Chicken skin yellowness breeding method

Abstract

The invention discloses a chicken skin yellowness breeding method. The method comprises the following steps: 1) determining cloaca skin color yellowness, chicken serum xanthophyll concentration and chicken serum beta-carotene concentration of a chicken to be detected; 2) solving a yellow skin breeding value according to a formula S = 0.5 * [B + (5 * C)] + 0.5 * (50 * A); and 3) retaining the to-be-detected chicken with the S value greater than 600. According to the chicken skin yellowness value breeding method, the two methods of detecting the skin yellowness value through the colorimeter and detecting the serum yellow pigment concentration value through the liquid chromatograph are adopted to cooperatively select the chickens with the high skin yellowness value and the low skin yellowness value, then large-scale breeding is conducted, the influence of the external environment on the skin yellowness value is reduced, the skin color is yellow and uniform, and market requirements are met.

Description

technical field [0001] The invention relates to the technical field of chicken breeding, in particular to a chicken skin yellowness breeding method. Background technique [0002] The poultry industry is an important part of animal husbandry, and poultry meat and eggs are an important source of protein in the human diet. Color traits are important phenotypes of animals, which can affect the mating, adaptation and communication of animals, and can reflect the health status of animals. Under market conditions where chilled chickens are becoming more and more popular, skin color is the first intuitive impression presented to consumers by broiler chickens. The depth and uniformity of skin color have become important features that determine consumer acceptance and broiler quality. Affected by eating habits, consumers in South China are more inclined to choose chickens with yellower skin, brighter skin and uniform color. Chickens with pale or uneven skin are sold at a lower price...
