VOSTŘÁKOVÁ, Veronika
The aim of this diploma thesis is to evaluate production characteristics of two breeds of sheep: Suffolk and Charollais. Data for evaluation of characteristics were received from the performance control in years 2016 - 2019. This data were afterwards compared with the nationwide results. This thesis focuses mainly on fertility, fertilization, rearing, number of sheep in reproduction, intensity, evaluation of growth capacity of lambs after birth, death rate of lambs and the difference in number of sheep with single lambs, twins, triplets and quadruplets. In 2016, the average fertilization of the Suffolk breed was 94.1%. In 2016, the percentage of fertilization in the Charollais breed was 97.2%. In comparison with the national results, the average fertilization on the Bočan Farm is higher, in the Suffolk breed by 4.9%. The average fertility per ewed sheep from 2016 - 2019 in the Suffolk breed was 147.4%. The average fertility of the Charollais breed was 159.3% during the observed period. The average intensity in the Suffolk breed was 142.5%. The lowest intensity was in 2016 - 129.4%. The highest intensity of the Charollais breed was reached in 2017 - 164.6%. Another value observed was the weight of lambs after birth and at the 100th day of age. The average weight of Suffolk breed ewes after birth was 2,87 Kg, for rams it was 3,04 Kg. The average weight in the Czech Republic, during the measured period, was 3,1 Kg. The lowest weight of ewes at the 100th day was 28,40 Kg in 2016. The average weight of rams was 30,49 Kg. The lowest weight of Charollais breed ewes after birth was reached in 2019 with value of 2,89 Kg. The highest weight of rams was reached in 2018 with value of 3,27 Kg. The average weight after birth in the Czech Republic is 3,3 Kg. Another parameter monitored was the death of lambs. The most dead lambs in the Suffolk breed were in 2019 - 12 pieces, in the Charollais breed there were the most dead lambs in the year - 2018 - 25 pieces.
