Performance and reproduction of Holstein cattle
KAMENÍKOVÁ, Jana
The aim of thesis was to analyze the milk efficiency and fertility of dairy cows of Holstein cattle breeding under intensive conditions. The examinations were made in the agricultural company ZDV Krchleby, a.s. during the year of 2007 to 2009. In total, 147 dairy cows were used for observation including 35 Holstein dairy cows (100% H, R 100%), in a group called - H1, 70 Holstein cows crossed with Czech spotted cattle (H 75 - 87%, R 75 - 87%) in group - H3 and 42 Holstein cows crossed with Czech spotted cattle (H 50 - 74%, R 50 - 74%), in group - H4. Furthermore, the basic data set was divided according to lactation into four groups: 1st lactation, 2nd lactations, 3rd lactations, 4th and more lactations. The main indicators for evaluation of the milk efficiency were the: milk quantity (kg), amount of fat in the milk (%), production of the fat in the milk (kg), amount of protein in the milk (%), production of protein in the milk (kg), content of lactose in the milk (%), persistency of lactation and lactation duration (in days). In terms of fertility, the following factors were evaluated: the cow?s age at first birth (in days), insemination interval (in days), service period (in days) and the periods between births (in days). The cows in the first group milked on average of 8945.03 kg of milk, the amount of fat was 3.66%, the content of protein was 3.32%. Cows in the second group milked an average amount of 8186.55 kg of milk, the content of fat was 3.77%, the amount of protein was 3.33%. The third group milked an average amount of the milk 8649.05 kg, the content of fat was 3.58% and the amount of protein was 3.26%. Differences between these groups were not statistically significant. From the reproductive indicators, statistically, the only most significant difference was the time in between births. The longest period in between births was measured in the first group - 576.22 days, in the second group - 487.38 days and in the third group - 480.95 days.
Evaluation microclimate in dairy farming in chosen enterprise and proposal for improvement.
VACUŠKA, Josef
The substance of this bachelor work is mainly to evaluate microclimate in dairy farming and to suggest ways for it{\crq}s improvement. Dairy farm is located in chosen enterprise. The work describes characteristics of temperature, moisture, wind{\crq}s speed in chosen stable and it{\crq}s impact on animals. Next step was to propose the ways which could that microclimate adjust on values, in which animals are felling well.

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.

Iodine content in excrement. Calibre was locate from 430 {$\pm$} 142,4 {$\mu$}g {$\bullet$} kg-1 bis 6182,5 {$\pm$} 2625,6 {$\mu$}g {$\bullet$} kg-1 dry matter and average 2299,2 {$\pm$} 884,3 {$\mu$}g . kg-1 dry matter. Relation was low from between idoine content in excrement and iodine reception. Environment was not contaminate.
The analysis of the beef breed charolais with the regard to the animal welfare
VRCHOTOVÁ, Klára
The aim of this work was evaluate the productive indexes and appreciate the behaviour of beef cattle dams reared in the system of breeding cows without market milk production. The analysis of the beef herd was performed in the agricultural company farming in above sea level altitude 650 meters. Through the years 2001 - 2006 was evaluated reproduction indexes by dams of basic herd and calves growth ability. Ethological monitoring was important for appreciation welfare conditions of breeding. Monitoring went ahead in single yearly periods in luminous parts of the day. Tracked group formed 31 pieces of dams, calves and sire.
