Abstract

The invention relates to the field of poultry breeding, in particular to a cultivating method of Jinling broiler. The method includes the steps of 1, subjecting dwarf spotty chicken to selfing, crossing fixation and breeding to obtain first male parents; subjecting grain-saving yellow chicken to selfing, crossing fixation and breeding to first female parents; 2, subjecting the first male parents and the first female parents to hybridizing, crossing fixation and breeding to obtain second female parents; subjecting fast-growth spotty chicken to selfing, crossing fixation and breeding to obtain second male parents; 3, subjecting the second male parents and the second female parents to hybridizing, and performing closed breeding for at least six generations to obtain the Jinling broiler. The Jinling broiler cultivated by the cultivating method has short feet, eats fewer grains, grows fast, has good disease resistance and has high chicken and egg nutritional value.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a method for cultivating Jinling chicken. Background technique [0002] Chicken is the most common poultry raised by humans. Chicken meat is tender and nutritious, and it is an indispensable ingredient on the table. However, most of the broilers currently on the market have slow growth rates, large grain consumption, and poor disease resistance, which cannot meet the growing needs of people.
