The reason why wild boar offspring look like domestic pigs is because the bloodlines of the breeding pigs are too poor.
Attention should be paid to the introduction of special wild boars:
Introduce female pigs or young sows with 50% wild boar blood, and male pigs or young boars with 75% wild boar blood. During the second estrus period, breeding is carried out, and the piglets produced can reach 62.5% wild boar bloodline.
Pure wild boars are bred with first-generation hybrid wild boars to produce special wild boars with 75% wild boar bloodline. However, when breeding pure wild boars, attention should be paid to starting from young wild boars. Generally, pure wild boars weighing 5 kg to 25 kg are selected for domestication and breeding. Otherwise, the weight is too large, the wildness is difficult to change, and the plasticity is poor, making it inconvenient for breeders to access it and breeding operations.
Pure-bred wild boars are bred with special wild boar sows accounting for 62.5% of the wild boar bloodline to produce special wild boars accounting for 81.2% of the wild boar bloodline.
Pure-bred wild boars are bred with special wild boar sows that account for 75% of wild boar ancestry to produce special wild boars that account for 87.5% of wild boar ancestry.
Using the above four methods to purify and rejuvenate the offspring piglets and then horizontally mate and reproduce them. Mass production of ideal special wild boar populations can greatly improve the quality and purity of special wild boars and prevent degradation.
