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.

Producing, selling and processing sheep wool (South Bohemia)
KOVAŘÍK, Petr
The bachalor thesis is focused on difficulties with wool sales. In the last years, sheap shearing was sometimes only an animal welfare activity with no profit for the farmer. The aim of the thesis was to analyse the conditions under which the wool from the South Bohemian farmers is sold to the wool buyers. The thesis was also focused on altenative uses of fleece, that would have assured greater demand even for medium and coarse wools. The thesis describes history of sheep husbandry, current state of sheep farming in CR, and wool uses examples. It also charts the wool bueyrs and wool processing companies. The conclusion is dedicated to the new form of wool use, which allows using low-grade and coarse wool.

The thyroid gland activity of sheep
DŘÍZHALOVÁ, Blanka
In the theoretical part of my thesis, I describe the thyroid, its importance, anatomy, creation of hormones and their regulation. There is also summarized the knowledge of external environment influences on the thyroid such as nutrition, climatic conditions or seasons and internal factors influences, mainly breed, efficiency and age. The practical part is focused on the evaluation of the thyroid activity of free-range ewes and lambs in the spring and autumn of 2013. The thesis also deals with the evaluation of possible relevance between the content of thyroid hormones in the blood serum and the physiological state of the sheep. Thanks to the correlation between TSH and thyroid hormones, the proper regulation of the thyroid of ewes and lambs was confirmed. The thyroid activity was higher in the spring than in the autumn. The hypothyroidism in the autumn was not proved because no referential values of TSH are set. In the autumn there was a lower level of glucose and cholesterol in the blood of the ewes determined which gives evidence of a lower energy income from the feed in the autumn. Also the urea level which is closely connected to the energy shortage, starvation, and high income of N substances in the feed dosage was in the autumn twice as high as in the spring. There was a positive correlation determined between the higher urea concentration and the higher thyroid activity. Owing to the change of the feed content, the TSH started to stimulate the thyroid to a higher thyroid hormones production and thus to its higher activity.

Qualitative parameters of erythrocytes in selected animal species
BÖHMOVÁ, Václava
The goal of the thesis is to evaluate the haematologic indicators of red blood cells depending to the physiological condition and yield of cattle, sheep and dogs. The evaluation of qualitative parameters of red blood cells included 59 dairy cows, 57 meat cows, 62 sheep and 73 dogs. The evaluation of the haematologic parameters of cattle was performed based on the production (yield) type and by season; that of sheep, by season, age and sex of lambs; and that of dogs, by sex, age and size - weight. The yield types showed statistically significant difference between the number or erythrocytes, haematocrit, haemoglobin, MCV and MCH concentration. The dairy cows showed seasonal fluctuations of the number of erythrocytes, haematocrit and haemoglobin; the meat cows showed fluctuations of the haemoglobin, MCH and MCHC values. The age influenced higher values of erythrocytes in sheep and lower values of MCV and MCH in lambs. The sex of lambs did not lead to significant differences. The evaluation of dogs by age showed differences of haematocrit and haemoglobin values. The dog size (weight) and the sex did not have demonstrable influence on haematologic values. Anaemia was found in 36 % dairy cows (it did not occur in meat cattle) and in 2 sheep (3 %). By most authors, anaemia was not found in dogs.

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.

Housing technology and its impact on the welfare of sheep breed Valaška.
LIŠKA, Zdeněk
The aim of the bachelor thesis was to evaluate the technology of sheep housing and its influence on their welfare. To evaluate the given technology, the control monitoring of the flock was carried out and the local veterinary and zootechnical documents were used. The other sources of information were farmer´s records. For breeding the flock, the year-round rearing on pasture with a free access to the stable is applied. Based on the monitoring and evaluation of the data obtained, it was found that the technology is optimal in terms of welfare and health of animals. Furthermore, it was found that the technology of sheep housing is favourable in terms of operating costs and labor requirements. Key

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.

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.

Endoparasite infections in sheep and goats in diverse farming systems
UHLÍŘOVÁ, Barbora Isatou
Samples of excrements for parasitological investigation were obtained in two year period 2011 and 2012 on three sheep farms and two goat farms in South Bohemia (a farm conventional, an organic and converting to an organic farming system). A total of 400 samples were examined using four parasitological methods. Thirteen species of gastrointestinal nematodes and one species of Protozoa were recovered. In farms Coccidia Eimeria spp. was the most diagnosed. Results revealed that goats were 1,8 times more often infected with parasites than sheep (x2 = 6,274; d. f. = 1; p = 0, 00576; OR = 1,82). Animals younger 6 months were 3 times more often infected with Eimeria than older ones (x2 = 17,174; d. f. = 1; p = 0,00003; OR = 3,16). Goats were 11 times more often infected with parasites in winter than sheep (x2 = 5,8174; d. f. = 1; p = 0,0050; OR = 10,78). Goats were 2 times more often infected with lungworm infection than sheep (x2 = 8,407; d. f. = 1; p = 0,0019; OR = 1,99). A statistically significant difference in infectious contamination between conventional and an organic system bred animals was not discovered (x2 = 0,0145; d. f. = 1; p = 0,452; OR = 1,05).
