Abstract

The invention provides a breeding method of special wild pigs. The breeding method of the special wild pigs includes: selecting a purebred Changbai mountain wild boar as a male parent, selecting a lean type sow as a female parent, hybridizing the purebred Changbai mountain wild boar and the lean type sow, and then mating a boar which has 62.5% of special wild pig blood and a sow which has 62.5% of the special wild pig blood in crossing fixed mode so as to obtain the special wild pigs which have 62.5% of the special wild pig blood and high in quality. By using the breeding method of the special wild pigs, the obtained special wild pigs have the advantages of being high in growth speed, good in adaptability, strong in disease resistance and rich in nutriment.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a method for breeding special boars. Background technique [0002] Changbai Mountain wild boar, also known as wild boar, also known as wild boar (Sus scrofa), has a very wide distribution range. China's wild boars are mainly distributed in the three northeastern provinces, Yunnan-Guizhou, Fujian, and Guangdong. On the one hand, the number of purebred wild boars has been drastically reduced due to factors such as human hunting and the sharp reduction of living environment space, and has been listed as an endangered species by many countries. However, purebred wild boars have slow growth, light weight, limited number of wild boars, thick meat, thick skin, poor meat taste, etc. It is not suitable for simple domestication and promotion, and wild boars are in estrus seasonally, with few litters, and are not easy to raise. . And people seek wild game and improve taste and the re...
