Black peritoneal phenotype determination method for early-stage selection of chickens and application of method

Abstract

The invention discloses a black peritoneal phenotype determination method for early-stage selection of chickens and application of the method. The method comprises the following steps of (1) pluckingclothing hair of an abdomen region which has a thinner skin layer, is not shielded by an muscle layer obviously and comprises ribs at two sides and the last rib and the edge of the pubis from the tailend of a keel to the underside of the anus of a chicken at 3 to 6 weeks, and taking the abdomen region as a determination region; and (2) observing the determination region, and judging a chicken peritoneal melanin deposition degree phenotype according to a chicken peritoneal melanin deposition condition, wherein the chicken peritoneal melanin deposition condition is divided into four levels from0 to 3. According to the method disclosed by the invention, the peritoneal melanin deposition degree phenotype of the early-stage live chicken group can be determined and selecting and remaining arecarried out, so that a purpose of reducing the ratio of the black peritoneal phenotype of the chicken group at the offering day is achieved, a necessary method is provided for early-stage breeding work of the carcass traits of the broilers, the breeding cost can be saved, and the economic benefit can be improved.

Description

technical field [0001] The invention relates to the technical field of poultry breeding and breeding, in particular to a black peritoneal phenotype determination method for chicken early selection and application thereof. Background technique [0002] In my country, broiler chicken production is dominated by white-feather broiler chickens and yellow-feather broiler chickens. After more than 20 years of development, yellow-feather broiler chickens have now occupied nearly half of my country's broiler chicken market, and are varieties with independent intellectual property rights in my country. [0003] In recent years, incidents of human infection with H7N9 influenza have occurred from time to time, causing heavy losses to the yellow-feather broiler industry that relies heavily on live poultry trading, exposing the shortcomings of the traditional live poultry trading model, forcing industrial transformation, and objectively promoting the yellow-feather broiler industry. The p...
