Abstract

The invention provides a novel black-bone chicken breeding method. The method includes the following steps of firstly, selecting Nanjing black chickens; secondly, with mountain black-bone chickens as the male parent, conducting hybridization between the mountain black-bone chickens and the Nanjing black chickens and between the mountain black-bone chickens and Daheng 699 broiler chickens to obtain the offspring group series B1 and the offspring group series B2; thirdly, conducting forward hybridization and backward hybridization between the series B1 and the series B2 to obtain the offspring group C and the offspring group D; fourthly, conducting hybridization between the group C and the group D to obtain the first generation of black-bone chickens, and conducting pure line breeding through the family method of breeding to obtain F1; fifthly, conducting hybridization between a group A and the F1 to obtain a group E; sixthly, conducting hybridization between a group B with the F1 to obtain a group F; seventhly, conducting hybridization between the group E and the group F1 to obtain a group F2, then conducting crossing fixation, and conducting pure line breeding through the family method of breeding to obtain novel black-bone chickens. The novel black-bone chickens are high in growth speed, vital force, laying rate and nutritive value, excellent in taste, flavor and nourishing effect, and suitable for being bred and popularized on a large scale.
