Today, as we watch a class full of horses compete in the show pen, it’s no longer a surprise to see full siblings, often the same age, competing against each other. Because of modern scientific advances, we’ve become totally accustomed to raising horses very differently than our ancestors, who used live cover. In fact, acronyms like “AI” or phrases like “pull an embryo” are frequently used within casual conversations since we know our horse cohorts will understand that, nowadays, we can produce horses using stallions from afar, or without a mare ever carrying her own foal.
