This paper presents results of investigations of gonadoreline application (14-16, 17-20 and 21-25 days post partum) influence, followed by prostaglanin F2 α ten days later, on the reproductive parameters of dairy cows with difficult calving and endometritis. The study was carried out on a total of 92 Holstein-Friesian cows. Fifty of them treated with hormones, while 42 animals served as controls, receiving placebo injections. Analysis of the results in cows with postpartal endometrits revealed that mean anoestrus period, open days period and intervals between calving were significantly lower in cows that underwent hormonal treatment, when compared to the controls. The period from gonadoreline application, followed by prostaglandin injection, to conception was shorter by 44, 28 and 14 days respectively when compared to the control groups. The total conception rate from the first three artificial inseminations was higher in the experimental groups in comparison to the controls.
