To maintain the quality and enhance the purity of special wild boars, the following measures can be implemented:
1. Introduce 50% wild boar gilts or young sows, and 75% wild boar gilts or young boars into the breeding program. By breeding them after their second estrus cycle, the offspring can achieve up to 62.5% wild boar ancestry. This method helps in gradually increasing the genetic purity of the population.
2. Breeding pure wild boars with hybrid female wild boars can result in offspring that have 75% wild boar ancestry. However, it's essential to start with small wild boars for domestication. Typically, wild boars weighing between 5 to 25 kilograms are chosen for rearing. Larger individuals may be more difficult to handle, less adaptable, and harder to breed due to their strong wild instincts.
3. Breeding pure wild boar males with 62.5% wild boar sows can produce offspring with 81.2% wild boar ancestry. This step further enhances the genetic integrity of the special wild boar lineage.
4. Finally, breeding pure wild boar sows with 75% wild boar sows can result in offspring with 87.5% wild boar ancestry. This is the most advanced stage in the process of refining the genetic line.
By following these four methods, the offspring of the descendants can be purified and regenerated effectively. This approach significantly improves the quality and genetic purity of the special wild boar population, ensuring long-term sustainability and preventing degradation over time.
