Embodiment 1

[0021] A breeding method for an excellent pig breed, comprising the steps in turn:

[0022] (1) Xiangza first generation: Tibetan pigs are used as the male parent and Bama pigs are used as the female parent, and the first generation of Xiangza is obtained after crossbreeding;

[0023] (2) The first generation wild hybrid: the wild boar is used as the male parent, and the Xiangxi Tuhei pig is used as the female parent, and the first wild hybrid is obtained after crossbreeding;

[0024] (3) Then, the first generation of pure black hair Xiangza was used as the male parent, and the first generation of pure black hair wild hybrid was used as the female parent, and the second generation of Zayou was obtained by crossing.

Embodiment 2

[0026] A breeding method for an excellent pig breed, comprising the steps in turn:

[0027] (1) Xiangza first generation: Tibetan pigs are used as the male parent and Bama pigs are used as the female parent, and the first generation of Xiangza is obtained after crossbreeding;

[0028] (2) The first generation wild hybrid: the wild boar is used as the male parent, and the Xiangxi Tuhei pig is used as the female parent, and the first wild hybrid is obtained after crossbreeding;

[0029] (3) Then, the first generation of pure black hair Xiangza was used as the female parent, and the first generation of pure black hair wild hybrid was used as the male parent, and the second generation of Zayou was obtained by crossing.

[0030] The characteristics of the second-generation meat-eating pigs obtained in the above examples 1-2 after adulthood are as follows.

[0031] Example 1: The body is relatively large, and its body size is larger than that of Tibetan pigs, Bama pigs, wild boars ...

Abstract

The invention relates to a method for cultivating excellent pig breeds. The method sequentially includes steps that (1), for the Tibetan-Bama minipig first generation, a male Tibetan pig is taken as amale parent, a female Bama minipig is taken as a female parent, the Tibetan-Bama minipig first generation is obtained through hybridization; (2), for the wild boar-Xiangxi native black pig first generation, a male wild boar is taken as a male parent, a female Xiangxi native black pig is taken as a female parent, the wild boar-Xiangxi native black pig first generation is obtained through hybridization; and (3), the heterozygous excellent second generation is obtained through hybridization of the Tibetan-Bama minipig first generation and the wild boar-Xiangxi native black pig first generation.The method is advantaged in that a pig obtained by the method has a large skeletal body and the high meat yield.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a method for cultivating fine pig breeds. Background technique [0002] Wild boar (scientific name Sus scrofa) is also called wild boar, belonging to the pig family. Wild boar is divided into European wild boar and Asian wild boar. There are 27 subspecies in the world. There are some differences between subspecies and subspecies karyotype. The number of chromosomes (2n) is between 36-38, such as Western European wild boar 2n=36 or 37, Japanese wild boar 2n=38, but there is no reproductive barrier between each other. They can give birth to offspring. They are widely distributed in the world, but due to factors such as human hunting and the sharp reduction of living environment space, the number has decreased sharply, and they have been listed as endangered species by many countries. Wild boars are delicious, but purebred wild boars grow slowly and weigh le...
