The invention relates to a method to automatically predict a calving moment of a cow, comprising: recording, by a three-dimensional camera system, at least one three-dimensional image of the cow, processing, by a processing device, the at least one image of the cow, wherein processing of the image comprises determining a parameter indicative of the calving moment, and predicting a calving moment of the cow on the basis of the parameter.

Method and device to automatically detect calving

A method and a device for determining the emission of greenhouse gas, in particular methane, by ruminants, in particular dairy animals includes counting eructations ('belches') of the animal. This is done by measuring a signal linked to the eructations, for example sound with a microphone. Given that the methane content of an eructation of this type is more or less constant, the total methane emission can be derived therefrom by counting.

A method for monitoring oestrus of a cattle animal, for example a cow. The method includes: a) collecting activity data of the animal, b) computing a current activity level based on the activity data, c) deciding whether to generate an oestrus attention signal by comparing at least one current activity level to a corresponding baseline activity level. The computing b) further includes b1) detecting travelling movements of the animal and b2) correcting the baseline activity level for detected travelling movements.

Monitoring activity of an animal in a system for housing freely moving animals including a plurality of animal ID stations, includes the steps of a) recording a first visit of said animal at a first of said animal ID stations, b) recording a subsequent second visit of said animal at a second of said animal ID stations, and c) determining a distance covered by said animal as the distance between said first animal ID station at said first visit and said second animal ID station at said second visit. With such simple means, parts of which are already present in e.g. most robot dairy stables, important information about activity of animals can easily be gathered.

System and method for automatically determining animal position and animal activity

A method to determine a body condition score of an animal including: providing a three-dimensional camera system configured and arranged to record at least one three-dimensional image of the animal, and an image processing device to process the image; recording at least one three-dimensional image of the animal; processing the image. The processing the image includes: forming a three-dimensional surface representation of a part of the animal from the three-dimensional image recorded by the three-dimensional camera system; determining, in the image, reference points of the animal, at least including hook bone points and pin bone points of the animal; selecting a surface part of the animal representative for a body condition of the animal using the reference points; analyzing a first parameter representative for a body condition of the animal of the selected surface part; and determining the body condition score based on the first parameter.

A method and device are provided for generating an attention indication for a dairy animal that is kept in an environment with a freely accessible robotic milking system, including measuring a plurality of visit intervals, milking intervals, respectively of said dairy animal, determining a value of a statistical parameter regarding the measured plurality of intervals from the measured intervals, generating the attention indication, in particular a mastitis alarm signal, if the value exceeds a predetermined threshold value. Valuable information can be derived from the spread of, or change in, the values.

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: 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.

The invention provides a method and device for generating an attention indication for a dairy animal that is kept in an environment with a freely accessible robotic milking system, including measuring a plurality of visit intervals, milking intervals, respectively of said dairy animal, determining a value of a statistical parameter regarding the measured plurality of intervals from the measured intervals, generating the attention indication, in particular a mastitis alarm signal, if the value exceeds a predetermined threshold value. Precious information can be derived from the spread of or change in the values.

The invention provides a device and method for milking a dairy animal, comprising at least two sensors for measuring milking parameters. Usually, an alarm is generated if a specific number of parameters each are outside a given range. According to the invention, now an alarm is also generated if said specific number of exceedings is not achieved, but if another, and usually greater, number of parameters each are within a larger, more flexible, range. As a result thereof, the actual alarm parameters with 'hard' limits can be selected, in order that false-positive messages are prevented to a considerable extent. In the grey area of almost exceeding, an alarm can still be generated if sufficient parameters are in dubious areas.

Device, method and computer program product for milking animals

A system and method for managing an agricultural device, including connecting the agricultural device to a network, collecting operational data relating to the agricultural device, granting an access right in respect of the collected operational data to an entity connected to the network, receiving data from the entity in response to the access right, and managing the agricultural device on the basis of the collected operational data and the data from the entity. The method may be implemented for managing multiple agricultural devices, and may be implemented in a computer readable medium. In one embodiment, the operational data relates to clinical mastitis detection.

Method of and computer program for managing one or more agricultural devices

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.
