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.
