Abstract

The invention relates to a cockscomb-droop-free high-quality chicken breeding method comprises the following steps: taking local chicken varieties as breeding materials; carrying out four times of breeding according to the breeder selection parameter indexes of male and female chickens to establish a family, wherein the cockscomb base thickness is a key breeder selection parameter; after the family is established, breeding the non-inbred male and female chickens in the family to breed the next generation of chickens; and repeating the previous process of breeding the next generation of chickens for at least three generations to obtain the cockscomb-droop-free high-quality chickens. The method is simple in operation, excellent in breeding effect and easy to popularize, makes results accurate, and the cockscomb-droop proportion of chickens is zero after breeding for more than three generations. In addition, when the chickens undergo cockscomb-droop improvement, and the breeding of othercharacters is not neglected, so that the comprehensive performance of the products is improved, and the market competitiveness is better.

Description

technical field [0001] The invention relates to a poultry breeding technology, in particular to a method for breeding high-quality chickens without inverted crowns. Background technique [0002] Broiler chicken consumption in foreign countries is dominated by the slaughter of large white chickens. On the one hand, the fast big white chicken has a small comb, so it doesn’t matter whether it has an inverted comb or not. On the other hand, consumers don’t pay attention to whether it has an inverted comb. Therefore, there are almost no research reports on the trait of inverted comb of chickens in foreign countries. However, due to the inherent domestic sales methods and consumption habits, the inverted crown trait is still one of the traits that must be paid attention to in the breeding process of yellow-feathered broilers, especially medium-speed and slow-speed broilers. Domestic yellow-feather broiler chicken breeding companies will select for the inverted crown trait during ...
