Embodiment Construction

[0014] The present invention includes the following steps: (1) using Heilongjiang Dajiazi black pig as the female parent and Daxinganling wild boar as the male parent to carry out the first artificial hybridization to produce a second-generation sow; (2) the second-generation sow and the American Duroc The boars were artificially crossed a second time to produce three generations of pigs. The third-generation pigs can feed on corn stalks, bean stalks, peanut seedlings, rice straw, grass, and leaves.

[0015] The first artificial hybridization is to put the Heilongjiang big black pig in the wild and mate with the Daxinganling mountain wild boar under the condition of artificial remote guard.

[0016] The second artificial hybridization is artificial semen collection for breeding.

[0017] On the seventh day after the birth of the second-generation sows and third-generation pigs, the paste made of cornmeal, soybean meal, and clear water was manually applied to the mouth...

Abstract

The invention particularly relates a ternary-hybridization pig breeding method, belonging to the technical field of vertebrate breeding. Due to the ternary-hybridization breeding method, the ternary-hybridization pig resists coldness, has strong disease resistance and strong fecundity and is high in lean factor and quick in growth speed. The ternary-hybridization pig breeding method comprises the following steps that: (1) by taking a black pig in Heilongjiang province as a female parent, and taking a wild boar in Great Khingan mountain range as a male parent, primary artificial hybridization is conducted to generate the second generation of sow; and (2) the second generation of sow and an American Duroc boar are subjected the secondary artificial hybridization to generate the third-generation pig.
