In a revolving door world, sport horses don’t stay static—every few circuit cycles, new athletes capture the equestrian zeitgeist with flashy, high-profile looks, style, and brains and athleticism to boot. These trends don’t just manifest by chance, though. Breeders shape the scenes, closely monitoring industry standards, popular demands, and designing new benchmarks for the sport starting from preconception to getting progeny on the ground.
Two powerhouses of production, Rachel Kane, DVM, and Alex Jayne, sit in high ranks of the 2025 United States Equestrian Federation (USEF) Hunter and Jumper Breeder standings, respectively. Together, they have a combined experience of over half a century in selecting and breeding top-quality sporthorses, well-positioning them to answer which horse qualities they breed for that are timeless, and which have evolved to elevate the next generation.
Jayne is a fifth-generation horseman and heads Our Day Farm, a highly successful hunter/jumper breeding, training, and sales business, which includes his three children, Maggie, Charlie, and Hailey, with lauded professional careers of their own. He established his breeding base for producing globally competitive jumping talent from their stock of horses.
“I was extremely lucky that I had some top international horses as my foundation mares,” says Jayne. “So, I started with all the things you look for: good brains, athleticism, great canters, nice jumping technique, and straight legs.”
Now, most of Jayne’s equine offspring are related to the horses Charlie campaigned at the highest level of show jumping; not just horses with quality bloodlines, but proven champions. “We look for longevity in the mares, because that passes on to their foals,” says Jayne.
Kane, a practicing equine veterinarian who owns Entropy Farm, a boarding, breeding, and sales barn, has a similar approach. “As an established veterinarian, I was able to get some connections through which I was able to get some really good mares, and that’s really the crux of it all,” she says. “You can really get stud samples easily these days, if you’re willing to pay, but getting the mare power and the dam lines with strong genetics is the hard part.”
Her baseline for top hunters is a good mind, a good jump, and a good canter. “Everybody wants to be the hack winner, which is nice if you get that, but that’s only one class, and in all their other classes, they have to canter, and the canter is more related to their jump than the trot,” she says.
She views longevity as being hand in hand with mental fortitude. “Good-minded horses aren’t just going to be more sellable but tend to stay sound longer, because they want to do their job and don’t have to do as much physically to understand their job well,” says Kane.
In the elite jumper world, Jayne notes that while top stallions were heavy 10-15 years, there’s been a shift to a much lighter type.
Over the years, international horse breeders have sought physically and mentally quicker, more careful, and agile sporthorses to meet the technical, highly dialed challenges that current course designers and training programs present.
Meanwhile the establishment of and growing participation in accessible lower hunter divisions at horse shows has the hunter culture gravitating away from the Thoroughbred types toward purebred warmbloods. “You want a horse that can do it naturally and not have to be lunged for hours in order to be a metronome,” says Kane, who supports the growth of inclusive levels but adds, “Somewhere in there, it’s our job to figure out how to still make it right for the horse.”
A breeder’s responsibility doesn’t end when a foal’s hooves hit the ground—they contribute to a world where their horses can fit and thrive, one open door at a time.
