Method for breeding high-quality colored-feathering meat and egg-type chicken by using Babcock B380

Abstract

The invention discloses a method for breeding high-quality colored-feathering meat and egg-type chicken by using Babcock B380. The method comprises the steps of 1, hybridizing black-tail fast-feathering Babcock B380 of which a recessive white locus is a heterozygote as a female parent and a recessive white fast-feathering individual of a colored-feathering local variety as a male parent to breed into a white fast-feathering line; 2, hybridizing slow-feathering Babcock B380 of which the recessive white locus is a wild heterozygote as the female parent and a colored slow-feathering local varietyof which the recessive white locus is the wild heterozygote as the male parent to breed into a colored slow-feathering line; and 3, hybridizing the bred white fast-feathering line as the male parentand the colored slow-feathering line as the female parent to produce commercial seedlings of high-quality colored-feathering meat and egg-type chicken. Compared with an existing method for breeding high-yield laying chicken, the method disclosed by the invention has the advantages that the process is accelerated, and the bred female commercial seedlings can be independently distinguished from themale commercial seedlings; compared with the local varieties, the high-quality colored-feathering meat and egg-type chicken has the advantages that the egg yield is increased, the quality is good andcombination of meat and eggs is achieved; and uncertainty or a cyclical risk caused by the consumption market of specialized laying chicken and meat chicken is avoided.

Description

technical field [0001] The invention relates to the technical field of poultry breeding methods, in particular to a method of using Babcock B380 to breed high-quality chickens with both colored feathers and eggs. Background technique [0002] Babcock B380 is a medium-sized high-yield laying hen bred by Isa company in France, without nesting ability. The weight at 140 days is about 1800 grams, the number of eggs produced at 300 days is 152, the weight at 300 days is 1900 g, and the number of eggs at 72 weeks is 325. At the same time, it also has other germplasm characteristics: 50% of commercial generations are white-tailed red feathers, 50% are black-tailed red feathers; 50% of commercial generations are fast-feather individuals, and 50% are slow-feather individuals. The above two characteristics facilitate the selection and breeding of target strains. [0003] Chinese people like to eat chicken. The food culture in this area has a long history. The consumption of chicken ...

Problems solved by technology

[0004] However, with the improvement of people's requirements for the quality of eggs and chicken, the existing specialized breeds of laying hens and broilers will be affected by the market's supply and demand for eggs and chicken, and there will be uncertain or periodic fluctuations. risk

And for breeding enterprises or farmers, this risk will undoubtedly cause economically uncertain losses, and how to combine laying hens and broiler hens to improve specialized broiler hens or laying hens in the existing technology, so as to While satisfying people's demand for high-quality eggs and chicken, it can also avoid the risk of uncertainty caused by marketization to farming enterprises or farmers. This has become a problem that the farming industry needs to face and solve urgently
