Embodiment 1

[0035] like figure 1 Shown, the method for cultivating the rapid type yellow-footed hen that is suitable for slaughtering comprises the steps:

[0036] (1) Using the Liyang chicken fast-length line as the breeding material, the average weight of 300-day-old roosters was 4400g, and the weight of hens was 3560g. The egg production rate was 78%, and the number of eggs laid by hens at the age of 66 weeks was 158. After 7 generations of breeding, the Liyang chicken yellow feather slightly hemp feather yellow shank, fast feather, high-yield line was established, that is, the H1 line (H1♂(Z k+ Z k+ )), as the terminal parent.

[0037] (2) Use the self-breeding group of male and female chickens of Liangfeng chicken parent breeders, select male and female chickens with yellow shanks, yellow skin, and jute feathers for self-propagation, and select 300-day-old male chickens for weight according to individual body weight and egg production records 4150g, hen weight 3060g, average age ...

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, ...
