Ternary-hybridization pig breeding method

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.

[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

(2) slow growth

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
