feathering short blackpock cock as a first male parent; taking a fast big yellow feather chicken as a material, carrying out generation breeding to obtain a slow-feathering fast big yellow feather hen as a first female parent; hybridizing the first male parent and the first female parent, and breeding a fast-feathering hen which is grain-saving, fast in growth and high in laying rate to serve as a terminal female parent; and (3) hybridizing the terminal male parent and the terminal female parent to produce the slaughter processing type high-quality chicken commercial line. The commercial line cultivated with the method is good in prematurity and excellent in slaughter trait.

Description

technical field [0001] The invention relates to the technical field of poultry genetics, breeding and reproduction, and more specifically relates to a method for cultivating a precocious slaughtering and processing type high-quality chicken mating line. Background technique [0002] In recent years, with the increasing complexity of the prevalence of zoonotic diseases, safety risks have intensified, highlighting the safety issues of live poultry trade. Because the food safety monitoring of live poultry trading is difficult, and it is easy to cause certain environmental pollution, and even provide corresponding transmission channels for diseases, there is a large public safety risk. Therefore, the high-quality broiler industry urgently needs to be transformed into large-scale breeding and centralized slaughtering. , cold chain distribution, and chilled products. However, looking at the development of the high-quality chicken industry, the breeding focuses on appearance trait...

Problems solved by technology

Because the food safety monitoring of live poultry trading is difficult, and it is easy to cause certain environmental pollution, and even provide corresponding transmission channels for diseases, there is a large public safety risk. Therefore, the high-quality broiler industry urgently needs to be transformed into large-scale breeding and centralized slaughtering. , cold chain distribution, chilled listing

However, looking at the development of the high-quality chicken industry, the breeding focuses on appearance traits such as feather color, skin color, shank color, crown height, reproductive performance, and meat quality improvement, while ignoring carcass traits. The original high-quality chicken products, especially slow-growing high-quality chickens Not suitable for slaughtering

Representative enterprises try to cultivate slaughtering and processing high-quality chicken matching lines, but there are still problems such as low slaughter rate, high defective rate, and unsightly carcass
