Regumate® Equine 2.2 mg/ml Oral solution for horses
Regumate Equine is a hormonal treatment, used to suppress and prevent the signs of oestrus in mares, which may be particularly useful early in the breeding season. It is also used strategically as part of a breeding program to control the cycle of breeding mares, allowing synchronisation of oestrus and mating, which means greater efficiency of time spent at stud.
