Commercial pig breeding method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a breeding method for commercial pigs. Background technique [0002] Pork is the most important source of animal protein for the general public. According to statistics, more than 70% of the animal protein consumed in my country is pork and its products. Since the 1970s, people's nutritional concepts and dietary structure have changed, coupled with the improvement of living standards, people's demand for pork has changed from quantity to quality, and the requirements for meat quality have increased significantly. Pig breeds from all over the world Breeding programs are also turned to improve the meat performance of commercial pigs. [0003] The current mainstream pig breeds are: [0004] Large York pig: tall and big, with all white coat, long head and neck, wide and slightly concave face, forward erect ears; long body, flat back and waist [0005] Straight or slight...

Problems solved by technology

[0008] At present, although many domestic pig breeds have been optimized for breeding, due to the influence of the environment, climate, feed, etc., although the taste of the meat has improved, the long-term uninterrupted breeding has also formed the inbreeding of domestic pigs, which directly affects the growth of pigs. and pig quality
