Systems and methods for analysing milk are described. A plurality of First Type Sensors (FTPs) are provided, each associated with a respective one of a plurality of Milking Clusters (MKs) of a milking system and configured to analyse milk extracted from an animal by the MK to determine at least one FTP value of a parameter of the milk across an event period. At least one of a Second Type Sensor (STP) associated with at least one of the plurality of MKs is configured to analyse the milk to determine at least one STP value of the parameter within the event period, wherein the STP is less susceptible to animal specific bias than the FTP. An Animal Specific Bias Correction (ASBC) is determined based on the at least one FTP value and the at least one STP value and applied to FTP values for milk extracted from the animal.
