The Effect of Ovarian Cyst Aspiration on the Dairy Cow Pregnancy Rate
Keywords:

In dairy cows' reproduction, ovarian cysts are one of the most significant contributors to infertility, leading to considerable economic losses. The approach to treating ovarian cysts can vary depending on the type of cyst. For follicular cysts, the recommended treatment is the administration of GnRH. In contrast, luteal cysts are typically treated with PGF2α. This study aims to evaluate the effects of ovarian cyst aspiration on reproduction of dairy cows. For this study, twenty repeat-breeding dairy cows diagnosed with follicular cysts were divided into two groups, each consisting of 10 cows: the OCE group (n = 10) and the OCP group (n = 10). In the OCP group, the ovarian cyst aspiration was performed on the day of cyst diagnosis, while the cows in the OCE group did not receive any treatment for 21 days. Compared to the OCE group, in which 20% registered a spontaneous recovery, in the OCP group, 60% of the cows recovered from the first aspiration, 40% required a second ovarian cyst aspiration. Finally, the pregnancy rate was 40% in the OCP group and 10% in the OCE group. This preliminary result provides the premises for future studies regarding ovarian cysts ultrasound-guided transvaginal aspiration.
