Vliv maedi-visna viru na reprodukční ukazatele ve vybraném chovu plemene šumavská ovce
 OUŘEDNÍKOVÁ, Kateřina
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.

Analýza metabolických a reprodukčních ukazatelů ovcí ve vybraném chovu plemene suffolk
 OUŘEDNÍKOVÁ, Kateřina
The aim of the study was to analyze the reproductive, productive and metabolic values of ewes from selected parameters in blood, milk and urine in correlation to their metabolic state. The results were used to draw up new breeding and feeding schemes. The research was carried out in 2015, and the sample size consisted of 62 Suffolk ewes. The analysis of reproductive parameters of selected ewes confirms appropriately chosen breeding methods. The average weight of lambs at birth (3,82 kg) is affected by the number of lambs at birth. The average weight of lambs at 100 days of age (32,54 kg) depends on the number of lambs per ewe and the age of ewe. The average daily weight gain makes 0,325 kg per lamb. Lowered concentration of proteins related to the decreased level of urea in the blood plasma signifies insufficient intake of nitrogen of ewes from feed.
