Abstract: 

Introduction: Human Chorionic Gonadotropin (hCG) has a variety of applications in the treatment of human and animal reproduction disorders. This study aimed at investigating its influence on cattle with repeated estrus or ovarian cysts.
Methods: Intramuscular or intravenous doses between 1500-4500 IU of two injectable forms, Pregnan 1500
Ò (Daroupakhsh Pharmaceutical Company, Iran) and ChorulonÒ (Intervet, the Netherlands) were tested on 64 cattle with a background of reproduction failure or the presence of ovarian cysts in Urmia region.
Results: A 1500 IU or higher i.m. dose of Pregnan
Ò was able to increase the rate of pregnancy in all treated animals. In case of ovarian cysts, 1500 IU failed in the treatment, however, 3000 IU and 4500 IU treated 60% and 80% of the animals, respectivelyÒ Comparison of the effects of this drug with ChorulonÒ showed a full similarity in affecting the conception rate and a partial similarity in treating the ovarian cysts.
Conclusion: In the cow, a single i.m. or s.c. injection of Pregnan
Ò is recommended for treating repeated estrus (1500 IU) and ovarian cysts (3000 IU; or 4500 IU just to make sure of its effectiveness). Lack of acute reactions following injection, its safety in respect to drug residue problems, and the similarity of its effectiveness with that of ChorulonÒ makes PregnanÒ a suitable medicine in the treatment of reproduction failure and ovarian cysts in cattle.
