The comparison of two breed of sheeps reared in the same area. The aim of the master thesis was the evaluation of the level of the reproductive and the productive traits by the two breeds of sheeps in the area of Novohradské Hory Mts. The examination was conducted from 2006 to 2009. The farm recording and the author´s personal observation were both used for the evaluation. The following traits were recorded: insemination, fertility, intensity, lamb rearing, infertility, mortality. The production traits recorded were the weight of the wool and weight gain in 100 days after the birth. The following results (arithmetic means) were obtained: the rate of insemination by the Valaška breed was 94.3 %, fertility 168.4 %, intensity 158.5 % and the lamb rearing 150.2 %. The rate of infertility was 5.9 % and rate of mortality 5.1 %. The average wool weight was 2.21 kg and the weight gain 175.8 g day-1. By the Merinolandschaf breed, the rate of insemination was 87 %, fertility 134.4 %, intensity 116.1 % and the lamb rearing 101.5 %. The rate of infertility was 13.2 % and rate of mortality 8.8 %. The average wool weight was 4.2 kg and the weight gain 236.9 g day-1. The herd A revealed better results as regards the reproduction traits while the herd B revealed better results concerning the production traits. The significant differences between the examined herd of Valaška sheeps and the Czech population were found in the fertility, intensity and the lamb rearing (T test). By the Merinolandschaf herd, the significant differences from the Czech population were found by the weight gains (T test). The significant differences between the two breeds were found in the fertility, intensity and lamb rearing (T test).
