Altren 2.2 mg/mL Oral Solution is most commonly prescribed for suppression of estrus in mares.
Suppression of estrus allows for a predictable occurrence of estrus following drug withdrawal in mares with ovarian follicles 20 mm or greater. Suppression of estrus will facilitate:
● Attainment of regular cyclicity during the transition from winter anestrus to the physiological breeding season.
● Management of prolonged estrus conditions.
● Scheduled breeding during the physiological breeding season.
