Housing conditions, parameters of fertility and occurrence of different types of infertility in a group of 1641 breeding cattle are described. Biochemical parameters of blood serum from 150 infertile cows suffering from endometritis and treatment results regarding a possible relation between nutrition and infertility of the animals are reported, as well as results of treatment of endometritis using several methods in 147 infertile cows. The results show that hormonal disorders are the most common reasons of infertility and low concentrations of beta-Carotene are the most common reasons of nutrition deficiency resulting from an insufficient quantity of fresh fodder. It can be suggested that low concentration of beta-Carotene may be related to hormonal disorders.
