The subject of this dissertation was the analysis of the influence of selected breeding dairy elements on the technological properties of their milk. The monitoring took place from October 2012 to October 2013 (53 weeks) for a total of six milk suppliers within the Vysočina Region. During the experiment, a total of 318 milk analyzes were analyzed in the Agricultural and Analytical Laboratory in Pribina Pribyslav and 172 sample analyzes in the CL (Central Laboratory) Buštěhrad. The breeding environment has been monitored continuously, in particular in stables and temperature and relative humidity outside the stables. The observed parameters of the breeding environment were the temperature in the stable, the outside temperature for comparison and the relative humidity. Milk suppliers were selected based on the breed dairy breed, dairy cradle and milking method. It has been shown that the milking method of dairy cows (milking parlors, cans and piping) had a statistically proven effect on milk constituents. The fat content was statistically significantly lower in case of milking in milking parlors than milking in pipes and hoses. The content of proteins and dry matter had the opposite trend, ie higher milking milking and lower milking content in cans and pipes. This fact was confirmed in the further analysis of the data, according to the conditions of the housing, when the same situation was repeated. The influence of the accommodation method on the temperature conditions in the stable was demonstrated, and the temperature at the stables was clearly higher, which ultimately had a significant impact on the cheese's curdiness and quality, as described above. The influence of the milking method on the microbial load of milk has been demonstrated. The lowest values were recorded during milking in the milking parlor, either CPM (total number of micro-organisms), number of coliform bacteria or SB (number of somatic cells)

The aim of the work was to analyze the issue of agricultural land a orestation by fast-growing trees and to explore the soil environment in relation to the ecological and growth demands of the Paulownia in terms of soil physical properties. The subject of the work was the area of the plantation on agricultural land with the planting of Paulownia (clone in vitro 112) from the years 2016, 2017 and 2018 near the village of Střelice u Brna. Data gathering was focused on the physical properties of soil in terms of water and air mode and compaction. The basic soil chemistry obtained data will be given for the evaluation of growth conditions. The resulting data were statistically evaluated and the results were presented using appropriately designed tables and graphs. The charts were supplemented with comments and evaluated. The results revealed suitability of researched soil environment of aspect of chemism while the physical properties became evidently insu?cient. In addition to soil environment also the climatic conditions were found critical for Paulownia planting. Although the climatic data collection was not direct subject of this research I found – on the base of ?eld investigation – I can state their unsuitainability for Paulownia cultivation due to frost threat.
