First, the introduction of 50% of the hybrids of wild boar pedigrees, male and female breeding pigs, after mating (up to 45 kg to 50 kg body weight) for breeding, after 114 days of pregnancy, the piglets born to the pigs are still 50% of the wild boar, which is called " Expanding." According to this breeding, despite the avoidance of inbreeding, but because of its ancestors home pig is used as a female parent (such as the United States Department, the Department of Duroc, etc.), from the biological point of view, there will be a return to the ancestral phenomenon With a long expansion time, the wild boar gene (blood line) is inevitably reduced. For this reason, the following measures can be taken to avoid degradation and increase the purity of special wild boars.
1. Introduce female pigs or young sows with 50% wild boar pedigrees, or dolls or young boars with 75% wild boar ancestry. After raising, breed breeding in the second estrus period. 62.5%.
2. Breed purebred wild boars and one-generation hybrid female wild boars to breed special boars that account for 75% of wild boar pedigrees. Breeding purebred wild boars should be started from a small age. Normal boars weighing 5 kg to 25 kg are generally selected for domestication and rearing. Otherwise, the body weight is too large, the wildness is difficult to tame, the plasticity is poor, the breeder is not easy to access, and it is not convenient for the breeding operation.
3. Purebred boars and wild boars with wild boar pedigrees account for 62.5% of the species. Breeding breeds 81.2% of wild boars.
4. Breed pure boar wild boar and special wild boar which account for 75% of wild boar bred, breed special wild boar which account for 87.5% of boar ancestry.
Through the above four methods to purify and regenerate the offspring of the offspring of the offspring and then reproduce and multiply the breeding population, which can greatly improve the quality and purity of the special wild boar, prevent degradation, increase market share, and provide new food sources for humans.
