The invention discloses a commercial
pig breeding method. The method comprises the following steps that 1, an individual or a family
system of Huainan black pigs which are healthy and obvious in varietal characteristics is selected to form a parent line, and the parent line is optimized and purified through small group locking breeding; 2, hybridization is performed by taking a sow which is healthy, obvious in varietal characteristic and excellent in performance and is selected from the optimized and purified parent line as a first female parent and taking a Yorkshire
boar as a first male parent, and a Huainan binary
hybrid pig is obtained through production; 3, hybridization is performed by taking the Huainan binary
hybrid sow as a second female parent and taking a Duroc
boar as a terminal male parent, and a target commercial pig is obtained through production. Accordingly, the Huainan black sow and the Yorkshire board are subjected to improved hybridization, then the obtained pig andthe Duroc
boar are subjected to hybridization, the advantages of the Huainan sow, the Yorkshire pig and the Duroc pig are integrated, and the commercial pig has the advantages of being good in meat quality, high in
lean meat percentage, high in feed return rate, large in number born, high in
disease resistance and high in environmental adaptability.
