Devices, systems, and methods for detecting estrus in subjects are provided. Devices include a housing configured for intravaginal/intrauterine deployment and retention and a sensor disposed in or on the housing, and are configured to use condition information sensed by the sensor to determine an estrus condition of the subject. Methods include deploying a device in the subject, sensing the condition information, and determining an estrus condition using the condition information. Systems include a device configured to communicate with a base station and/or with other implanted devices, which are located within a reception radius thereof, regarding the determined estrus condition.

An animal condition indication assembly includes a panel with a plurality of layers. The panel includes a first edge, a second edge, a first lateral edge and a second lateral edge. The layers include an adhesive to be attached to a first animal. A substrate has an upper surface and a lower surface and the adhesive is positioned on the lower surface to adhesively secure the substrate to a rump of the first animal. An intermediate layer is positioned on the upper surface and includes a first color permanently affixed to the substrate. The first color is UV fluorescent. A flood coat is removably positioned on and covers the intermediate layer. Portions of the flood coat are removed by a second animal upon mounting of the first animal by the second animal. The flood coat is opaque and has a different color than the intermediate layer.

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.

Apparatus for managing animals such as but not limited to livestock. In some embodiments, a tag assembly is configured for attachment to an outer ear of an animal. The tag assembly has a main body and a shaft that extends through an aperture extending through the outer ear to attach the main body to a facing surface of the outer ear. A primary temperature sensor of the tag assembly is configured to obtain outer ear temperature data indicative of an outer ear temperature of the outer ear. A control circuit is configured to receive the outer ear temperature data via a wireless communication link with the tag assembly. The control circuit determines a health state of the animal in response to a localized change in a magnitude of the outer ear temperature data in relation to a set of ambient temperature data over a selected time interval.

A milk analyser system is provided for detecting the presence of a biomarker, the system comprising: a colorimetric sensor which is arranged to change colour in the presence of a biomarker to be detected; and an optically transparent container which contains the sensor, the container being openable in use to allow milk received by the system to pass over the sensor in order to provide an indication of the biomarker in the milk, any change in colour in the sensor being detectable by viewing the sensor through the container.

This invention relates to a method for monitoring estrus and ovulation, and for determining time for insemination of an animal, preferably a pig. The present invention furthermore relates to a system for monitoring estrus and ovulation, and for determining time for insemination of an animal, preferably a pig.

Provided is a livestock biometric information scanning system and a control method thereof. The livestock biometric information scanning system includes a rail installed at a certain height from a floor of a livestock barn across a plurality of breeding spaces, a sensor unit installed to be movable along the rail and configured to obtain images and/or body temperatures of livestock located in the breeding spaces, a wire connected to the sensor unit, a driving unit configured to pull the wire, and a control unit configured to control movement of the sensor unit so that the sensor unit is located above any one of the plurality of breeding spaces through the driving unit.

Apparatus and method for managing animals such as but not limited to livestock. In some embodiments, an ear tag assembly has a main body, a backing member and a shaft that extends through an aperture through an outer ear of an animal to interconnect the main body and the backing member. A primary temperature sensor obtains an outer ear temperature of the outer ear. An ambient temperature sensor obtains an ambient temperature of a surrounding environment external to the animal. A control circuit receives the outer ear and ambient temperatures and determines a state of the animal responsive to a comparison of the outer ear temperature and the ambient temperature over a selected time interval.

A disease management method and apparatuses performing the disease management method are disclosed. The disease management method may include receiving bioinformation of a cow from a biosensor capsule provided in a stomach of the cow, determining a health state of the cow by analyzing the received bioinformation, and transmitting information associated with the determined health state to a user who manages the cow, in which the health state may include at least one of a breeding-related state associated with estrus and delivery of the cow, a disease state of the cow, a methane gas generation state of the cow, or a rumen activity state of the cow.
