Embodiment 1

[0013] Embodiment 1, a kind of breeding method of new line of high-yielding iron-footed hemp chicken, comprises the following steps:

[0014] a. Using Langshan hens with black and blue feather characteristics as the male parent, and green-shell laying hens with black feather characteristics as the female parent, crossbreed to produce the F1 generation, and select the F1 generation black feather hen;

[0015] B, do male parent with the male parent in the step a, produce F2 generation with F1 generation black feather hen, choose to stay in the hen with black feather, black shank feature in F2 generation;

[0016] c, with the green-shell laying hen with black feather feature as male parent, with the F2 generation black feather, black shank hen, produce F3 generation, choose and stay in the individual with black feather, black shank feature in the F3 generation;

[0017] d. Carry out cross-crossing and multiplication of the individuals obtained in step c, and breed a new line of h...

Abstract

The invention belongs to the technical field of poultry breeding, and particularly relates to a breeding method for a new strain of high-yield green-eggshell laying hens with relatively high egg laying performance. The method comprises the following steps: hybridizing Langshan chickens serving as a male parent and the green-eggshell laying hens serving as a female parent to generate a generation F1, selecting black-feather hens of the generation F1 for continuous hybridization with the male parent in the step a to generate a generation F2, selecting hens of the generation F2 for hybridization with the green-eggshell laying hens to obtain a generation F3, performing crossing and expanding propagation, and breeding the new strain of the high-yield green-eggshell laying hens after breeding of 3 generations. The new strain of high-yield green-eggshell laying hens are relatively high in egg yield; compared with the original female parent, the high-yield green-eggshell laying hens have the egg production week shortened by 2 weeks or longer, and the annual egg output is increased by 40 pieces or more.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for cultivating a new strain of high-yield green-shell layer hens with relatively excellent laying performance. Background technique [0002] Green-shell hens are named for their green-shell eggs. It is characterized by the green shell color of the eggs. It is a unique poultry species in my country. This chicken species has strong disease resistance and wide adaptability. Management, epidemic prevention and disease elimination are no different from ordinary chickens. Green-shell hens have special medicinal value. Some nutrients in the eggs, such as vitamin B1, B2, zinc, iodine, etc., are many times higher than ordinary eggs. With the improvement of people's living standards, consumers are getting more and more With more and more emphasis on the nutritional value of food, green-shell hens and the eggs they produce are becoming more and more popular wit...
