To evaluate the impact of a new technology in dairy production (the change in the production system and milking technique), we analysed the production and milk quality parameters data of a conventional Slovenian dairy farm. We analysed three periods: intermediate period, and the period before and after the introduction of the automatic milking systems (AMS). No significant differences were observed in the amount of milk quantity. The analysis of data showed significant differences in the following parameters: fat, protein, lactose and somatic cell count. The levels of fat, protein and lactose were significantly higher. The number of somatic cells was significantly lower after the introduction of the AMS.
