In this work was studied small typical cowshed’s(100 units) workers work conditions in a point of view of work heaviness, microclimate and noise conditions. A heaviness of various works (feeding, milking, manure removal) was studied with theoretical calculations and with experiments. For this experiment was used a research method of human’s organism physiological changes – a measurement of heart’s pulse. A thermal environment was evaluated in autumn and winter periods. When the measurement in a cowshed was finished, was established the fact, that the most hard work are animals feeding. According to International work organization, this work can be ascribed to hard works group (pulse 125 – 150 min-1). Thermal environment in cowshed is very unfavourable to human’s organism, because in autumn period temperature is 8 - 12°C, and relative moisture in all seasons in a place of milking is 90 - 100%, and speed of weather moving in a different places was from 3 to 9°C. When a noise in a cowshed was studied, was established the fact, that a noise, which have an effect on worker, do not overdraw ground 80 dBA limit.
