Here's why:
* Bloodlines are not static: Bloodlines are dynamic and constantly evolving. Every foal inherits a unique combination of genes from its parents, resulting in new variations and a changing bloodline.
* No permanent "contamination": There is no permanent "contamination" from breeding to a different bloodline. The genes from the opposing bloodline are simply incorporated into the mare's offspring. Subsequent generations will continue to inherit a mix of genes from their ancestors, including both the original bloodline and the "opposing" bloodline.
* Diversity is beneficial: Introducing new bloodlines can actually be beneficial to a breeding program. It can bring in new traits, improve genetic diversity, and potentially reduce the risk of genetic disorders that might be prevalent within a closed bloodline.
Instead of "contamination," think of it as "enrichment." By bringing in new bloodlines, you are expanding the genetic pool and potentially creating horses with unique and desirable characteristics.
Important Considerations:
* Careful planning: When introducing a new bloodline, it's important to carefully consider the traits you're looking for and the potential risks.
* Know your lines: Understanding the pedigrees of both the mare and the stallion is crucial to make informed breeding decisions.
* Experienced guidance: Consult with a knowledgeable veterinarian or breeder for advice on bloodline management.
Remember, breeding is a complex process, and success involves understanding genetics, making informed choices, and embracing the dynamic nature of bloodlines.
