[0056] Example:

[0057] Through the determination of combining ability of binary and ternary crosses of Huai pig (Dingyuan pig) and exotic breeds (Dan line Landrace pig, Jia line York pig and Taiwan line Duroc pig) × fixed, du × fixed and du × long × fixed, big × long × fixed, du × big × fixed, long × big × fixed, big × du × fixed, long × du × fixed (definitely is a designated far pig, long It refers to Dan Landrace pigs, Da refers to York pigs of the plus line, and Du refers to the Duroc pigs of the Taiwan line). From the characteristics of the pig's coat color, litter size, growth performance and meat quality, after measurement and analysis, the length × is determined as The best combination for the production of binary hybrid pigs, large × long × is determined as the best combination for the production of ternary hybrid pigs. Based on this ternary hybrid pig, the zero generation of the new line is formed. After 3-4 generations of selection and breeding, a new line of high...

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, ...
