Robotic milking systems (RMS) modify dairy herd management and therefore some aspects of production. The mainresults from scientific literature on RMS and cheese-making properties have been reported. The decrease in fat content,as a consequence of the increased milking frequency, is generally confirmed. The lack of specific studies on creamingproperties of milk from robotic milking experiences and with different milking frequencies has been highlighted.Indications on clotting features were obtained with a different milking frequency in a traditional milking parlour; theseresults showed an improvement in the casein index of milk from three daily milkings. A reduction of casein exposure tothe plasminogen-plasmin complex activity in the mammary gland between two consecutive milkings seems to explainthis result. The effect of RMS on milk quality for cheese-making purposes was first evaluated in a two-year monitoringstudy in a herd representative of Po Valley dairy farms. Preliminary results from laboratory tests on bulk milk samplesindicate that milk from RMS seems suitable for cheese-making processes.
