Embodiment 1

[0018] The method for hybridizing wild boar and domestic pig to breed special wild boar, its specific steps are:

[0019] A. The purebred South China wild boar was used as the male parent and the purebred Xinjiang wild boar was used as the female parent to obtain the F1 hybrid wild boar;

[0020] B. Crossbreeding with the F1 generation hybrid wild boar as the male parent and the purebred Meishan pig as the female parent to obtain the F2 generation hybrid pig;

[0021] C. using the purebred South China wild boar as the male parent and the F2 generation hybrid pig as the female parent to perform crossbreeding to obtain the F3 generation hybrid pig;

[0022] D. use F3 generation hybrid sows to carry out cross-crossing with F3 generation hybrid boars to obtain cross-cross offspring;

[0023] E. Select the offspring of the cross for another 3-4 generations.

[0024] Both hybridization and cross-crossing are carried out by artificial insemination, and the ratio of male to female d...

Abstract

The invention belongs to the technical field of cross breeding, and particularly relates to a method for breeding special wild boars by crossing wild boars with domestic pigs. The method comprises the specific steps that 1, crossing is conducted by taking pure south China wild boars as male parents and taking pure Xinjiang wild boars as female parents to obtain F1-generation crossed wild boars; 2, crossing is conducted by taking the F1-generation crossed wild boars as male parents and taking pure Meishan pigs as female parents to obtain F2-generation crossed pigs; 3, crossing is conducted by taking the pure south China wild boars as male parents and taking the F2-generation crossed pigs as female parents to obtain F3-generation crossed pigs; 4, athwart crossing is conducted on the F3-generation crossed female pigs and the F3-generation crossed male pigs to obtain an athwart crossing generation; 5, the athwart crossing generation is subjected to 3-4 generations of breeding. The special wild boars bred through the method are good in reproductive performance and high in piglet survival rate.

Description

technical field [0001] The invention belongs to the technical field of hybrid breeding, in particular to a method for cultivating special wild boar by crossbreeding wild boar and domestic pig. Background technique [0002] Wild boar, also known as wild boar, is an animal of the genus Pig. 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 and 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. Wild boar has the advantages of high lean meat rate and strong game flavor. Its meat has strong aroma, rich nutrition, low fat content, and the fat in the hind legs is only 50% of that of domestic pigs. [0003] The meat of the hybrid offspring of wild boar and domestic pig (special wild boar) is more delicious, with unique flavor and ...
