A study on the relationship between some serum biochemical parameters and the incidence of ovarian cysts in Dairy farms in Arak, Iran.

Ovarian cyst is one of the most important diseases that leads to reproductive disorders and many economic losses in dairy cows. The aim of the present study was to evaluate the blood serum biochemical parameters including glucose, phosphorus, total protein, blood urea nitrogen and triglyceride, and also some clinical features in cows with ovarian cysts and compare them with healthy cows. In this study 80 dairy cows were divided to 2 groups of cows with ovarian cysts and healthy cows that contain 40 cows, then blood samples and their clinical information were collected. The results of the present study showed that the most type of the ovarian cysts are luteal, and anestrus is the most common clinical symptom observed in cows with ovarian cysts. Furthermore, evaluation of serum biochemical parameters showed that there were no significant differences in BUN, phosphorus and total serum protein levels between cystic and healthy cows, while glucose and triglycerides levels were significantly different. It can be concluded that low glucose and high triglyceride levels play an important role in the development of ovarian cysts in the study area.
