Embodiment

[0019] A seed production method of a grain-saving type Huiyang bearded chicken matching line:

[0020] Step 1. Hybridizing the hen of the bearded chicken slow-feather strain (C strain) and the dwarf yellow-feather broiler strain (Y strain) cock, and the dwarf three-yellow bearded hen produced is the parental female parent;

[0021] Step 2. The parental parent and the beard chicken fast-feather strain (D strain) are crossed to produce a medium-sized rooster with deep chest and wide back, well-developed chest muscles, plump hindquarters, thick and short beak, no wattles, and "yellow hair, yellow The three-yellow beard broiler chicken with the characteristics of "three yellow beards" with beard-like beard and feathers on the lower jaw is the food-saving Huiyang bearded chicken matching series commodity generation.

[0022] Compared with the beard chicken fast-feather strain (D strain), the average body weight of the 120-day-old male and female chickens produced by the seed produc...

Abstract

The invention belongs to the technical field of breeding industries, and relates to a poultry breeding technology. A matched hybrid production method for grain-saving type Huiyang beard chickens comprises the steps that hens of a Huiyang beard chicken slow-feather strain (C strain) are hybridized with cocks of a dwarf type yellow-feather broiler strain (Y strain), produced dwarf type three-yellow beard hens are female parents of a parent generation and then are hybridized with cocks of a Huiyang beard chicken fast-feather strain (D strain), and produced normal three-yellow beard broilers are a commodity generation. By the adoption of the matched hybrid production method for the grain-saving type Huiyang beard chickens, the produced commodity generation is the three-yellow beard broilers which are well-developed in chest muscle, fast in growth, strong in disease resistance and good in meat taste. Compared with the D strain, the average weight of 120-day-old cocks of the commodity generation and the average weight of 120-day-old hens of the commodity generation are increased by 316 g and 292 g respectively, the feed conversion ratio of the cocks and the feed conversion ratio of the hens are decreased by 0.62 and 0.53 respectively, the feeding cost is saved, and the breeding benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of breeding industry and relates to poultry breeding technology. Background technique [0002] With the improvement of people's living standards, the indicators of poultry products in aspects such as taste, flavor and safety are more and more valued by consumers. Local chicken breeds in my country have the characteristics of good meat quality, good flavor, and strong adaptability. Based on these excellent traits, my country's breeding experts have cultivated some local, high-quality matching breeds, such as Jinghai Yellow Chicken and Guangdong Qin Huang Chicken. Department, Wanjiang yellow chicken and Wanjiang Ma chicken matching department, etc. [0003] Matching line breeding, that is, according to the germplasm basis of variety resources and market demand, select individuals with the required traits to form a basic group, and use the method of inter-variety hybridization, intra-variety differentiation and...
