Abstract

The invention discloses a method for breeding a high quality chicken with a high feather fitness degree, belonging to the field of poultry genetic breeding and reproductive technology. The breeding method comprises the following steps that: after hatching cocks are detected, selected and remained according to the conventional strain standard, when the cocks are 150 to 170 days old, the length of a main wing which is the fifth from the axial feather to wing tips is measured, the individual cock whose wing is the shortest is selected and remained, and the selecting and remaining rate is 0.9% to 2.0%; after hatching hens are selected and remained after being detected according to the conventional strain standard, the one whose quality is the best is selected and remained, the selecting and remaining rate is 9% to 26%, the pedigree is established at the ratio of cocks to hens being 1:12 to1:16 so as to breed the next generation; and after breeding for at least two generations, the high quality chicken with high feather fitness degree can be obtained. According to the method provided by the invention, only the length of the fifth main wing is measured and screened, the fifth main wing is representative, the measurement workload is reduced, the measurement result is accurate, while the chicken with the feather fitness degree is bred, the other trait breeding is also seriously carried out, so that the overall performance of the product can be improved, and the bred chicken is more competitive on the market.

Description

technical field [0001] The invention relates to the technical field of poultry genetics, breeding and reproduction, in particular to a method for breeding high-quality chickens with high feather closeness in poultry breeding. Background technique [0002] In the current environment where domestic broiler sales are still dominated by feather chickens, the size and appearance of chickens still have a great influence on the selling price. Among them, the fit of feathers is a very important factor affecting the selling price and the difficulty of sales. Individuals with compact feathers are more popular with consumers. However, the feathers of some chickens on the market are poorly fitted, seriously affecting sales. Feather fit is a trait that is affected by many factors and is difficult to quantify. In breeding practice, there is a lack of a quantifiable, practical and effective breeding method for feather fit. Contents of the invention [0003] The object of the present i...
