Evaluation of the breed of sheep production Merinolandschaf
KRÁLOVÁ, Lucie
The aim of this work is to evaluate the levels of production traits in sheep breed Merinolandschaf. Evaluation of the effect of selected factors on commercial properties in the herd of the breed. This thesis mainly focuses on the effect of age ewes, rams line at impact, influence the frequency of newborn lambs on production indicators. The evaluation of these properties were used data from performance tests and evidence from past years. The thesis should clarify some advantages in breeding should point out shortcomings and problems that occur in the breed while providing solutions to improve the situation in the selected breed. In 2009, the percentage of fertilization to the lowest value of 77.1. The performance tests from 2006 to 2012, we can see that the percentage of fertility by 2010 rising, thanks to the experience breeder. Average intensity of the years 2006 - 2012 was 120.9%. Thanks to the year 2009, the average number of weaned lambs from ewes low number of 107%. Minimum number of weaned lambs in 2009 and to 77.1% and the maximum number was reached in 2010 - 123,4%. Average weight of lambs at birth breed Merinolandschaf for the period was 3.41 kg and 100 days of age 22.55 kg. When comparing fertility ewes depending on their age were detected statistically significant differences at the level p < 0.001 yen sheep aged 5 and 7 year olds. When evaluating the impact of fertility ewes depending on the line of ram, a statistically significant difference at moderate level of p < 0.001 > 0.01 MACEK between lines and between the lines and MESTEK MAGOR and MESTEK. Highest percentage of sheep with singleton was achieved in 2010 and the lowest percent in 2009, while in 2009 it achieved the highest percentage of sheep with twins and multiple litters. Based on the results it can be stated average level of breeding. About this fact testifies above all to achieve reproduction indicators, which were compared with countrywide results.

Evaluation of production characteristics of sheep breeds merinolandschaf
KRÁLOVÁ, Lucie
Evaluation of production characteristics of sheep breeds merinolandschaf were compared with results of performance tests of the reference density to the national results. The results of the performance tests can indicate that the percentage of fertilization in animals was monitored until 2007, the average fertilization throughout the Czech Republic and since 2008 the percentage of fertilization on the contrary decreased. Fertility percentage over the period from year to year increases. In 2006 the fertility rate was 121,5 % in 2010 it was already150,8 %. The average for the period was 137,7 %. Average intensity (the ratio of the number of lambs born to ewes in the number of reproduction) between the years 2006 to 2010 it was 121,6 %. Raising the reference breed merinolandschaf was on average 105,84 % in a five-year period. From the control performance arises that the weakest year for rearing was the year 2009 with only 77,1 %. Shearing of the wool at the reference density in 2007 was 3,49 kg and in 2008 - 3,7 kg. The diference between the weight of the wool was 1,31 kg in 2007 and in 2008 it was only 0,3 kg in favor of the nationwide results. On average, each year in the replacement of the years 2006 - 2010 Paseky included in breeding ewes 73,8 ewes, were pregnant was 64,4 pc and 9,2 pc reactive. In 2006 it was achieved the best results by the number of lambs weaned (zero deaths). On the other hand, in 2009 there was a large number of sheep deaths (25 dead lambs). On average per year was reared during the reporting period, five lambs of 76,4 and 81,8 live births lambs overall average of 89 lambs. The weight of lambs at birth followed a five-year period was on average 3,44 kg in 100 days and 22.15 kg. From the results obtained from performance tests from 2006 - 2010 arises that the combined merinolandschaf breed is suitable for possible use as a maternal race in the production of slaughter lambs.
