Used in veterinary medicine as a progestin for estrus synchronization and management of reproductive cycles in livestock, particularly in cattle. It helps control the timing of ovulation, improving breeding efficiency in dairy and beef operations. Commonly used in combination with other hormones like estradiol or prostaglandins in protocols for timed artificial insemination. Its long-acting nature allows for sustained hormonal effect from a single injection, making it practical for use in large herds. Also utilized in research settings to study reproductive physiology and hormone effects in animals.
