Breeding method for producing high-quality synthetic-line commercial pigs by utilizing Luchuan pigs

Abstract

The invention discloses a breeding method for producing high-quality synthetic-line commercial pigs by utilizing Luchuan pigs. The breeding method includes that male parents selected from large white pigs hybridize with female parents which are also selected from the large white pigs, and high-quality large white male pigs are selected from the produced hybrid generations to serve as final male parent breeds; the local Luchuan pigs are selected as female parents of the synthetic-line pig parent generation and hybridize with landrace serving as the male parents of the synthetic-line pig parent generation, and high-quality female Changlu pigs are selected from the produced hybrid generations to serve as female parent breeds; the selected male parents and the selected female parents are subjected to hybridization, and the hybrid generations serve as the high-quality synthetic-line commercial pigs which are then put into production. The breeding method for producing the high-quality commercial-line commercial pigs by utilizing the Luchuan pigs has the advantages that the high-quality local pig breeds, namely the Luchuan pigs, of Guangxi are utilized for breeding a special strain of the Luchuan pigs, and the large white pigs, the landrace and the Luchuan pigs are subjected to three way hybridization to form a complete set for producing high-quality commercial pork pigs, wherein the Luchuan pigs serve as the female parents in the synthetic-line pig parent generation, the landrace serves as the male parents in the synthetic-line pig parent generation, the Changlu female parent pigs are obtained by means of hybridization, and the large white pigs serving as the synthetic-line final male parents hybridize with the Chuanglu female parent pigs so as to produce high-quality Landrace Luchuan commercial pigs.

Description

technical field [0001] The invention relates to the field of animal breeding, in particular to a method for breeding pork pigs using hybridization technology. Background technique [0002] Landrace pigs, Yorkshire pigs, and Duroc pigs are famous lean-meat pigs in the world, and they are also the main breeding breeds currently promoted in my country. In production, landrace pigs are often used as the male parent to cross with the large Yorkie pig female parent, and the offspring "Long × Big" dual hybrid sow is selected as the female parent, and the Duroc boar is used as the terminal male parent for crossing, and the "Duroc" is obtained. × long × large” three-way hybrid offspring are used as commercial meat pigs, usually called “outer three-way”. "Wai Sanyuan" has the advantages of good growth performance, high feed conversion efficiency, and high lean meat, and has become the main hybrid combination used in large-scale pig raising in my country. However, "Wai Sanyuan" pigs ...

AI Technical Summary

Problems solved by technology

Luchuan pig is an excellent breed in the eight major regions of China. Its main advantages are early maturity and easy fattening, thin skin and tender meat, good meat quality, resistance to rough feeding, easy feeding, high fecundity of sows, average litter of more than 12 piglets, and good maternity. The heredity of pigs is stable, but it also has its disadvantages, mainly short body, sunken back and waist, large abdomen, plump buttocks, slow growth rate, and low breeding remuneration
