Problems solved by technology

However, the sources of small white-feathered broiler chickens currently on the market are mixed. They mainly use fast and large white-feathered broiler chickens and high-yielding layer hens for simple economic hybrid breeding, without targeted systematic breeding and hybrid matching. Combination test, low production efficiency, irregular seed production
Marketed commercial broilers generally have the disadvantages of poor disease resistance, low uniformity, and low meat yield

Embodiment 1

[0031] The three-line supporting seed production process of embodiment 1 small-sized white-feathered broiler

[0032] The Beijing Institute of Animal Husbandry and Veterinary Medicine of the Chinese Academy of Agricultural Sciences has implemented the three-line matching seed production of small white-feathered broilers. Concrete cultivation method comprises the following steps:

[0033] (1) Crossbreed the egg-type Luodao red male parent and Luodao white female parent (the male parent of Luodao red used in this example is single-crown), use closed-line family selection, and select individuals with fast feathers and silver feathers , forming the first female parent whose genotype is ♀ Z (kS) W;

[0034] There are more than 3,000 seeds in each generation. This strain has high reproductive performance. The weight of adult hens is 1750g-1900g, and the weight of adult roosters is 2300g±10g. The average number of eggs laid by each hen is 255 in 66 weeks.

[0035] (2) Using dom...

Abstract

The invention discloses a small rkatsiteli fryer three-line matched seed production method, which comprises the following steps: (1) hybride the egg-type Rhode Island red male parent with the Rhode Island white female parent and raise by atresia pedigree to select the individuals that have fast feather and silver feather as the first female parent, and the genotype is shown in the description male Z(ks)Z(ks), female Z(ks)W; (2) take domestic or local kind as the material and raise by atresia pedigree to form a first male parent that has a slow feather and takes the gold feather gene, wherein the genotype is shown in the description male Z(Ks)Z(Ks), female Z(Ks)W; (3) takes the introduced fast-feather rkatsiteli broiler breeder as the final male parent that is shown in the description male Z(k)Z(k), female Z(k)W; (4) hybride the first male parent and the first female parent to generate F1 generation hen, then hybride the F1 generation hen with the final male parent to get the small rkatsiteli fryer. The small rkatsiteli fryer parents generation chicken can provide a lot chicks in low cost, and the goods generation chicken have a strong disease resistance and a significant integrated benefit.

Description

technical field [0001] The invention belongs to the field of poultry genetics and breeding, and relates to a three-line matching seed production method for small white-feathered broilers. Background technique [0002] my country's commercial broiler breeds mainly include white-feather broiler, yellow-feather broiler and small white-feather broiler (also known as 817 broiler). Compared with white-feather broilers and yellow-feather broilers, small-scale white-feather broilers have the advantages of smaller market weight, suitable for deep processing of whole chickens, moderate meat quality, and cheap chicks. The market consumption is gradually increasing, with about 800 million listings per year, accounting for about About 10% of the broiler market slaughter. However, the sources of small white-feathered broiler chickens currently on the market are mixed. They mainly use fast and large white-feathered broiler chickens and high-yielding layer hens for simple economic hybrid b...
