A method for rapid seed production of early-maturing and high-quality Sanhuang chickens

A three-yellow chicken and early-maturing technology, which is applied in animal husbandry and other fields, can solve problems such as unsatisfactory economic benefits, large coefficient of variation in body weight, and low egg production of hens, and achieve geographical distance and long kinship, early sexual maturity, and chick production. The effect of many

Abstract

The invention relates to a chicken breeding method, in particular to an early-maturing high-quality sanhuang chicken quick breeding method. According to the method, a Guangxi yellow chicken early-maturing strain serves as a male parent, a Jinghai yellow chicken serves as a female parent, and early-maturing high-quality sanhuang chickens are produced. The method has the advantages that (1) the Guangxi yellow chicken bred for two generations is selected, an early-maturity line is built to serve as the male parent, and breeding is quick; (2) the Guangxi sanhuang chicken early-maturity line serves as the male parent, the Jinghai yellow chicken serves as the female parent, the geographic distance is long and the genetic relationship is not close; (3) sexual maturity is early; (4) growing speed is high; (5) uniformity is high; (6) heterosis is obvious.

Description

technical field

[0001] The invention relates to a seed production method for chickens, in particular to a rapid seed production method for early-maturing high-quality three-yellow chickens. Background technique

[0002] Sanhuang chicken is characterized by yellow hair, yellow feet and yellow skin. Because of its tender meat, delicious taste and rich nutrition, it is very popular among Chinese consumers. At present, most of the Sanhuang chickens on the market are imitation soil Sanhuang chickens, which have introduced the blood of fast large or recessive white. The advantages are fast growth, resistance to rough feeding, and strong disease resistance. The disadvantages are late sexual maturity, large coefficient of variation in body weight, less egg production, variegated feathers, and unsatisfactory economic benefits.

[0003] There is a correlation between chicken sexual maturity and eating quality, and it is used as an indicator of sexual maturity in production to select ...

Examples

Embodiment 1

[0018] (1) Select 40 roosters with a comb height of more than 2 cm in the 42-day-old Guangxi Sanhuang chicken, and 400 hens with a comb height of more than 0.5 cm, as the basic group, and establish a pedigree record file;

[0019] (2) Self-propagation of male and female chickens, using individual selection and family selection methods, 42-day-old roosters with a comb height of less than 2.3 cm and hens with a comb height of less than 0.6 cm were eliminated. When the hens were raised to 30 weeks of age (the peak egg production period), they were bred according to the male-to-female ratio of 1:10, and the pedigree was hatched, and 3540 offspring mixed male and female chicks were obtained as the first generation, and a pedigree record file was established;

[0020] (3) Carry out family selection for the first generation to improve uniformity and precociousness;

[0021] (4) Steps (2) and (3) were repeated to cultivate a precocious line of Guangxi Sanhuang chickens, including 110 ...
