Example Embodiment

[0026] Hereinafter, the present invention will be further described in detail and completely with reference to the embodiments, but it is only an exemplary description of the present invention and is not a limitation on the scope of the present invention.

[0027] 1. Selection of male parent and female parent

[0028] In the matching line, the male parent adopts the fast-feathering line of royal chickens. It is necessary to check the typical characteristics of the royal chickens at the age of 1 day after hatching, and make a selection: that is, eliminate four-toed chickens and keep five-toed chickens; eliminate non-crested chicks and keep them Crested chicks; check and select the feathering speed at the same time, weed out slow-feathering chicks, and only use chicks with obvious fast-feathering for the breeding of male parent chicken lines in this method. And weed out weak chicks and keep healthy chicks.

[0029] Male parent selection mainly selects individuals and families with the...

Abstract

The invention relates to the technology of poultry breeding, and discloses a hybrid breed production mode of a black feather chicken commercial line. The hybrid breed production mode can be used for producing black feather chickens in a scale mode, and comprises the steps that (1) a male parent and a female parent are selected and bred, wherein in the commercial line, a princess chicken of a fast feather strain is adopted as the male parent, and a rhode island red chicken of a slow feather strain is adopted as the female parent; (2) hybrid breed production of the commercial line is carried out, wherein the male parent and female parent screened and bred through the method are hybridized, and commodity generation hatching eggs are obtained. In the hybrid breed production mode, the male parent and female parent are not black feather chickens, and obtained commodity generation chickens are small black feather chickens; commodity generation egg chickens produce eggs with pink shells. The black feather chickens produced through the hybrid breed production mode are good in body form, high in laying rate, good in egg shell quality and high in disease resisting capacity.

Description

technical field [0001] The invention belongs to the technical field of breeding industry, relates to poultry breeding technology, in particular to a seed production method of a mating line of black-feathered chicken. Background technique [0002] Breeding of chicken mating lines is the main form of modern chicken breeding system, that is, through the hybridization of different chicken strains and their fixed breeding patterns, large-scale production of hybrid offspring, which will be fed as end products (commercial generations) and supplied to the consumer market . Matching line seed production can quickly transfer excellent genetic genes from breeding farms to terminal commercial farms on a large scale. This kind of mating line seed production mode is not only of great significance in meeting the social demand for chickens, but also can obtain commercial benefits. The evaluation of the pros and cons of the supporting system is mainly based on whether the supporting system...
