Problems solved by technology

However, this kind of direct hybrid seed production has the following disadvantages: (1) It is impossible to select and breed the female parent, so the task of breeding the matching line can only be concentrated on the male line, and the progress of breeding is limited; (2) The size of commercial laying hens Too large lead to an average egg weight of 50-54g, especially after the age of 45 weeks, the egg weight is more than 55g, exceeding the weight standard of native eggs, which is not conducive to brand sales; (3) Improper selection of male parent species will affect eggshell (4) The body weight and egg weight uniformity of commercial laying hens are poor, and the products are not neat

Embodiment Construction

[0014] The breeding of F line and M line and the matching hybridization test are examples to set forth the method of the present invention below:

[0015] See attached figure 1 Cultivation of F line: using 40 imperial concubine chickens Artificial insemination with mixed semen of 600 Roman layer hens (♀) parents, 3058 eggs were collected, 1184 female chicks were obtained by machine hatching, and they were reared conventionally. When the hens are raised to 30 weeks of age (the peak egg production period), 80 chaise hens will be used According to the male-to-female ratio of 1:10, the family was bred, and the pedigree was hatched, and 7840 male-female mixed chicks were obtained as the basic group, and the pedigree record file was established. The basic group was selected and bred for 4 consecutive generations, and the F line was bred. See Table 1 and Table 2 for the selection pressure of each trait in each generation and the breeding progress of main traits, respectively.

Abstract

The present invention relates to poultry breeding technology, in particular to a method for cultivating soil breed laying hens. The method includes: F-line cultivation: use the synthetic line of the parental generation of the Guifei hen and the Roman laying hen to backcross with the Guifei hen to obtain 75% Guifei hen The basic group strains of chicken blood, and then carry out four consecutive generations of breeding; M line breeding: use the parental generation of Guifei chickens and Roman layer hens to obtain the basic group strains containing 50% of the blood of Guifei chickens, and then carry out four consecutive generations of breeding Breeding; supporting line production of commercial generation: the F line is used as the parent generation male parent, the M line is the parent generation female parent, the hybrid offspring obtained are sexed by the anus turning method, and the female chick is the commercial generation layer hen. The method can cultivate new breeds (matching lines) of soil-breed laying hens.

Description

【Technical field】 [0001] The invention relates to poultry breeding technology, in particular to a method for cultivating soil breed laying hens. 【Background technique】 [0002] Compared with eggs produced by foreign high-yield laying hen breeds (commonly known as "foreign eggs"), native eggs or imitation native eggs containing the blood of local chicken breeds are very popular among Chinese consumers for their beautiful appearance and excellent quality. With the rapid improvement of the living standards of urban and rural residents in our country, consumers have higher and higher requirements for egg quality, and breeding companies and farmers have an urgent demand for high-yielding soil-breed layer breeds. At present, most laying hen production enterprises use local chicken breeds to directly crossbreed with foreign high-yielding laying hen female parents, and the offspring are raised as local commercial laying hens, and the egg production performance has been greatly impro...
