A kind of cultivation method of black feather powder shell layer hen

Abstract

The invention discloses a method for cultivating black-feathered powder-shell hens. The cultivation is carried out through the following steps: (1) selecting brown-shell laying hens great-grandfather line A cocks, brown-shell laying hens great-grandfather line B cocks, and brown-shell laying hens The male parent of A-line cock, brown-shell layer hen ancestor B-line rooster or AB-line cock of brown-shell layer parent is used as the male parent, and the semen is extracted artificially; (2) The imperial concubine hen is selected as the female parent for artificial insemination (3) Collect the breeding eggs produced by the hen of the imperial concubine chicken 2 days after fertilization, and hatch; (4) The hatched hen is the black feather powder shell hen. The body shape, weight and appearance of the black-feathered powder-shell hens cultivated by the invention are similar to those of native chickens, the feather color is black feathers, and the egg-laying performance is excellent. The weight is about 50g. The black-feather powder-shell hens can be raised in cages or free range. The price of the eliminated chickens is high, and it is suitable for large-scale breeding.

Description

technical field

[0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for cultivating black-feather powder-shell laying hens. Background technique

[0002] China's traditional food culture has a very important influence on the food structure. Food consumption not only pays attention to nutrition and flavor, but also has high requirements on the appearance of food. Eggs are one of the important animal protein sources for people’s daily consumption. With the development of the economy and the improvement of living conditions, consumers’ requirements for the quality of eggs are also gradually increasing. Especially in recent years, the market demand for native eggs has continued to expand. Profits also attract more farmers. However, due to the poor egg-laying performance of native chickens, in general, the maximum number of eggs laid per year is no more than 180, which affects the industrialization of native chickens. ...
