Problems solved by technology

[0002]Heilongjiang big shelf black pig, large in body and large in litter, 12 to 16 pigs per litter, but its lean meat percentage is low
[0003]The Daxinganling wild boar is a breed that has been naturally selected and cultivated for thousands of years in the special ecological environment of the Daxinganling forest in the back of Heilongjiang. The appearance characteristics are " Tall, big, and thick", the intrinsic characteristics are "fragrant (meat flavor), pure (gene pure), luster (no pollution)", and the lean meat rate is high, with a lean meat rate of more than 85%. It is a high-quality processed meat. It is a high-quality raw material for products, and has medicinal and health value, but it has the following disadvantages: (1) Low fecundity
The disadvantage is that the fecundity is not too high, the motherhood is poor, the carcass meat yield is slightly low, and the fat content between muscles is relatively high

Embodiment Construction

[0014] The present invention includes the following steps: (1) using Heilongjiang Dajiazi black pig as the female parent and Daxinganling mountain 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 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 mash mixed with cornmeal, soybean meal, and clear water was manually applied to th...

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.
