The aim of the study is to show some of the main sperm parameters in ejaculates obtained in and out of the reproductive period change. The experiment was conducted with 11 clinically healthy rams of Northeast Bulgarian fine-fleece breed. The collection of ejaculates took place during the natural breeding season (June-July) and out of the natural breeding season (October November). A total of 22 ejaculates were examined for the experiment. Each ejaculate was tested for indicators - motility, concentration and velocity. A higher percentage of total motility and progressively motile sperm is observed in ejaculates obtained during the breeding season. In ejaculates obtained during the breeding season, the percentage of rapid-moving sperm was higher, while in those from the non-breeding period, a high percentage of slow-moving and medium moving sperm was observed.
