Embodiment 1

[0006] A method suitable for sex identification of three-line black-feathered and black-skinned black-bone chickens. When producing parent seedlings, the purified first male parent rooster and reed flower genes and The female parent hens were mated after the main chicken feather deletion type slow feather gene was purified, and the eggs were collected for incubation. After emergence, 6000 chicks were randomly selected, and distributed to 6 people on average for gender identification, and each person identified 1000 chicks. Among them, 3 are specialized technicians who have been trained and are proficient in the essentials of anus turning technology, and use the traditional anus turning method to identify the sex of chicken chicks; the other 3 are personnel who have no experience in identifying the sex of chicken chicks. Chicks with and without white spots are grouped. Using the traditional anus turning method to identify black-feathered and black-skinned chickens took an aver...

Embodiment 2

[0008] Applicable to the method for gender identification of three-line matching black-feathered and black-skinned black-bone chickens, when producing commercial seedlings, obtain the purified second male parent with the fast feather gene and feather color gene and the parental generation hen described in paragraph [0007] Mating, collecting eggs for incubation. After emergence, 6000 chicks were randomly selected, and distributed to 6 people on average for gender identification, and each person identified 1000 chicks. Among them, 3 are specialized technicians who have been trained and are proficient in the essentials of anus turning technology, and use the traditional anus turning method to identify the sex of chicken chicks; the other 3 are personnel who have no experience in identifying the sex of chicken chicks, and carry out identification and grouping by observing the fast and slow plumage of chicken chicks. Using the traditional anus turning method to identify black-feath...

Abstract

The invention discloses a sex determination method suitable for three-line matching black feather black skin type silkie. The method includes the steps that black feather black skin type silkie with a fast-feathering gene and a feather color gene purified is used as a second male parent; black feather black skin type silkie with a feather color gene and a main wing feather deletion type slow-feathering gene purified is used as a first male parent; luhua chicken with a luhua gene and a main wing feather deletion type slow-feathering gene purified is used as a female parent. When parent generation breed chicks and commercial generation chicks are produced in a three-line matching mode, male chicks of the parent generation chicks are characterized in that obvious white spots exist on the head tops, and female chicks of the parent generation chicks are characterized in that no white spot exists on the head tops. Male chicks of the commercial generation are characterized by being of slow-feathering type, and female chicks of the commercial generation are characterized by being of fast-feathering type. The defect that when a traditional anal turnover sex determination method is used for distinguishing the black feather black skin type silkie, errors are large, much time is consumed, the chicks are prone to damage are overcome, and the method is high in sex determination speed of the black feather black skin type silkie, high in efficiency and small in error and causes little damage to the chicks.

Description

technical field [0001] The invention relates to the technical field of genetic breeding of poultry, in particular to the technical field of breeding of matching lines of black-bone chicken. Background technique [0002] Most of the skin colors of chickens can be divided into three types: black skin, yellow skin and white skin. At the time of emergence of black-skinned chickens, due to their black-skinned characteristics, the genital protrusions of the cloaca are not as obvious as those of yellow-skinned chickens and white-skinned chickens. The traditional anus-turning method for gender identification has large errors, and if the reproductive protrusions are observed too carefully, it is easy to cause harm to the chicks. The disadvantages of injury. Contents of the invention [0003] The present invention provides a method suitable for gender identification of black-feathered and black-skinned black-bone chickens with three lines of mating. The first male parent must be ...
