Our founder
Our founder, Igor Canisso, a naturalized American, has spent most of his career in the U.S., studying and working at leading universities and breeding centers. His childhood on a cattle and horse ranch in Brazil sparked his passion for veterinary medicine and animal breeding.
After earning his veterinary degree, he completed advanced postgraduate training in equine reproduction, including a master’s in stallion semen cryopreservation and behavior, a fellowship at Aberystwyth University in the UK, a residency at Cornell University in New York, and a PhD from the University of Kentucky. He is a board-certified specialist in Equine Reproduction by both the American College of Theriogenologists (ACT) and the European College of Animal Reproduction (ECAR).
Dr. Canisso is a tenured Associate Professor at the University of Illinois Urbana-Champaign College of Veterinary Medicine, where he provides reproductive services at the Veterinary Teaching Hospital and at privately owned farms and centers. He has mentored dozens of graduate students, veterinary interns, and residents. He is a world-renowned speaker at scientific and veterinary continuing education programs for equine veterinarians, focusing on practical, evidence-based reproductive management, troubleshooting, and advanced assisted reproductive techniques.
Dr Canisso has been one of the world-leading clinical scientists of his era, publishing nearly 200 manuscripts and dozens of book chapters. In 2025, he was honored as “Theriogenologist of the Year,” the highest national award presented by the American College of Theriogenologists to a board-certified veterinary specialist in animal reproduction.
Dr Canisso provides consulting and advisory services on high-end stallions and mares to breeders, farm managers, and veterinarians worldwide. He makes his top-tier expertise in equine reproduction, including subfertility in mares and stallions, and equine perinatology, available to the global horse industry. He founded the ACN Ranch LLC to provide stallion management services, continued education, and consulting services to the horse industry.
