Problems solved by technology

However, at present, domestic hen species have a low egg production, resulting in a state in which the number of eggs is in short supply. Even if a large amount of feed is fed, it is difficult to increase the egg production, which shows that the current chickens have the disadvantage of insufficient nutrient conversion and absorption; the layer hen species that currently meet the market demand Many of them improve their production and reproductive performance through simple hybridization between several breeds, resulting in unstable quality and traits of commercial laying hens, especially the serious separation of traits such as feather color and shank color; low reproductive performance and low survival rate , the egg production rate of the group is not high, and the difference in growth rate and weight is relatively large; and with the rapid development of my country's social economy, the national poultry breeding technology has made rapid progress, and the production of the domestic laying hen market has undergone tremendous changes. The demand for the quality and appearance of eggs and chickens has also undergone major changes, and the pursuit of taste, health and safety

Embodiment

[0042] The Jianghan chicken and the Babcock chicken were crossed to obtain the D line, and the following closed family was selected for breeding, and the individual with high egg production was selected to form the first female parent.

[0043]That is, the offspring produced by crossing Jianghan chicken as the male parent and Babcock chicken as the female parent, and the offspring produced by Jianghan chicken as the female parent and Babcock chicken as the male parent, are cross-crossed, and then selected and bred to obtain the first A female parent.

[0044] The breeding of the first female parent includes the following procedures:

[0045] (1) Forming a family line: the maternal line is 1:10, the paternal line is 1:8, and each generation has 58 maternal lines and 57 paternal lines;

[0046] (2) Age selection: record the initial indicators, eliminate stunted and genetically defective individuals, keep all healthy female chicks that meet the requirements, and keep 40% of the ...

Abstract

The invention relates to a hybrid production method of high-egg-yield and grain-saving laying chickens. The hybrid production method comprises the following steps of (1) hybridizing Jianghan chickensand Babcock chickens to obtain D-line chickens, and breeding to form first female parents; (2) hybridizing Babonate Heikang chickens and Hongshan chickens to obtain C-line chickens, breeding, and selecting and remaining slow-feathering pure gene bodies to form first male parents; (3) hybridizing male parents of aulic yellow dwarf chickens and female parents of the Jianghan chickens to obtain E-line chickens, breeding, and selecting and remaining dwarf bodies with fast feathering and recessive white feathers to form terminal male parents; (4) hybridizing the first male parents and the first female parents to generate parent hens; (5) hybridizing the parent hens and the terminal male parents to obtain commercial chickens. The hybrid production method has the beneficial effects that the commercial chickens with good body type and appearance, stable breeding performance, high disease resistance, high survival rate and egg laying rate, early laying, excellent egg quality, grain-saving effect and mild temperament are obtained by selecting proper complete set lines.

Description

technical field [0001] The invention relates to a seed production method of high-yield and grain-saving laying hens, belonging to the field of poultry genetics and breeding. Background technique [0002] Eggs are rich in cholesterol and rich in nutrition. An egg weighs about 50 grams, contains 6-7 grams of protein and 5-6 grams of fat. The amino acid ratio of egg protein is very suitable for the physiological needs of the human body, easy to be absorbed by the body, the utilization rate is as high as 98%, and the nutritional value is very high. It is one of the foods that humans often eat. However, at present, domestic hen species have a low egg production, resulting in a state in which the number of eggs is in short supply. Even if a large amount of feed is fed, it is difficult to increase the egg production, which shows that the current chickens have the disadvantage of insufficient nutrient conversion and absorption; the layer hen species that currently meet the market de...
