Method and device for detection of a deviating behaviour of a milking animal

A device for detection of a deviating behaviour of a milking animal (101) during milking procedure in an automatic milking system (100), said milking procedure comprises at least one sequence, said system comprising

• an automatic positioning device (105) having a process for positioning animal related means (106),
• means for identifying said animal (101), and
• means to retrieve information related to said animal (101) from a memory (111) in a computer (110), said information comprising at least one reference value derived from at least one sequence of a previous milking procedure,
• characterised in that said device further comprises:
• means to register at least one value, related to said automatic positioning device (105), from said at least one sequence of the present milking procedure,
• means to compare each reference value with each registered value in an analysing means (112) in said computer (110), and
• means to issue a warning signal from said computer (110) if any of said registered values deviates from the corresponding reference value more than a predetermined deviation value from each corresponding reference value,
• whereby the device for positioning the animal related means (106) is used for determining if the milking animal (101) deviates from a normal behaviour.
