Primer group for breeding slow-feathering homozygous yellow-foot partridge chickens and breeding method of quick yellow-foot partridge chickens suitable for slaughtering

Abstract

The invention discloses a primer group for breeding slow-feathering homozygous yellow-foot partridge chickens and a breeding method of rapid yellow-foot partridge chickens suitable for slaughtering. The primer group comprises a fast-feathering primer pair and a slow-feathering primer pair, the nucleotide sequence of a forward primer of the fast-feathering primer pair is shown as SEQ ID No.1, and the nucleotide sequence of a reverse primer of the fast-feathering primer pair is shown as SEQ ID No.2; the nucleotide sequence of a forward primer of the slow feathering primer pair is shown as SEQ ID No.3, and the nucleotide sequence of a reverse primer of the slow feathering primer pair is shown as SEQ ID No.4. According to the fast and slow feathering auto-sexing genetic principle and the designed fast and slow feathering genetic typing specific primers, fast feathering, slow feathering and slow feathering heterozygotes and homozygotes can be rapidly distinguished, a homozygous slow feathering strain is cultivated, and fast and slow feathering auto-sexing of commercial generations is achieved.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a primer set for breeding slow-feather homozygous yellow-footed pheasants and a method for cultivating fast-type yellow-footed pheasants suitable for slaughter. Background technique [0002] With the accelerated pace of life of the younger generation, the proportion of fast-food chicken consumption that is simple and easy to cook is increasing. The demand for high-quality yellow-feathered broilers with beautiful carcass and well-developed breast and leg muscles will continue to grow. Yet, also lack the rapid type yellow-leg hemp broiler breed that is suitable for slaughtering on the markets such as East China, Guangdong, Guangxi, and Southwest at present. Cultivate a new breed of high-speed, high-quality yellow-feathered broiler chickens (supporting line) suitable for slaughtering and marketing, which meets the extensive needs of the slaughtering markets in East China, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problem of low efficiency of male and female identification of commercial chickens mentioned above, the present invention provides a primer set for the cultivation of slow-feather homozygous yellow-footed hen and a method for cultivating a fast type of yellow-footed hen suitable for slaughter. A new breed of high-quality chilled fresh chicken that is genetically stable and can be directly used for slaughtering production is bred through a three-line matching model with carcass packaging traits that clearly identify high-quality chickens.
