Embodiment

[0032] Supporting line female parent - the cultivation of high-yield black feather green-shell hen strain, the specific cultivation process is as follows:

[0033] (1) Using Heiyu Dongxiang green-shell layer hens and white Laihang hens as breeding materials, according to egg production records, select black-feather Dongxiang green-shell layer roosters and white Laihang hens about 210 days old, with a weight of 1.6-1.8 kg, the weight of the hen is 1.5-1.6 kg, and the F1 generation is crossed to obtain the F2 generation population.

[0034] (2) select and stay the black-feathered cock in the F2 generation group and black-feather, produce the green shell egg hen to mate, form the F3 generation group;

[0035] (3) Select black-feathered roosters and black-feathered, green-shell egg-laying hens from the F3 generation population, use yellow-feathered, pink-shell egg-laying local chicken breeds for test crossing, and select homozygous black-feathered green-shell egg-laying males and ...

Abstract

The invention discloses a method for cultivating grain-saving black-feathered green-shell hens, which specifically comprises the cultivation of high-yield black-feathered green-shell hens and the cultivation of grain-saving black-feathered green-shell hens. The present invention combines the knowledge of genetics to give full play to the genetic effects of dw genetic linkage, black feather and green shell genes, and uses the cultivated high-yielding green-shell hens as the female parent and the green-footed dwarf laying hens as the male parent to cultivate a grain-saving Type black-feathered green-shell layer hens, commercial chickens have good appearance, less material consumption, high egg production rate, and 100% green shell rate.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for cultivating grain-saving black-feathered green-shell laying hens. Background technique [0002] my country is a multi-ethnic country.
