Embodiment 1

[0049] The breeding method of embodiment 1 red-feathered white-shell hen mating line

[0050] 1. Establishment of paternal group

[0051] The male parent lineage in the mating line comes from single-crested white legion chickens, and the male parent group is bred by the following methods:

[0052] Using 600 single-crested white Laihang strains as female parents, crossed with 60 Chinese local bantam roosters, a few red-feathered individuals appeared in the offspring population; The red feather individuals in the offspring were crossed with Bai Laihang again, and this was done for at least 3 generations. Collect the obtained red feather individuals to form a basic group. Select 50 red-feathered roosters and 500 red-feathered hens, establish families according to the male-to-female ratio of 1:10, and establish a total of 50 families for mating expansion and breeding improvement. Constantly eliminate the non-red feather individuals in the offspring, purify and fix the red feath...

Abstract

The invention relates to a breeding production method for a synthetic line of a red-feather and white-shell-egg laying chicken. The breeding production method comprises the following steps: with a red-feather and white-shell-egg laying chicken obtained by hybridization and breeding of a white-leghorn chicken and a bantam chicken as a male parent of the synthetic line, and the white-leghorn chickenwith an invalid dominant white I gene as a female parent, allowing the male parent to hybridize with the female parent so as to obtain a commercial-generation breeding egg, after the commercial-generation breeding egg is hatched, identifying female and male of a chick according to the color of feather, wherein a red-feather chick is female, and a white-feather chick is male, and selecting the red-feather female chick for feeding so as to obtain a commercial-generation laying chicken which has a red-feather body and can lay a white-shell egg. The breeding production method for the synthetic line provided by the invention has the following advantages: female and male of the chick can be identified according to the color of the feather and without the need of turning an anus, so the cost ofbreeding is greatly saved; and the red-feather and white-shell-egg laying chicken bred by using the method provided by the invention fills market vacancy, enriches the synthetic line of a laying chicken, has high growth and egg-laying performances, meets the requirements of farmers and food-processing enterprises for appearances and performances of chicken eggs and chickens, and has great market potential.

Description

technical field [0001] The invention relates to the field of livestock and poultry genetics and breeding, in particular to a seed production method of a matching line of red-feathered and white-shell laying hens. Background technique [0002] Eggs and chicken are high-quality and cheap food raw materials, which are widely used in food processing and catering industry. my country has a vast territory, various customs and habits, and different preferences for the appearance of chickens and eggs. Therefore, cultivating unique matching lines can better meet the diverse needs of the market. In southern China, consumers prefer chickens with red feathers, and every catty of chickens eliminated can realize an additional value of 2 yuan, so farmers prefer to raise chickens with red feathers. For food processing enterprises, compared with brown-shell eggs, they are more inclined to purchase white-shell eggs with smaller egg weights. Taking the number of eggs as the unit of measuremen...
