Problems solved by technology

At present, when the meat duck reaches the market weight, the breeding of duck plumage traits has not yet been carried out. It is particularly urgent to establish a new type of duck breeding method for the breeding of high-quality meat ducks, which will improve the uneven development of duck feather plumage. , it is of great scientific and practical significance to improve the processing level of meat duck carcasses and to expand the breeding methods

Abstract

The invention discloses a breeding method capable of improving performance of duck calamus. The breeding method includes the steps of (1), selecting young male ducks and young female ducks and feeding the young ducks for 63-68 days; (2), selecting male ducks of the weight meeting the on-marketing requirements, observing the contour feathers of the male ducks, grading calamus of each contour feather, and reserving the male ducks with the contour feather scores meeting breeding standards as breeding ducks, selecting female ducks of the weight meeting the on-marketing requirements, observing the contour feathers of the male ducks, grading calamus of each contour feather, and reserving the female ducks with the counter feather scores meeting breeding standards as breeding ducks; (3) building family of the reserved breeding male ducks and the female ducks according to the ratio of 1: 8-1: 10 to perform pedigree incubation to breed the next generation; (4) repeating the steps (1), (2) and (3) to perform breeding of at least three generations. The breeding method has remarkable effect of improving the performance of duck calamus, facilitates butchering and processing in scale and enables the butchered ducks to look neat.

Description

technical field [0001] The invention relates to the technical field of poultry genetic breeding and reproduction, in particular to a breeding method for improving the performance of duck tubes. Background technique [0002] In daily consumption, people are usually accustomed to observing duck back feathers to indirectly determine the quality and age of meat ducks. The uniformity of plumage development of marketed meat ducks directly affects the appearance of the carcass after slaughter and the price of meat ducks. The maturity of duck feathers includes multiple traits, and the duct (also known as dry hair) is one of the important indicators for judging the maturity of duck feathers. [0003] The growth and development of feathers are affected by many factors. "Tubes" are the feather characteristics of high-quality meat ducks when the body feathers mature. Related, is a very complex genetic and physiological phenomenon, involving many influencing factors. The color of the f...
