In this bachelor thesis, the influence of the external environment on the milk performance and behavior of Holstein cattle in a particular company was used, using the technology of robotized milking from Lely. The subject of observation was mainly the average daily milk yield, the order of lactation, the time and frequency of milking depending on climatic conditions. The data were continuously collected during 2018. It has been found that the external environment significantly contributes to the milk performance of cattle. Among the proven influences was the order of lactation, which mainly contributes to the daily production and milking speed. In addition, the season of the day, when daily production, milking rate and milking frequency varied depending on temperature, was followed. The research revealed that dairy cows reach the highest production in the second and third lactation. Furthermore, the influence of the external environment significantly affects the daily production of dairy cows and the speed of milking. |
