Method for breeding blue-lower-leg spotted-brown-feather laying hens with high egg yields

The invention discloses a method for breeding blue-lower-leg spotted-brown-feather laying hens with high egg yields. The method comprises the following steps of: artificially inseminating and mating a large quantity of Huainan spotted-brown cocks serving as male parents and Loman laying hens serving as female parents, collecting hatching eggs and hatching an F1 generation; identifying cocks and hens according to the colors of feathers and lower legs, eliminating white-feather yellow-lower-leg chicken which are cocks, reserving spotted-brown-feather blue-lower-leg chicken which are hens for serving as breeding hens, and performing back crossing by taking Huainan spotted-brown cocks as male parents to produce an F2 spotted-brown-feather generation; crossly mating and fixing the F2 generation and performing family breeding to produce an F3 generation; and performing gradual pure breeding on the F3 generation and later generations and obtaining the blue-lower-leg spotted-brown-feather laying hens with high egg yields according to egg yield, protein, lower leg color, feather color and bodily form, wherein the feathers are spotted-brown feathers; and the bodily form refers to delicate and pretty bodily form, blue lower leg and blue beak. According to the method, an appropriate high-egg-yield gene is introduced into a local chicken breed, and the proteins and macroscopic features of the local chicken breed are kept simultaneously.

Molecular genetic marker related with egg laying performance of hens and application

The invention provides a molecular genetic marker related with an egg laying performance of hens and application. An FSH (Follicle-Stimulating Hormone)-beta gene is used as the molecular genetic marker related with the egg laying performance of the hens; the molecular genetic marker is characterized in that the nucleotide sequence of the molecular genetic marker is shown as SEQ ID No. 1 or the sequence at least comprises a specific fragment of a 259 T>G mutated basic group. The egg laying performance of the hens are selected according to gene types and the molecular genetic marker has the characteristics of high accuracy, simplicity in operation and low cost (the selection cost is about 0.3 yuan per hen) and the like; automatic detection can be carried out; secondly, a molecular marking method provided by the invention can be used for selecting properties of the egg laying performance of the hens at an early life stage (within one week after chickens are hatched), the generation interval can be shortened, the selection intensity is improved and high-quality breeding hen parents can be selected relatively early, so that a breeding progress of the hens is accelerated; compared with a conventional determination selection method for the egg laying performance of the hens, the selection time of each generation can be shortened by 16 months.
