The aim of the thesis was to evaluate the influence of maedi-visna on reproductive indicators in selected Šumava sheep breeding. Serological test ELISA was accomplished in the evaluated herd, and its results were used for comparing reproductive rates of healthy and infected ewes. Maedi-visna disease was proved in 16 out of 193 samples (8, 29 %). Statistically significant influence of maedi-visna was shown in indicators such as age of infected ewes and number of reared lambs. For other indicators (number of live birth lambs, lambs weight in 100 days, occurrence of sterility, mortality and stillborn lambs) higher success rate was observed in maedi-visna negative ewes, however these findings were not statistically significant. Maedi-visna is incurable disease and most important tool how to avoid this disease is preventive protection of the sheep breedings.
