Altresyn (Manufacturer may vary)

Altresyn, also known as Altrenogest, is a synthetic hormone commonly used in horses. It is primarily used to regulate and control the estrous cycle in mares. Altresyn helps suppress or synchronize heat cycles, making it useful for managing reproductive activities in breeding programs or controlling behavior in performance mares.

It is essential to consult with a veterinarian before using Altresyn or any other medication for your horse. A veterinarian can evaluate the specific needs of your horse and provide appropriate dosing instructions and guidance on its usage. They can also ensure that Altresyn is suitable for your horse's health and well-being, taking into account any pre-existing conditions or medications your horse may be taking.

Remember, using any medication without proper veterinary guidance can pose risks to your horse's health. Therefore, it is always advisable to seek professional veterinary advice before administering any medications to your horse.

1. Suppression of estrus: Altresyn can be used to suppress or inhibit the heat cycles in mares. This can be particularly beneficial in cases where the owner or breeder wants to control the timing of breeding or prevent unwanted behavior associated with estrus.
2. Synchronization of estrus: Altresyn can be used to synchronize the estrous cycles of multiple mares, making it easier to plan and manage breeding programs. By controlling the timing of estrus, breeders can optimize the chances of successful fertilization and improve efficiency in their breeding operations.
3. Behavioral control: Mares in heat can exhibit behavioral changes that may affect their training or performance. Altresyn can help control these behavioral changes, allowing the horse to focus on training or competition without the distraction of heat-related behaviors.
4. Improved reproductive management: Altresyn enables breeders to have better control over the reproductive management of their mares. It provides flexibility in planning and scheduling breeding activities, optimizing the chances of successful conception and pregnancy.
5. Reduced risk of accidental pregnancies: By effectively suppressing or synchronizing the estrous cycle, Altresyn helps reduce the risk of accidental pregnancies in mares. This can be especially useful for owners who do not wish to breed their mares or need to temporarily prevent pregnancy.

It's important to note that while Altresyn offers these benefits, it should only be used under the guidance and supervision of a veterinarian who can determine the appropriate dosage and duration of treatment for each individual horse.
