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.
