The aim of the thesis: Assesment of Parameters of Microclimate in Rabbit Breeding is to make a measurement of microclimate parameters cage housing on a private farm in Velke Nemcice. Part of the work was focused on breeding technologies, namely technology of housing, feeding, watering and removing feces. The highest daily average temperature was recorded in July, when it reached 25.22°C. The lowest daily average temperature was measured in January, when it dropped to 9.31 ° C. In the investigated breeding the most readings of relative humidity reached values between 60-70%. The concentration of carbon dioxide content varied from 0.04 vol.% to 0.009 vol.%. The ammonia concentration in the living zone was about 6-8 ppm. The largest number of live births were recorded in February, when the 11 rabbits born with highly significiant effect (t-test - 0.005). Growth ability can be evaluated in the context of the season highly statistically significant differences in animals up to 5 weeks of age.

The purpose was clarification of vertical stratification of temperature and humidity in winter rape and winter wheat canopy and their comparison with the data from standard station. Air temperature and relative humidity was monitored in wheat and rape canopy in Žabčice during the main growth season in 2010 and 2011 years. Automatic sensors were positioned at three levels (on the ground, at the effective height and at 2 meters above the ground). According to crop developmental stage period was divided to three (four) parts. Air temperature and relative humidity in vertical profile of canopy differed significantly in dependence on year, wheat or rape developmental stage and time of day. The differences in vertical stratification of air temperature and relative humidity were pronounced especially during the light part of the day. In this time the temperature in ground part of canopy was significantly lower and the relative humidity was significantly higher. Air temperature measured in wheat or rape canopy was compared with data from standard meteorological stations, also. The results can be used in precision of prediction methods of some harmful agent's occurrence.

Target is to explore, if homeopatics or another unconventional ways could be used in medical treatment or in prevention of cow mastitis, and at the same time to find by the mesurement of microclimatics indicators if the climate in stable has influence on inflammations of lacteal gland.

Ammonia production associated with animal husbandry is important not only in terms of microclimate of stables, but also in terms of its impact on the environment and buildings located near the farms. Different approaches are applied to limit the production of ammonia and the negative effects on animals. The final effect of the measures involve a number of factors, which requires special technological equipment. It has been designed process for evaluating the binding ability of ammonia in clay minerals. It was detected that clay minerals with a smaller fraction had quicker efficiency compared to larger fractions. However a smaller fraction is associated with a higher dust, which is becoming a limiting factor. Application of biotechnological preparations in stables for fattening chickens showed that low pressure nebulizer device can be used not only for adjusting the relative humidity of air and for the application of biological products, which reduce the amount of ammonia in the stable. High or low pressure spraying have been tested in pig and poultry. The nebulizer device may be a tool to reduce the temperature in the barn. The dose and concentration of the specimen as well as the interval of application of specimen and placement of the nozzles in the stable area are important for the elimination of ammonia. The system can be recommended to well-insulated stables, where the short term reduction of ammonia in the stable air may be expected. Based on the results of measuring the effectiveness of biological air washer in pigs, the rise time of the device depends on active microorganisms on surfaces and can take depending on the microclimate parameters more than 3 months. Biological washing of air is sensitive to environmental conditions, which should be constant. When changing the water intended for circulation of air in the machine and ensure its effectiveness, it is recommended to change only one third, compared to one-half that is recommended by the manufacturer. The biological air washer helps to significantly improve air quality in the stables. Moreover, the loss of nitrogen is eliminated.

The influence of the concurrent land-use changes that took place in East-Germany from the Thirties to Eighties on micrometeorological conditions is examined. These land-use changes lead to a slightly warmer and drier atmospheric boundary layer (ABL). Moreover, they may significantly modify the partitioning of incoming energy between sensible and latent heat as well as partitioning of cloud-microphysical processes between the warm and cold path of precipitation formation. The atmospheric response to concurrent land-use changes deviates from superposition ( of the responses to simple land-use changes) also in areas of nonsignificant changes. / Der Einfluss der akkumulierten Landnutzungsänderungen, die zwischen den 30-er und 80-er Jahren in Ostdeutschland stattfanden, auf das Mikroklima wird untersucht. Diese Landnutzungsänderungen führen zu einer geringfügig wärmeren und trockeneren atmosphärischen Grenzschicht. Die Aufteilung der einfallendenden Energie in Flüsse fühlbarer und latenter Wärme sowie der wolkenmikrophysikalischen Prozesse in den warmen und kalten Pfad der Niederschlagsbildung ändern sich signifikant. Die atmosphärische Response auf die akkumulierten Landnutzungsänderungen weicht auch in Gebieten ohne signifikante Änderungen von der Superposition der Auswirkungen einfacher Landnutzungsänderungen ab.
