Abstract: This document relates to a method for determining in a young animal a phase transition from a first development phase to a second development phase. The method comprises measuring, with a measuring instrument, one or more body or behavior parameters of the animal during a period of time and producing one or more measuring values for the or each measured body or behavior parameter. The one or more measuring values are received by a controller with which the phase transition is detected on the basis of the measuring values. The step of detecting the phase transition comprises processing the measuring values and, depending thereon, determining an extent of the animal's attention to solid food. Further, the document relates to the training of a self-learning data processing model, and to a livestock management system.

Abstract: A tag for attachment to an animal comprising: a transmitter unit for generating a transmitter signal; a first antenna unit connected with the transmitter unit, for emitting the transmitter signal; an energy source for providing electrical energy to at least the transmitter unit; and a housing in which the transmitter unit, antenna unit and the energy source are included, the housing being provided with an attachment opening for receiving therethrough an attachment element for attachment of the tag to the animal, characterized in that the first antenna unit is provided with at least one first winding which extends around the attachment opening.

Abstract: Measuring device for measuring physiological data of an animal such as a mammal for determining at least one condition parameter of the animal, comprising a first and second module (12,14) which are configured to be worn, in use, by the animal, wherein the first and second module are furthermore configured for them, from a condition of being mechanically separated from each other, to be mechanically connected with each other whereby in the connected condition, in use, between the first and second module is a skin part of the animal, wherein one of the modules comprises a source (122) for emitting electromagnetic radiation such as light (L) and wherein another one of the modules comprises a sensor system (142) for measuring a parameter such as intensity of a fraction (Lm) of the emitted radiation (L) received via that skin part and for generating a measuring signal (SL) which is indicative of the measured parameter, wherein the measuring device is configured such that, in use, the first and second module can p

Abstract: Method and systems for monitoring the growth of animals, comprising: a. bringing together animals in at least one space where they can freely move; b. obtaining a 3D image of an area within the at least one space with at least one 3D camera and/or a multiplicity of 2D cameras; c. supplying 3D information of the space to a signal processing unit; d. with a first predetermined algorithm, recognizing an animal in the 3D image; e. determining the identity of the animal; f. with the signal processing unit, according to a second predetermined algorithm, estimating a growth parameter of the animal recognized in step d.; g. repeating steps d.-f. when the animal appears in the image again; h. with the aid of computer collecting the information obtained in steps d.-g. to obtain insight into the growth of the animal over time.
