Abstract

Abstract. Farmers experience significant economic damage due to prolonged infertility of cows with an ovarian cyst. Therefore, doctors of veterinary medicine are constantly improving methods of treating sick animals. However, the development of therapeutic interventions should take into account the effectiveness and cost of selected hormonal drugs. In this regard, the purpose of our work was to study the effectiveness of hormonal schemes in restoring reproductive function in cows with follicular ovarian cysts. The research was conducted in the ALLC named by Vatutin, Zvenigorodsky district, Cherkasy region, on black-and-white and red-and-white Ukrainian breed cows.
In the control group, exfoliation of the cyst was used to treat animals. During the treatment of the cows of the first experimental group, three injections of 5 ml of the surfactant and two injections of 2 ml of Estrophan were used. The therapeutic scheme in the second experimental group of animals was consisted of two injections of 2.5 ml of Fertagil and 2 ml of Estrophan. In the third experimental group of cows, two injections of 2 ml of Ovarelin and one injection of 5 ml of ezaprost were used.
After exfoliating the ovarian follicular cyst, only 30.0 % of the cows become pregnant. The most effective hormonal regimen as to restoration of reproductive function in cows with a follicular cyst of the ovarian glands is the use of Ovarelin and Enaprost. Such therapeutic regimen contribute to a 29.2% increase in the number of pregnant animals, a reduction of 16.0 days (p < 0.05) of the duration of infertility and and a decrease by 1.0 of the insemination index. It is promising to study endocrine changes when using various methods of treating cows with a follicular ovarian cyst.
