  • Patent number: 9320256
    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.

  • Patent number: 9250226
    Abstract: A method for estimating a greenhouse gas emission from a ruminant in a loose housing environment, and in a predetermined time period from T0 to Tdesired, the method including: determining a model emission rate function EM(t) for the ruminant determining the moments of eating feed by the ruminant, at least during the predetermined time period, as a series of points in time {T1, T2, T3, . . . , Tn} constructing the estimated real emission rate function ER(t) on the basis of the model emission rate function and the moments of eating feed, and integrating ER(t) from T0 to Tdesired. Also provided is a greenhouse gas emission estimation device, arranged to perform this method. In the device and method, use is made of the insight that knowing the eating moments can fine-tune calculations for establishing greenhouse gas emissions from the animals.

  • Patent number: 8567344
    Abstract: The invention provides a milking device having at least one teat cup connectable to a teat of a dairy animal, and a method of controlling the milking device. A measuring sensor measures the amount of milk secreted. Data regarding the dairy animal are collected in a control unit. The method includes the steps of: providing a milking frequency determined in a first manner at a first lactation phase and a milking frequency determined in a second, different manner at a later, second lactation phase, for example, the stimulation phase and the stable phase, respectively, wherein the first manner results in a higher milking frequency than the second manner in the same circumstances; identifying a dairy animal and determining the associated milking frequency; milking the dairy animal dependent on the milking frequency; determining the milk production; and switching from the first to the second lactation phase, dependent on the milk production.

  • Patent number: 8397673
    Abstract: Method of supplying feed to animals with the aid of a group of feed stations which are accessible to those animals, wherein the feed stations, following the identification of an animal, supply feed to that animal according to a feed program for that animal adjusted to that individual animal and taking into account data relating to earlier feed supplies to that animal, wherein data relating to a feed supply to an animal are made available to each feed station via data connections, and wherein, in the event of failure of the data connection for at least one of the feed stations, at least one of the feed stations is operated to switch over to a safety feed program to reduce the feed supply to an animal identified at that feed station.
