Method for raising new strain of lean meat type Huai pigs

Abstract

A method for culturing a lean-type Huai pig includes such steps as crossing between the Huai sow as female parent and the Changbai boar as male parent to obtain the first generation sow group, crossing it with Yorke boar to obtain the zero-generation new variety and transverse crossing for 3-4 generations by selective group secondary culture molecular maker aided selection. The new variety features high port quality, rate of lean port and resistance to disease.

Description

technical field [0001] The invention relates to a breeding method of a new strain of pigs. Background technique [0002] After half a century of hard work in developed countries, through systematic breeding and combining ability testing under standardized feeding conditions, the production performance of commercial lean pigs has been improved to a great extent of genetic potential. The low quality of pork in developed countries is indeed a problem. Scientific research is also developing in the direction of improving pork quality, high-quality pork and organic pork that adapt to consumers' tastes. Jean NAVEAV of the French Academy of Sciences used Chinese Taihu pigs (Meishan pigs and Jiaxing black pigs) as female parents. After 8 years of research, they bred a new female line of "Grandma" and crossed it with the P76 male line. There is also PIC company, which also uses Taihu pigs for breeding The new female line "Campbell" was bred with high strength and good meat quality, ...

AI Technical Summary

Problems solved by technology

In fact, the existing domestic and foreign research on candidate genes for meat quality traits has the problem of relatively small and concentrated research.
