Use
- Regulate the estrous cycle: This drug is primarily used in animals such as pigs and horses to control their reproductive cycles. It works by suppressing the pituitary gland's secretion of gonadotropins, thereby preventing follicular development and estrus. Once the treatment is discontinued, the pituitary resumes hormone secretion, triggering estrus in treated animals within 5–8 days. This synchronization allows farms to manage breeding in batches, improving control over reproductive timing and enhancing breeding efficiency.
- Improve reproductive performance: The medication not only synchronizes estrus in sows but also contributes to improved reproductive outcomes. It has been shown to increase the number of piglets per litter, enhance their birth weights, reduce the incidence of mummified fetuses, and raise the farrowing rate. Additionally, it helps prevent premature birth and limits excessive backfat accumulation in sows after weaning.
- For animal contraception: It can also be used for contraceptive purposes in animals, such as dolphins, serving as an effective means of population control in specific cases.
Advantages
- Easy to use: Often available in oral formulations like allynogest oral solution, the medication can be given directly without the need for injections. This simplifies the treatment process, reduces labor demands, and minimizes stress responses typically caused by injections.
- Significant effectiveness: The drug delivers clear and reliable results in synchronizing estrus in sows, leading to high rates of estrus synchronization. This precision in controlling reproductive timing enhances batch breeding, streamlines management, and boosts productivity.
- High safety: Products such as tetraene estrone, manufactured using advanced technologies, are known for their purity, consistent quality, and absence of teratogenic effects. When used as directed, they have no notable negative impact on animal health or reproductive performance and leave no harmful residues in meat or other animal products, ensuring food safety.
- Good stability: Certain formulations, like crystalline allynogest, are characterized by their strong potency, consistent quality, and narrow melting point range. The active ingredients remain highly effective even after two years of storage, and product integrity is maintained for up to 60 days after opening. This stability helps prevent drug degradation during use or storage, reducing costs and supporting more efficient breeding operations.
