Method for breeding low-speed parental breeder black-bone chickens

Abstract

The invention discloses a method for cultivating slow-speed black-bone chicken parent generation breeders. Lingyun black-bone chicken with purified feather color and shank color, low wildness, better egg production performance and reproduction is used as the first male parent of the ancestor; The pure line of Wenchang chicken pearl feather with low egg production performance and reproductive performance is used as the grandparent parent, the rooster of the first father of Lingyun black chicken and the hen of the pure line of Wenchang chicken pearl feather used as the grandparent parent Artificial insemination is carried out, and the female seedlings are selected for the emergence of offspring, which is a kind of slow-speed black-bone chicken parent generation breeder according to the present invention. Compared with the traditional black-bone chicken for breeding, the slow-speed parent generation black-bone chicken of the present invention overcomes the defect of being wild and difficult to raise, and the egg-laying performance of the parent generation is improved by more than 30%, the fertilization rate is increased by more than 5%, and the hatching rate is increased by 3.7%. Above, the rate of healthy chicks has increased by more than 3.2%, which has significantly improved the breeding benefits of black-breed chickens.

Description

technical field [0001] The invention relates to the technical field of poultry genetics and breeding, in particular to the technical field of breeding mating lines of slow-speed high-quality chicken parent generation breeders. Background technique [0002] Because black-bone chicken has the functions of body-building and beautifying, tonifying qi and nourishing blood, it has unique curative effects on insufficient qi and blood, mental fatigue, irregular menstruation, postpartum blood loss, backache, abdominal pain, weak spleen and stomach, and poor diet, etc., so it is popular among consumers. favored by those. However, the traditional black-bone chickens for breeding have defects such as large wildness, low egg production rate, and low reproductive performance of breeders, which makes it difficult to raise black-bone chickens for breeding, and the breeding benefits are low. Therefore, it is difficult to adapt to the scale of black-bone chickens without improving the above-m...

However, the traditional black-bone chickens for breeding have defects such as large wildness, low egg production rate, and low reproductive performance of breeders, which makes it difficult to raise black-bone chickens for breeding, and the breeding benefits are low. Therefore, it is difficult to adapt to the scale of black-bone chickens without improving the above-mentioned disadvantages of traditional black-bone chickens for breeding production requirements
