Vyhodnocení masné užitkovosti u vybraných plemen ovcí
MAZOUROVÁ, Nikola
In mountain and foothill areas, sheep farming is very suitable in the agricultural sector. Its popularity is still growing, and its enormous advantage is that sheep graze the land even in hard accessible areas and thus contribute to landscape maintenance. The aim of the bachelor's thesis is evaluation of meat efficiency of two selected meat breeds of sheep in a selected breeding. It is focused on Suffolk and Charollais breeds. To achieve this goal, a set of data obtained from yield control database SCHOK (Association of Sheep and Goat Breeders), based on which the meat efficiency was evaluated. Specifically, these were average daily gains, weight in 100 days, muscle height and fat in 100 days. Subsequently, the obtained data were compared to the literature and with data of the national average from KU (efficiency checks).

Vyhodnocení produkčních vlastností ovcí plemene suffolk a charollais v ekologickém chovu
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.

Problematics of meat sheep breeds
Picurová, Daniela ; Ptáček, Martin (advisor) ; Nohejlová, Lenka (referee)
Bachelor´s degree thesis has been elaborated as a literature review of accessible specialised sources. It dealt with a sum of recent findings concerning the breeding the meat-producing races of the sheep, which is rapidly developing after 1990.
Introduction established the structure of sheep races bred in the Czech republic and their classification according to the production performance. The thesis is focused on meat-producing races of the sheep, the most important among them being characterised verbosely. Within the frame of the thesis topic, the performance features were defined. The main part of the thesis dealt with the meat production performance and breed reproduction, which affect the breeding economy.
The aim of the thesis was to determine the major factors influencing reproduction and production properties of the breeding material. We have found out, according to specialised literature, that breed, sex, number of lambs per brood and the fattening manner produced the significant effects on the live weight of lambs. The body condition score of mothers had no significant effect in the time of gravidity. The results of the studies indicate that live weight of mothers, age of mothers and lambing season affect significantly the vitality of lambs and their growing disposition consequently the breed economy. Based on the available literature it seems to be an interesting issue early breed ewe lambs, a category that has not been adequately studied. It would therefore be potentially interesting to examine this issue further.

Seasonal dynamics of selected blood parametres of selected flesh breeds of sheep bred in foothills conditions
ŽÁČKOVÁ, Klára
Sheep breeding is nowadays a developing branch of agriculture again. There is a lot of different breed and they react distinctly on the same conditions of the enviroment. Sheep of breeds charollais, suffolk, šumavská ovce and valaška bred in similar conditions were observed in spring and autumn of years 2007 and 2008. In these seasons were taking blood samples (from {$\pm$}7{--}24) ewes and lambs and were analyzed in hematology laboratory. There were determined haemoglobin level, haematocrit indicator, erytrocytes and leucocytes levels, glucose, cholesterol, triglycerides levels, urea and plasmatic proteins, activity of ALP and GMT enzymes, phosphor, calcium, magnesium, zinc and copper levels. The main objective of this project was determine seasonal changes in observed parametres. Next objectives were determine different changes in blood parametres in different breeds and different aimes of breeds. There were recognized that all the observed breeds don`t react the same way on similar conditions. There were not provably determined seasonal changes in observed parametres, but average Hb level was higher in autumn than in spring. Urea level was conversely higher in spring season than in autumn. The demostrable fact is, that the similar conditions induce different answers not only in different breeds but also in different aimes of breeds.
