Analýza metabolických a reprodukčních ukazatelů ovcí ve vybraném chovu plemene suffolk
OUŘEDNÍKOVÁ, Kateřina
The aim of the study was to analyze the reproductive, productive and metabolic values of ewes from selected parameters in blood, milk and urine in correlation to their metabolic state. The results were used to draw up new breeding and feeding schemes. The research was carried out in 2015, and the sample size consisted of 62 Suffolk ewes. The analysis of reproductive parameters of selected ewes confirms appropriately chosen breeding methods. The average weight of lambs at birth (3,82 kg) is affected by the number of lambs at birth. The average weight of lambs at 100 days of age (32,54 kg) depends on the number of lambs per ewe and the age of ewe. The average daily weight gain makes 0,325 kg per lamb. Lowered concentration of proteins related to the decreased level of urea in the blood plasma signifies insufficient intake of nitrogen of ewes from feed.

Analysis of the Lambing Process in Suffolk Ewes
ŠULCOVÁ, Veronika
The Suffolk is the most well-known of the English lowland sheep breeds. A black-faced sheep with short-stapled wool, the breed is used primarily for meat production. The Suffolk is classified as one of the breeds with the best ability to fatten and its meat yield is approximately 60%. The breed is characterised by its good adaptability to different climate and breeding conditions and overall good health. The ewes are known for their high fertility rate, shorter oestrus cycle, excellent maternal instincts, and high milk production. As a result of these characteristics, the Suffolk has become a very popular breed around the world. This thesis focuses on the breeding of Suffolk sheep as one of the best breeds for the production of slaughter lambs. The thesis also looks at reproduction as a part of sheep breeding, as well as at the factors that have an effect on pregnancy, the birthing process, and the newborn lamb. The main objective of this thesis was to process the lambing data for a specific herd of Suffolk sheep, including performing an evaluation of the basic reproductive indicators, calculating the birth weight of lambs, and determining the ideal age for including ewes in the breeding herd. The basic reproductive indicators include fertility, fertilisation, breeding intensity, and weaned lamb production. In the studied herd of sheep, these indicators were calculated as follows: fertility 182%; fertilisation 91%; breeding intensity 155%; and weaned lamb production 159%. The average birth weight of the lambs was 3.9 kg and the average optimal age for inclusion in the breeding herd was determined to be 17.5 months.

Physiological parameters Suffolk breed of sheep breeding in Soběslav
TOMEČKOVÁ, Andrea
The aim of the thesis was the evaluation of commercial properties, physiological state and selected blood parameters in sheep suffolk breed with focus on monitoring increases, blood parameters and coprological examination which prooved parasitological settlement. Monitoring was conducted in 2013 and early 2014 when 17 ewes and 16 lambs were observed. For thesis purpose two samples were made on 25.3.2013 and 14.10.2013. Several elevated values have been detected among which were glucose, urea, total protein, albumin, 1 and 2 globulin and partially cholesterol. ß globulin was below the physiological range, globulin was initially below the physiological range, but in the second sampling was above the physiological range. Decreased values were observed in case of calcium concentration in blood plasma. The parasitological findings prooved presence of coccidia Eimeria and gastrointestinal nematodes.

The aim of the thesis is to create a technical supportof asheep farm.
KOVÁŘÍK, Tomáš
The aim of the thesis is to create a technical supportof asheep farm. It is the Netřebice collective farm dealing with the crop and livestock production. Currently it deals especially with the production of the cow?s milk, calves rearing and sale of small bulls in the area of the livestock production. The cooperative farm owns 3 grounds. One ground is situated in Chodeč community, it is the biggest producer of the milk and calves. Into the second ground in Milíkovice the calves from Chodeč are beeing transported which grow into adulthood. Small bulls are beeing sold. After reaching their adulthood the heifers return to Chodeč for milk production. The third ground in Dlouhá community was also used for the heifers rearing however by another agricultural society which was in the lease there.In 2010 the agricultural society in Dlouhá finished its heifers rearing and moved into another village. Therefore has the ground been empty and unused since 2010. That is why the collective farm decided to build a project for the new use of the premises for the extension of its livestock production with the sheep breeding based on my thesis. The project is going to focus on the reconstruction of the inner part of the building and the outside of the premises where important adjustments considering both mechanical, construction and technological matters for the sheep breeding are going to be implemented. In conclusion the economic balance of the entire suggestion is going to be built and the total number of pieces of the sheep to stable them in the sheepfold is going to be calculated.

The analysis of Suffolk breed reproduction quality level in a particular herd
JANKOVSKÁ, Gabriela
This breeding have been monitored from 2010 to 2011 to evaluate the effect of rams on the number of fertilized, sterile, pregnant sheep and the number of unborn and dead lambs. The results have been estimated by averaging. In 2010, there were 123 ewes and younger female sheep fertilized and 116 of them remained pregnant. In 2011, there were 145 ewes and younger female sheep fertilized and 140 remained pregnant. Sterility of the sheep, that were fertilized in 2010 by three breeding rams, was on avarage 5,69 % and in 2011 by 4 breeding rams it was 3,45 %. Sterility dropped by 2,24 % in 2011. The percentage of gravidity in 2010 was 94,31 % and in 2011 as many as 96,55 %. And the percentage of fertility is the same as the percentage of gravidity. The number of fertilized ewes and younger female sheep grew by 2,24 % in 2011. When we compare death of lambs right after birth in 2010 the average was 4,21 % and in 2011 it was 5,83 %. Death of lambs in 2011 was higher than in 2010 by 1,62 %. The whole picture of breeding development shows the percentage of fertility. In 2010 the fertility of the herd was 154,30 % and according to the results we can see good breeder's results and the choice of new breeding rams; fertility was increased to 162,79 %. In 2009 it was 148 % and in 2010 was increased by 6,30 % and in 2011 it was raised again, compared to 2011, by 8,49 %. In conclusion, according to the observation and assessment of the particular herd, it is obvious that the breeder successfully increased the fertility of his breeding in comparison to the previous years. Modification in the herd by replacing the rams has been a successful step and it helped to improve the reproduction qualities results and it proves the good feritility of rams in this herd.

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.
