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

Abstract

The invention discloses a method for breeding low-speed parental breeder black-bone chickens. The method comprises the steps: adopting Lingyun black-bone chickens, which are purified in feather color and shank color, relatively low in wild nature and relatively good in egg-laying performance and reproduction, as progenitor first male parents; and adopting a pearl-feather pure line of Wenchang chickens, which are low in wild nature and excellent in egg-laying performance and reproductive performance, as progenitor female parents, subjecting cocks of the Lingyun black-bone chickens as the progenitor first male parents and hens of the pearl-feather pure line of the Wenchang chickens as the progenitor female parents to artificial fertilization, carrying out offspring breeding, and selecting female offspring, i.e., the low-speed parental breeder black-bone chickens. According to the method, compared with the traditional breeder black-bone chickens, the low-speed parental breeder black-bone chickens have the advantages that the defects of high wild nature and difficulty in feeding are overcome, the parental egg-laying performance is improved by 30% or more, the fertilization rate is increased by 5% or more, the hatching rate is increased by 3.7% or more, the healthy chick rate is increased by 3.2% or more, and the culture benefit of the breeder black-bone chickens is remarkably improved.

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
