Quick balanced breeding method of chicken breeds with high quality

Abstract

The invention discloses a quick balanced breeding method of chicken breeds with high quality, and belongs to the technical field of poultry breeding. The method comprises the steps of crossing meat chicken cultivated including 50% of blood relationship of local chicken and meat chicken including 75% of blood relationship of the local chicken in a supporting way to obtain a meat chicken breeding series including 62.5% of blood relationship of the local chicken. The external blood relationship content proportion of the local chicken and fast-growing chicken of the breeding series can well balance the negative correlation of inheritance between the meat quality and the growing speed, the inherit meat quality and flavor of the local chicken can be kept maximally when the growing speed can be improved, and the optimized high yield and high quality can be realized; furthermore, either progenitor male parent or female parent pure line of the combination of foreign varieties can be introduced by importing the foreign blood relationship, so as to reduce the determination on combining ability, and accelerate the homozygosis of genotype; in addition, an auxiliary selecting technology of a molecular marker is adopted to develop early selection, therefore the generation interval can be shortened, and the breeding progress can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of poultry seed production, and in particular relates to a rapid and balanced breeding method for high-quality chicken varieties. Background technique [0002] For nearly half a century, with the continuous progress of poultry genetic improvement and feed nutrition research, the poultry industry has made great progress. The accelerated growth rate of broilers and the improved feed conversion rate have made chicken the second largest meat consumption product after pork in China. However, with the gradual improvement of people's living standards, consumers' demand for meat is no longer limited to quantity, but higher requirements are put forward for the sensory, tenderness and flavor of chicken. How to solve the outstanding contradiction between the improvement of yield and the decline of meat quality has become a practical problem to be solved urgently in front of the majority of breeders.
