Arrangement (100) evaluating performance of milk dosing arrangement (105)/lateral flow stick (110). The arrangement (100) comprises: the lateral flow stick (110) arranged to indicate a biomarker in a milk sample. The lateral flow stick (110) comprises sample pad (210), conjugate pad (230), indication zone (250) and porous membrane (240). The milk sample is applied to the sample pad (210). A camera (120) is directed to capture an image (300) of the lateral flow stick (110). A controller (130) is configured to instruct the camera (120), to capture the image (300); receive the captured image (300); define a first area (310) of the image (300) of the lateral flow stick (110), substantially depicting a subsection of the porous membrane (240) upstream the indication zone (250) in the flow direction; apply image processing on the first area (310); evaluate performance of the milk dosing arrangement (105) based on the image processing.

A rotary milking platform (3) comprises a plurality of stalls (5) and an RFID animal identifying system (9) for identifying animals entering the stalls (5) of the platform (3). A microprocessor (14) reads signals from an image capturing device (15) and computes a feature vector from the captured image of each animal. A plurality of reference feature vectors comprising respective matrices of metrics already derived from images of the respective animals captured by the image capturing device (15) are stored and cross-referenced with the identity of the respective animals. The microprocessor (14) compares computed feature vectors of each animal with the stored reference feature vectors until a best match has been determined with one of the reference feature vectors. The identity of the animal of that matching reference feature vector is then determined as the identity of the animal of that computed feature vector. The determined identity of the animal in the relevant stall (5) is compared with the identity of the animal determined for that stall (5) by the RFID system (9). On a favourable comparison the identity of the animal determined from the captured image of that animal is confirmed as the identity of the animal. In the event of a conflict between the two identities being determined, a conflict alert signal is produced.

A milking system for sampling and analysing milk includes a milking device, a sampling device to extract a milk sample, and an analysis device for the sample. The analysis device includes a cassette with an analysis tape having a carrier layer with separate vertical flow analysis pads, a tape displacer, a sample provision device providing a droplet of the sample to a selected analysis pad, a sensor to sense a response in the analysis pad after provision of the sample, and a control unit. The analysis pads include a reagent pad with a reagent reacting with a predetermined compound in the sample, a priming pad with a priming agent to change a property of the sample that enhances the reaction, and a bonding layer between the reagent pad and the priming pad, and including a first and second adhesive layer, and a support layer therebetween.
