Abstract

The invention belongs to the technical field of poultry breeding, and relates to a method for cultivating a special male parent strain mainly used as yellow-feather broilers, which comprises the following steps of: 1, hybridizing to generate a F1 generation by taking a broiler chicken from another country as a male parent and a yellow-feather broiler with characteristics of jute feathers and yellow shins as a female parent, selecting and remaining F1-generation cocks and performing feeding and management according to a feeding and management method of breeding hens; 2, mating a F1-generation cock serving as the male parent with the female parent in the step 1 to generate a F2 generation, grouping respectively according to feather colors in the F2 generation, performing test cross, and performing the feeding and management according to the feeding and management method of the breeding hens; 3, crossing male and female individuals of each group obtained in the step 2 athwart and propagating, and purifying and fixing beneficial characters according to a family and individual selection method; and 4, breeding by four or more than four beneficial characters for generations to form a new broiler strain containing the bloodlines of the broiler chickens from other countries. By the method, the growth speed of the yellow-feather broilers in China is improved substantially, and the feed conversion rate is reduced.
