Hybrid species production method for yellow-foot local chickens

Abstract

The invention discloses a hybrid species production method for yellow-foot local chickens. The method is characterized by comprising the following steps: selecting Wenchang chicken protospecies with yellow feet and ephedra feathers, breeding the protospecies, taking healthy cocks in offsprings as a male parent, selecting sanhuang chicken protospecies with yellow feet and ephedra feathers in the southern Anhui, breeding the protospecies, taking healthy hens in offsprings as a female parent, and conducting hybridization on the male parent and the female parent to obtain commodity chickens. The method has the advantages that the feet of the commodity chickens are yellow, the shank length and the shank circumference are medium, the ephedra feathers are obtained, the body is compact, the appearances of the chickens conform to most market requirements in China, the viability of the commodity chickens is strong, the death and culling rate is low, the growth speed is high, the weight is good in uniformity, the commodity chickens are not suitable for being used as parents, a species manufacturer can control and protect a species source, and the species production method is further beneficial to promoting development and utilization of local excellent chicken species resources.

Description

technical field [0001] The invention relates to a seed production method, in particular to a yellow-footed chicken hybrid seed production method. Background technique [0002] China is the second largest broiler chicken breeding country in the world. With the improvement of people's living standards, consumers' choices of broiler chicken types are constantly changing. Compared with fast and large white-feathered broilers and fast yellow-feathered broilers, local native chickens in my country have outstanding advantages in appearance, meat quality, and flavor. Therefore, the consumer market for native chickens is getting bigger and bigger, and currently accounts for about 15% of the total broiler chickens in my country. %about. [0003] There are mainly two types of native chickens in my country, yellow feet and green feet. Most of the yellow feet native chickens have yellow feathers or ephedra feathers. They have traditional colors and body shapes that Chinese residents love...

AI Technical Summary

Problems solved by technology

However, most local chicken breeds in my country lack systematic breeding, self-propagation and self-raising seed production models are common, and the inbreeding coefficient of breeds is high, resulting in reduced viability of chickens, high mortality rate, slow growth rate, and uniformity. Difference

More importantly, the commercial generation chickens obtained from single-breed production are the same as the breeder chickens, and the sale of commercial generation chickens is equal to the sale of the original breed, resulting in a loss of control over the provenance
