Abstract

The invention discloses a method for increasing the Puan mountain Miao black-bone chicken laying rate. The method comprises the step that locally-proliferated black-bone hens and cocks in the Puan county of the Guizhou province and locally-naturalized Loman laying hens in the Puan county are subjected to hybridization on the basis of the combination of two-way cross, backcross, crossing fixation, local hybridization and artificial insemination methods by adopting the principle of animal genetics, good mountain Miao black-bone chicken are obtained, the phenomena that anciently-proliferated mountain Miao black-bone chicken in the Puan county of the Guizhou province are late in sexual maturity, high in broodiness and low in egg laying rate are effectively solved, the laying rate of Puan mountain Miao black-bone chicken can be greatly increased, and meanwhile the advantages that the Puan mountain Miao black-bone chicken are resistant to crude feed, strong in adaptability and disease resistance, delicious in taste, rich in fragrance, compact and tender in meat quality and the like are ensured.
