Method for breeding new pig variety by hybridizing wild boar with domestic pig

Abstract

Disclosed is a method for breeding a new pig variety by hybridizing a wild boar with a domestic pig. The method comprises the steps that the first filial generation of wild pigs is obtained by the hybridization and improvement of purebred wild boars and small-ear sows from southern Yunnan, then, sows from the first filial generation of wild pigs and boars from Duroc pigs are hybridized, and the new pig variety is obtained. Pigs of the new variety integrate the advantages of purebred wild boars and domestic pigs, and are strong in disease resistance, high in farrowing rate, good in pork quality, strong in flavor, and high in market value.

Description

technical field [0001] The invention belongs to the technical field of pig breeding methods. Background technique [0002] Wild boar is also called wild boar, and there are different varieties of wild boar in different countries and regions. Purebred wild boars generally have thick skin, heavy fishy smell, thick meat, less meat, and low litter rate, so they have a bad taste and are not suitable for raising as commercial pigs. However, purebred wild boars have strong environmental adaptability and disease resistance. The disease resistance is obviously better than that of the raised commercial pigs. In addition, its nutritional value is high, its fat content is low, its fragrance is strong, and it has certain medicinal value, so its market value is relatively high. However, the limited number of purebred wild boars, coupled with the increasing protection of wild animals, leads to the fact that the number of purebred wild boars cannot meet the needs of the market, and some sh...

Problems solved by technology

However, existing domestic pigs generally have shortcomings such as excessive fat, insufficient fragrance, and weak disease resistance, which cannot meet the requirements of people's increasing living standards.
