The method of using Babcock b380 to breed high-quality chickens with colored feathers and eggs

Abstract

The invention discloses a method of using Babcock B380 to cultivate high-quality chickens with both colored feathers and meat eggs, including: step 1, using the black-tailed fast-feather Babcock B380 heterozygous for the recessive white locus as the female parent, and the recessive white locus is used as the female parent. The colored feather local variety Kuaiyu individuals with sexual white feathers were used as the male parent to cross, and the white feathered Kuaiyu line was bred; step 2, the slow feather Babcock B380 with the wild-type homozygous recessive white locus was used as the female parent, and the recessive white locus was used as the female parent. The white gene locus is the wild-type homozygous slow-feather and colored-feather local variety as the male parent for crossing to breed the colored-feather slow-feather line; step 3, select the bred white-feather fast-feather line as the male parent, and the colored-feather slow-feather line as the female parent , Hybrid production of colored feather meat eggs and high-quality chicken commercial seedlings. Compared with the existing high-yielding laying hen breeding, this method speeds up the process, and the bred commercial seedlings can distinguish between male and female; compared with local breeds, the egg production is higher, the quality is better, and both meat and eggs are used, avoiding the problems brought by the specialized laying hen and broiler consumer market Uncertainty or cyclical risk.

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
