Embodiment Construction

[0022] The method for breeding and raising hybrid pigs comprises the steps of:

[0023] 1) Selection of parents: choose a variety or strain with a large number of local areas and strong adaptability as the female parent; choose a purebred variety or strain with fast growth and good carcass quality as the male parent, such as: the male parent can choose Daxia Yorkie, Large White or Duroc.

[0024] 2) Hybridization combination: binary crossing and binary recurrent crossing are used. The binary crossing is to use two breeds or strains of male and female pigs for crossing to obtain the first generation of hybridization. Select excellent sows in the first generation, and mate with purebred boars of the female breed and another breed in turn;

Before the mid-1990s, my country had always been an exporter of the pork industry. Since 2000, we have become a pork importing country. In 2000, my country's import volume exceeded 5 million tons for the first time, and reached 1,300 tons in 2007, and more than 80% of them were feed fast-fed pork imported from Brazil and Argentina. Although the impact of fast-feeding pork on human health is still inconclusive, But there are many controversies. Moreover, some countries in the world have explicitly banned the import of fast-feeding pork, and our people clearly feel that fast-feeding pork is far inferior to pork produced by traditional f...
