Tepelné podmínky v chovu dojnic

The main subject of the bachelor's thesis "Heat conditions in dairy cows" was to elaborate literature on the topics of micro-climate, individual requirements of cows for microclimate factors, effect of heat stress on breeding and physiological state of cows and its subsequent elimination. The influence of thermal stress on mastitis of cos was also studied. The main focus on the possible elimination of heat stress was on evaporative cooling, different variants, activation temperature, construction and its parameters. Finally, the calculation of the economic loss due to thermal stress with reduced efficiency was made. Microclimate conditions in dairy cows breeding play a key role in providing suitable conditions for dairy cow performance and its welfare. From the point of the microclimate view, the temperature humidity index is considered, which, together with the air velocity, determines the thermal perception of the state of the environment. Generally this state is expressed by the temperature humidity index (THI)
