OvaMed (Altrenogest) Solution 0.22% 1 Liter

Altrenogest Oral Solution for Estrus Suppression in Mares

Product Description

OvaMed® (altrenogest) is a prescription oral solution formulated for horses to help control the estrus cycle in mares. Each ml contains 2.2 mg of the synthetic progestin altrenogest, which produces a progestational effect that suppresses estrus. This controlled suppression helps veterinarians and breeders manage reproductive cycles, regulate breeding schedules, and support predictable estrus after treatment withdrawal. It is commonly used under veterinary supervision to assist with reproductive management, including mares experiencing prolonged estrus or those requiring scheduled breeding.

Benefits

• Breeding Schedule Control: Supports planned breeding programs. It enables veterinarians and breeders to schedule estrus more accurately.
• Manages Prolonged Estrus: Helps manage mares that show prolonged estrus behavior during seasonal reproductive changes.
• Veterinary Controlled Therapy: Prescription formulation designed for safe reproductive management under veterinary supervision.
