Problems solved by technology

It solves the disadvantage that the eggs produced by other hybridization methods are relatively heavy and easy to be confused with duck eggs. The color of the green-shell eggs is pure, which solves the problem of mixed egg colors and has good marketing value.

Embodiment

[0012] For the method of obtaining commercial offspring of green-shell layer hens, three hybridization methods are now provided:

[0013] The first matching line: the commercial generation obtained by crossing black-feathered green-shell layer roosters and sea-blue brown-shell layer hens;

[0014] The second matching line: the commercial generation obtained from the crossbreeding of red-feathered green-shell layer roosters and sea-blue pink-shell layer hens;

[0015] The third matching line: the hybridization method adopted in the present invention, the commercial generation obtained by crossing a red-feathered green-shell laying hen rooster and a Nick coral pink laying hen hen.

[0016] The above three matching lines were reared in the same feeding environment at the same time, and the age at first laying, body weight at 45 weeks, egg weight at 45 weeks, number of eggs at 72 weeks, stocking rate at 72 weeks, and green shell ratio were recorded separately. As shown in Table 1...

Abstract

The invention discloses a production method of high-yield blue-shell laying hens. According to the method, a red-feather green-shell laying hen, which is small in size and low in material consumption, serve as a cock, a high-yield white-feather Nick coral powder laying hen, which is small in size and low in material consumption, serves as a hen, and the two kinds of laying hens are in hybridization to obtain the high-yield blue-shell chicken. Compared with prior art, the laying hen produced by the method provided by the invention has the advantages of early age at first egg, small size, light egg weight, high egg production and blue-shell ratio, strong disease resistance, and has a popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a method for producing high-yield green-shell laying hens. Background technique [0002] Green-shell layer hens are firm and compact, with delicious meat and mellow soup, which is a good nutrition. The green-shell eggs produced contain a large amount of lecithin, vitamins, amino acids, and the content of trace elements such as selenium, iodine, iron, and zinc is 5 to 10 times higher than that of ordinary eggs. It belongs to high vitamins, high trace elements, high amino acids, and low cholesterol. , low-fat ideal natural health food. [0003] At present, the production methods of green-shell hens mostly adopt purebred green-shell hens for mating production, which has low egg production, irregular egg shape and low disease resistance. Due to the increasing market demand, many hybrid green-shell hens have emerged. The more common ones include using black-feat...
