Progesterone

Progesterone

Progesterone is a natural steroid hormone essential for veterinary reproductive management and fertility control in livestock and companion animals. It plays a critical role in the regulation of the estrous cycle, the preparation of the uterus for implantation, and the maintenance of pregnancy. In veterinary practice, Progesterone is extensively used for estrus synchronization (bringing animals into heat at the same time), enabling Fixed-Time Artificial Insemination (FTAI) which significantly improves breeding efficiency. It is also the primary treatment for conditions such as habitual abortion, ovarian cysts, and silent heat. Available in various formulations—including injectable oil solutions, intravaginal progesterone releasing devices (like CIDR), and implants—it is a cornerstone tool for optimizing reproductive performance in dairy and beef herds.

FAQ（Progesterone）

1. What is Progesterone used for?
It is primarily used for regulating the estrous cycle (heat synchronization), preventing habitual abortion (maintaining pregnancy), and treating reproductive disorders like cystic ovaries in cattle and mares.

2. How is Progesterone administered?
It is commonly administered via intramuscular injection (oil-based solution) or through intravaginal devices (inserts) which release the hormone slowly over several days to block estrus until removal.

3. Which animals can use Progesterone?
It is most extensively used for cattle (dairy and beef cows), horses (mares), sheep, and goats; it is also used in dogs and cats for specific reproductive therapies.

4. Is Progesterone safe for livestock?
Yes, it is safe when used according to veterinary reproductive protocols. As it is a hormone, it should be handled carefully by operators, and specific withdrawal periods may apply depending on local regulations.

5. Can Progesterone be used for herd management?
Yes, it is the key component of estrus synchronization programs, allowing farmers to schedule breeding times precisely, improve conception rates, and shorten the calving interval in the herd.
