Estradiol Benzoate Injection for Animal

As artificial insemination becomes more and more commonplace in the beef cattle industry, producers are continuously looking for estrus or ovulation control systems that will provide them with more consistent results. Injection of progesterone-like compounds, or progestagens, has long been the standard for preventing estrus. However, cows injected with Estradiol Benzoate have nearly double the pregnancy rates than cows not treated with the medication.

Generic Name: Estradiol Benzoate Injection

[Main Ingredients]Estradiol benzoate

[Description]This product is a colorless or light yellow clear oily liquid

[Functions]Estradiol promotes normal growth and development of female organs and secondary sexual characteristics. It can increase the secretion of cervical mucosal cells, thicken vaginal mucosa, promote endometrial hyperplasia and increase uterine smooth muscle tension. Estradiol also affects the skeletal system: increasing bone calcium deposition, accelerating skeletal closure and bone formation, and moderately promoting protein synthesis, as well as increasing water and sodium retention. In addition, estradiol also negatively regulates the release of gonadotropins from the anterior pituitary gland, thereby inhibiting lactation, ovulation, and secretion of male hormones.

[Indications] To treat retained fetal membranes, metritis and pyometra, and can help eliminate uterine inflammatory substances, stillbirth, and oxytocin production. Small doses are used for animal aphrodisiasis in estrus, excessive estrus in female dogs, and breast swelling and pain in pseudopregnant dogs.
