Milking arrangement at farm

An arrangement comprising:

• A) a milking entity configured for milking all animal individuals of a first group of animals substantially simultaneously and/or successively at a milking session, wherein the milking entity comprises:
• i) a plurality of milking positions, each milking position comprising a milk extraction device and being configured for milking one animal individual at a time in a respective milking event;
• and
• ii) a milk passageway arranged to transport milk from the plurality of milking positions towards a milk storage tank;
• B) an animal identification system configured to identify in which one of at least the first group of animals and a second group of animals an animal individual belongs;
• C) a milk analysis device is configured to obtain a plurality of milk samples from the milk passageway, the milk analysis device being configured to perform a milk analysis, to measure a biomarker of milk or a constituent in milk of individual milk samples of the plurality of milk samples, and to provide a value of the measured biomarker or the measured constituent for individual milk samples of the plurality of milk samples;
• and
• D) a control arrangement configured to:
• obtain an animal identity of a respective animal individual being milked at the milking session in the milking entity from the animal identification system,
• obtain or generate at least one timestamp for the milking event of each animal individual being milked at the milking session in the milking entity,
• determine whether a respective animal individual being milked at the milking session in the milking entity belongs to the first group of animals,
• store a first timestamp corresponding to the first animal individual of the first group of animals being milked at the milking session in the milking entity,
• determine whether a respective animal individual being milked at the milking session in the milking entity is a first animal individual that belongs to the second group of animals, and, when the respective animal individual being milked at the milking session in the milking entity is the first animal individual of the second group of animals, store a second timestamp corresponding to the last animal individual of the first group of animals being milked at the milking session in the milking entity,
• obtain or generate a milk sample timestamp for each milk sample of the plurality of milk samples,
• obtain the value of the measured biomarker or constituent for individual milk samples of the plurality of milk samples from the milk analysis device,
• assign a group score to the first group of animals based on the values of the measured biomarker or constituent for the milk samples with milk sample timestamps within a time period from the first timestamp to the second timestamp.

An arrangement for use at a farm having a plurality of milking positions for milking animals distributed in one of at least a first group of animals and a second group of animals, a milk passageway arranged to transport milk from the plurality of milking positions towards a milk storage tank, and a milk analysis device configured to obtain a value of a measured biomarker or a constituent in milk for each of a plurality of milk samples, the arrangement being configured to:

• obtain an animal identity of a respective animal individual being milked at a milking session from an animal identification system,
• obtain or generate at least one timestamp for a milking event of each animal individual being milked at the milking session,
• determine whether a respective animal individual being milked at the milking session belongs to the first group of animals,
• store a first timestamp corresponding to the first animal individual of the first group of animals being milked at the milking session,
• determine whether a respective animal individual being milked at the milking session is a first animal individual that belongs to the second group of animals, and, when the respective animal individual being milked at the milking session in the milking entity is the first animal individual of the second group of animals, store a second timestamp corresponding to the last animal individual of the first group of animals being milked at the milking session in the milking entity,
• obtain or generate a milk sample timestamp for each milk sample of the plurality of milk samples,
• obtain the value of the measured biomarker or the constituent in milk for each milk sample of the plurality of milk samples from the milk analysis device,
• assign a group score to the first group of animals based on the values of the measured biomarker or constituent for the milk samples with milk sample timestamps within a time period from the first timestamp to the second timestamp.
