Abstract: Systems and methods for analysing a fluid including a fluid sample delivery application. The system includes a sensing element configured to respond to at least one analyte in a sample of fluid. A detector is provided, configured to sense the response to the analyte by the sensing element. The fluid sample delivery apparatus includes a dosage needle configured to deliver the sample of fluid to the sensing element, at least one pump configured to control flow of fluid through the dosage needle, and at least one actuator configured to move the dosage needle relative to the sensing element. At least one controller is provided, configured to control the at least one pump and the at least one actuator.

Abstract: A method is provided for operating an apparatus for detecting if oestrus is imminent or present in a milking animal, the apparatus configured to be operated by the steps of: a) defining a processing area which encompasses two or more independent heat outputs including a portion of the rear of the milking animal; b) measuring an indicator of heat output from that area with at least one sensor; and c) using measurement obtained in b) to determine if an oestrus condition is imminent or present.

Abstract: The invention relates to a method for detecting mastitis in an animal, characterized by the steps of collecting milk from the animal, and assaying the milk for a substance produced in the animal in an anaerobic environment, and comparing the substance levels obtained with typical substance levels found in uninfected milk.
