Abstract: Method of managing dairy animals in a free housing including a voluntary automatic milking system, and including determining TLM as the time since the last milking of an animal, determining AVMF as an average daily voluntary milking frequency for the animal, setting a desired milking interval DMI for the animal, marking the animal for manual collection if TLM and/or DMI fulfill a collecting criterion, making a list of marked animals, collecting and milking the marked animals, wherein the collecting criterion is fulfilled if TLM is above a first interval threshold, or if TLM is at least equal to the value of a mathematical function applied to the DMI, or if AVMF is below a frequency threshold, and TLM is above a second, shorter interval threshold MRI. Also a milking arrangement is disclosed with a milking robot having a control device arranged to perform the method.

Abstract: A method and system for managing a group of dairy animals in which a subgroup of dairy animals to be separated from the group of dairy animals is determined. A planned collection time is determined, at which time it is planned that the dairy animals in the subgroup of dairy animals to be separated are separated from the group of dairy animals. An individual separation period, which is determined by the length of time from a start time, preceding the planned collection time, to the planned collection time, is selected separately, for each individual dairy animal in the subgroup of dairy animals to be separated, in dependence of a property of said individual dairy animal. Each individual dairy animal in the subgroup of dairy animals to be separated is separated from the group of dairy animals during the individual separation period selected for said dairy animal.
