Qualitative indexes of milk of ewes the Original Valachian
PEŠINOVÁ, Petra
The aim of study was to evaluate milk efficiency of sheep Original Valachian (OV). Observation took place in the period 2006-2009 and were involved 123 ovine. Samples were taken from the morning milking during the months April to August (method ET). Milking proces was realised mechanically. In 84 sheep were known genotypes AA (n = 13), AB (n = 18), BB (n = 53). After evaluation of essential components of ewe{\crq}s milk from flock of lambing ewes OV during lactation were found these average values: Fat (F) 4,90 g.100g-1, crude protein (CP) 5,94 g.100g-1, casein (CAS) 4,40 g.100g-1, serum protein (SP) 1,18 g.100g-1, lactose (L) 5,07 g.100g-1, dry matter (DM) 16,45 g.100g-1, solid not fat (SNF) 11,63 g.100g-1 and utilizable dry matter (UDM) 10,85 g.100g-1. Average daily milk yield of OV was 0,70 l. Effect of stage of lactation was provable on all the indicators in the level of significance 0,001. It was evidenced a statistically significant effect of the control year on the content of SNF (P{<}0,05), on the L (P{<}0,01) and on all other components (P{<}0,001). At comparing milk production OV according to the genetic polymorphism of {$\beta$}-lactoglobulin have been identified probably significant differences in milk yield (P{<}0,05). The highest daily milk yield reached genotype AB (0,76 l.day-1) {>} BB (0,68 l.day-1) {>} AA (0,66 l.day-1). In AB genotype was found the lowest levels of these essential components F, CP, CAS, DM, SNF and UDM. Highly significant effect of genotype was found on content of L (P{<}0,001). The highest content of L was confirmed by genotype BB (5,13 g.100g-1) {>} AB (5,08 g.100g-1) {>} AA (4,91 g.100g-1). Less significant effect was found on SNF (P{<}0,1). The highest average content of SNF was found in genotype BB (11,72 g.100g-1) {>} AA (11,62 g.100g-1) {>} AB (11,54 g.100g-1). In genotype AA was found the highest values of F, CP, CAS, SP, DM. Both genotypes AA, BB showed the same content of DM (16,32 g.100g-1).

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.

Evaluation of reproductive performance in selected breeding of sheep
BRÁZDOVÁ, Veronika
The aim of this thesis was to evaluate the reproductive performance over the period from 2007 to 2010 in selected Suffolk sheep. The evaluation was carried out on the basis of records kept in the selected breeding sheep at Agris Markvarec s r.o. and on own observations. During the reporting period was evaluated 1115 ewes, which were monitored the following parameters such as fertilization, fertility, intensity, rearing of lambs, infertility, ewes lambing, percentage of sheep abortions, stillborn lambs, mortality, percentage of breeding lambs and percentages of sheep by percent occurrence of the cast. There was also observed age structure of the ewes, the dependence of age on fertility of ewes and the effect of father mother on her fertility. In the observed breeding was found the following results, which are presented as an average over the reporting period, so the percentage of fertilization is 91.2%, fertility 145.2% and rearing 81.3%. The percentage of idleness of sheep is 8.8%, which directly affected the percentage of the intensity, which is 118.3% and the lambing percentage, which ranks lower value 81.2%. A relatively high percentage was achieved in postnatal mortality, which is 11.4%. Percentage of sheep abortions in the average is 5.4% and the percentage of stillborn lambs is 4.9%. Breeding lambs 92.3%. The effect of age of ewes on fertility was confirmed by F - test for the significance level of p ? 0,05. Subsequent testing has been demonstrated median significant differences between groups of ewes aged 2 and 3 years and between age groups 3 and 5 years. On the same level of significance was also demonstrated effects of father mother on fertility of mother and on the basis of the results was found that the lowest average fertility rates in the ewes, their father is out of line Yog (110%) and conversely the highest fertility rate (170,8%) is achieved for mothers whose father is out of line Harald. Further testing, which was focused on the effect of age of breeding ewes and breeding year in terms of the father´s line on the mother's fertility wasn´t demonstrated.

The Utilization Of Goats And Sheep In Care For Landscape And Their Submission In Ogranic Farming
JIRMANNOVÁ, Kristýna
The analysis of management of sheep and goat breeding on the organic farm is the main aim of my thesis. The herd was examine at the Slunečná organic farm in the Šumava Mountains. The animals were monitored during grasing season by force of metod ethology monitoring. Sheep and goats were monitored and it was done four times for always 24 hours during a grazing period. The method of the direct monitoring was used and the base categories of the behaviour (food intaking, lying, standing and moving) were written down by an interval method - the interval took 10 minutes. The comfortable, mother's, social and sexual behaviour were writen down as well. Gained data from single sighting was expressed absolute and percentage share form total tables and graphs. The results were interpreted on the basis of the study of special literature and legislation about organic farming and animal ethology. The way of sheep and goats farming was according to an inborn biorhythm and gave the animal free and natural ways of behaviour. The physiological and ethological needs of animals are satisfactory. Sheep and goats have the possibility to graze freely on pastures and they effect positively on the landscape management. They keep grasslands without woody plants and weeds.

Cryptosporidiosis of small ruminants
UHLÍŘOVÁ, Barbora Isatou
Cryptosporidium (Apicomplexa: Eucoccidiorida: Cryprosporiidae) is a ubiquitous entero-pathogen and has been reported in many geographical regions of the world. Cryptosporidiosis is a zoonotic protozoan disease of worldwide distribution, affecting a wide range of vertebrate hosts. The parasite is recognised as one of the most common causes of diarrhoea in humans and farm animals. There are 23 valid species of Cryptosporidium so far and over 60 genotypes with no species names have been described. Cryptosporidial infection of livestock may have an important economic impact on farmers because of high morbidity and mortality rates among animals. The present study is undertaken to describe problem of cryptosporidiosis of sheep and goats.

The growth of valaška lambs
JENÍČKOVÁ, Jana
The aim of my diploma work was to evaluate the gains in weight of Walachian lambs based on origin of individual groups of ewes and paternal lines. Based on distribution in accordance with origin of mothers we can say that the biggist weights dutiny weight checks had lambs coming from eves imported from Germany. When comparing average gains in weight in accordance with paternal lines, there is evidence of prevailing bigger achieved weights of Juráš line.

EVALUTION OF PASTURE GROWTH OF SELECTED FARMS IN SOUTH BOHEMIAN BORDER AREA IN RELATION TO AGRICULTURAL ACTIVITES
SLÁMOVÁ, Kateřina
Annotation Topic: The rating of pastoral vegetation of selected farms in the south bohemian borderlands in relation to agricultural activities In my bachelor thesis I dealt with the rating of pastoral vegetation of selected farms - The firm Agroteta MM, s.r.o., which is dealing with the breeding of the Czech mottled cattle located in Rychnov nad Malší and the farm of Mr. Jan Vejčík, which deals with the breeding of the ennobled Valaška and the Bohemian Forest sheep. This farm is located in Dlouhá Stropnice. The goal of this thesis, based on my own observation and available data, was to find out and proof the differences in the way of the management of the grasslands, which express themselves in the structure and the generic composition of the vegetation, especially in relation to the stressing of the grasslands and their use. The results show, that the cattle-range is having one-sided positive effect, regarding the overall environment, it has a positive effect on the fauna and flora, and also the economical aspect.
