Basic Information

Pharmacological Overview

Altrenogest mimics natural progesterone by suppressing gonadotropin release from the pituitary gland, temporarily inhibiting estrus and ovulation. After withdrawal, animals return to estrus predictably, allowing precise management of breeding schedules and reproductive outcomes.

Applications in Veterinary Reproduction

Estrous Synchronization

Altrenogest is used to synchronize estrus in mares and sows. Administered over a defined period, it suppresses heat, allowing animals to return to estrus simultaneously after withdrawal. This improves artificial insemination efficiency and facilitates coordinated parturition planning.

Behavioral Management in Performance Horses

In performance mares, estrus-related behavior can disrupt training and competition. Altrenogest suppresses estrus, maintains stable behavior and consistent performance, making it valuable in racing, dressage, and show-jumping horses.

Support of Early Pregnancy

Altrenogest supplements progesterone activity in mares with reproductive difficulties, stabilizing the uterine environment, reducing early embryonic loss, and increasing the likelihood of maintaining a successful pregnancy.

Breeding Management in Swine Production

In swine, altrenogest synchronizes estrus in sows and gilts, enabling predictable farrowing, uniform piglet groups, and efficient labor and facility management. This synchronization enhances productivity and operational efficiency.

Key Benefits

Safety and Proper Use

Altrenogest should be used under veterinary supervision to ensure correct dosing and administration. Proper use maximizes reproductive outcomes while maintaining animal safety. When administered appropriately, altrenogest is a safe and reliable hormone for reproductive control.

Summary

Synthetic progestational hormone Altrenogest is a key component in modern veterinary reproductive management. It regulates estrous cycles, supports pregnancy, enhances performance, and improves breeding efficiency in equine and swine systems. With professional oversight, altrenogest delivers consistent, safe, and effective reproductive outcomes.
