Method for cross-breeding special wild boar through domestic boar and wild boar

Abstract

The invention relates to the technical field of raise livestock breeding and cultivating, and in particular relates to a method for cross-breeding a special wild boar through a domestic boar and a wild boar. The method comprises the steps of patriarchal breeding, maternal breeding, patriarchal and maternal cross-breeding, and continuous progeny selection, wherein patriarchal breeding and maternal breeding involve first cross and first backcross; patriarchal secondary boar contains 75% of consanguinity of wild boar, and 25% of consanguinity of duroc and has the characteristics of being fast to grow and high in lean meat percentage; maternal secondary boar contains 75% of consanguinity of wild boar, and 25% of consanguinity of Jiangkou radish boar and has the characteristics of growing well on the roughest of forage, and being peaceful, and high in maternity; patriarchal secondary boar and maternal secondary boar which are gained after backcrossing are crossed to obtain first-generation special boar, and then the three-generation selection is performed for the first-generation special bar to obtain a special boar core group that contains 75% of consanguinity of wild boar, 1.25% of consanguinity of duroc, and 12.5% of consanguinity of Jiangkou radish boar. According to the method, the size and appearance of the special wild boar are close to that of the wild boar, and the special wild bar is peaceful and grows well on the roughest of forage; white doar and flower boar descendants nearly do not appear; the special wild boar grows fast, the meat is delicious, and the lean meat percentage reaches 66%; linoleic acid in meat accounts for 8% to the maximum based on the total fatty acid, which is 2 to 3 times that of the common domestic boar, and thus the benefit is brought to human health.

Description

technical field [0001] The invention relates to the technical field of animal breeding and breeding, in particular to a method for breeding special wild boars by crossbreeding domestic pigs and wild boars. Background technique [0002] As we all know, pork is the main meat food in China. Scientific research has shown that ordinary pork has high fat and cholesterol content, and long-term consumption of large amounts has adverse effects on people's health. Therefore, with the improvement of people's living standards, ordinary pork can no longer meet the needs of consumers. Products are in increasing demand. [0003] The wild boar is the ancestor of the domestic pig. It is distributed in most areas of my country and has extremely rich genetic resources. The characteristics of wild boar with high lean meat rate and low cholesterol content are in line with the changing trend of people's meat consumption needs, thus stimulating people's interest in the development and utilizatio...

AI Technical Summary

Problems solved by technology

[0006] Since the special wild boar breeding industry is an emerging industry, related research is seriously lagging behind. The hybridization methods of wild boars and domestic pigs reported by different regions and different companies are very different. Even in the same company, there are random mating between wild boars and domestic pigs. The above phenomenon This makes the special wild boar products on the market lack uniform standards, and the quality is difficult to guarantee
