Bringing Science to Your Feed Bin

Equine nutrition can be confusing, yet owners have voted health and nutrition the topics they most want to learn about! With that goal in mind and the belief that better information makes for healthier horses, educating horse owners is a key responsibility for equine veterinarians, and the key role of Jenquine.

  • "We’ve been feeding Jenquine EzyMag+ for about 4 years now to both competition horses as well as our mares and foals. Our competition horses have thrived on EzyMag for recovery and for keeping their minds calm. Our pregnant mares have stayed happy, healthy and mobile later in the pregnancy stage and their foals grow-up looking shiny, strong and sound. Since feeding them EzyMag after weaning, you really notice a difference in their demeanour about others coming and going, they have more confidence in themselves."
