Embodiment 1

[0023] The present embodiment has cultivated a kind of slaughter type ephedra broiler new breed, and concrete process is:

[0024] (1) Breeding of the pure line Y1 of yellow chickens: Shiqi mixed chickens are used as the zero generation, and the cocks and hens of the zero generation are freely mated. At the age of 6 weeks, a hen with a moderate body size and a body weight of 700-840g is selected. And roosters with a body weight of 800-940g, individual characteristics of yellow feathers, slow feathers, yellow shanks, and yellow beak. At 20 weeks of age, the muscles are full, the body weight is 1780-2000g, the shank length is ≤ 6.0cm, and the shank circumference is 4.5-5.3cm. Hens with a body weight of 2980-3120g, shin length 7.0-7.8cm, shin girth ≥ 5.6cm, at the age of 46 weeks, select individuals with a peak egg production rate greater than 86% as the first generation; Individuals are cross-crossed and multiplied, and the offspring individuals are selected as the second genera...

Abstract

The invention discloses a slaughter type spotted-brown broiler chicken specialized strain breeding method which comprises the following steps of firstly, establishing three specialized strains: a yellow chicken pure line Y1 with medium and fast growth speed and high laying rate, a spotted-brown chicken pure line M1 with medium and slow growth speed and high laying rate, and a fast large spotted-brown chicken pure line M2 with medium and slightly fast growth speed; taking the bred yellow chicken pure line Y1 as a first female parent, taking the bred spotted-brown chicken pure line M1 as a first male parent, and hybridizing to obtain a terminal female parent F1; and finally, hybridizing the bred spotted-brown chicken pure line M2 serving as a terminal male parent with the terminal female parent F1 to obtain a commercial generation of slaughter type spotted-brown chickens. According to the slaughter type spotted-brown broiler chicken specialized strain breeding method provided by the invention, the slaughter type spotted-brown broiler chicken has fine carcass pores, remarkable double-chest characteristics, good meat quality, excellent chicken flavor and suitability for slaughtering and processing, the slaughtering rate is larger than or equal to 91 percent, and chilled transportation has small influence on the meat quality and the flavor.

Description

technical field [0001] The invention belongs to poultry genetics and breeding, in particular to a breeding method for slaughter-type ephedra broiler mating lines. Background technique [0002] Affected by food safety, sales of live poultry are gradually tightened in many regions. In the future, live poultry trading will face more uncertainties, and the market will gradually change from live poultry trading to chilled chicken. After chilled broiler chickens are launched on the market, the judging criteria for chicken quality are mainly the carcass traits of the chickens. Chilled chickens with high leg ratio, fine pores, and good skin firmness are more favored by consumers. At present, the mainstream broiler breed that is chilled and marketed is white-feather broiler, which has poor meat quality and flavor, and does not meet the quality requirements of Guangdong, Guangxi, Hong Kong and Macao markets. Therefore, in view of the regional market's preference for chilled chicken, ...
