A bovine estrus detection device includes a generally rectangular base having sides and ends, the base having a predetermined length and a predetermined width, and the width being less than the length, the base having a first side and. a second side. The first side of the base has a central region having a first color and end regions having a second color. The second color is different from the first color. An adhesive is disposed on the second side of the base for coupling the base to a female cow or heifer. A removable coating is disposed over the first side of the base. The removable coating is exposed for contact by male or female cows mounting the female cow or heifer to which the device is attached. The coating is adapted to being removed by mounting male or female cows, whereby the first and second colors become visible. Exposure of the first color in the central region is an. accurate predictor of activation and estrus.

System for determining a respective walked distance of animals in a barn during a predetermined time period. The system includes a Real-Time Location System, a database storing historical trajectories of the animals and a processing controller. The processing controller is configured to determine the walked distance of the animal by establishing a walked trajectory based on obtained data entities, and store the trajectory in the database associated with the animal; or detecting a gap of missing or incomplete data entities among the obtained data entities; and establish the trajectory by inserting replacement distance data in the gap, based on historical trajectories extracted from the database and store the established trajectory in the database.

An estrous sensor, which is implanted into a body of a domestic animal and detects estrus of the domestic animal, includes a first channel interface circuit, an output circuit, a temperature measurement circuit, and determination circuit determines whether the domestic animal is estrous based on the electrical conductivity of the body fluid of the domestic animal and the temperature within the body of the domestic animal.

Exemplary embodiments are directed to sensor apparatuses for attachment to an animal that include a housing and a sensor assembly. The housing can be attachable to the animal and includes an internal cavity formed therein. The sensor assembly can be disposed within the internal cavity of the housing. The sensor assembly includes a force sensor and an accelerometer arranged to detect force data and accelerometer data representative of a physiological state of the animal. Exemplary embodiments are also directed to method and sensor systems for detecting a physiological state of an animal.

Mounting behavior or the like by domestic animals or the like is easily detected. Included are a mounting-side apparatus attached to the neck of a first domestic animal and configured to emit a transmission signal, and a mounted-side apparatus attached at any position from the back to the tail of a second domestic animal. A communication interface of the mounted-side apparatus emits a response signal to a communication interface of the mounting-side apparatus.

A bovine monitoring system may include a rumination sensor, a motion sensor, a posture sensor. The rumination sensor may detect chewing by sensing jaw motion. The motion sensor may detect motion. The posture sensor may detect orientation of the bovine asset through detection of gravitational acceleration, detection of gyroscopic rotation, or a combination of gravitational acceleration and gyroscopic rotation. Using the recorded rumination, motion, and posture sensors, the bovine asset monitoring system may identify aberrations in the estrous cycle or physical or mental health of the bovine assets. A bovine monitoring system may include a thermal scanning device to detect localized heating of the vulva area of the bovine asset, which may be used to identify aberrations in the estrous cycle or physical or mental health of the bovine assets.

In one embodiment, the present invention provides an intrauterine device (IUD) comprising an oval shape, wherein the device comprises a core of magnetic material, an inert material or copper coating the core, wherein the coating comprises a pharmaceutical agent, copper or a combination thereof. Another embodiment provides a method to suppress estrus in a subject comprising inserting an intrauterine device (IUD) comprising an oval shape, wherein the device comprises a core of magnetic material and an inert material or copper coating the core.

An electronic monitoring device for attaching to an animal includes an NFC module facilitating wireless communication between a smart phone and the monitoring device, an accelerometer for monitoring acceleration of the head of the animal, and a microprocessor which determines various states of the animal from signals received from the accelerometer. The smart phone is programmed by a software application which allows an identifying code of the monitoring device to be read from the memory chip and cross-referenced in the smart phone with the identity of an animal, which can be inputted into the smart phone. Data relating to the states(s) of the animal can be read from the microprocessor through the NFC module into the smart phone. Additionally, data relating to the animal stored in a cloud server corresponding to the state or states of the animal is downloaded from the cloud server by the smart phone.

Mounting behavior is detected easily. A mounting behavior detection system includes a mounting-side apparatus, a mounted-side apparatus, and a charging apparatus. The mounting-side apparatus is attached to the neck or the chin of a first domestic animal, is configured to emit a transmission signal, and includes a battery. The mounted-side apparatus is attached at any position from the back to the tail of a second domestic animal and is configured to transmit a response signal in response to the transmission signal. The charging apparatus is configured to transmit power wirelessly to the battery.

The invention relates to a data network for automatically monitoring voluntary behaviors of individual animals of an animal herd. The individual animals of the animal herd each have a node of the data network. A further node is attached at a location which an animal preferably approaches in the course of a behavior to be monitored. In the event that the animal approaches the node, communication occurs between the nodes, in which communication one node is identified by the other node and a central data-processing system is informed that the two nodes have come into contact. The communication between the two nodes occurs by means of the transfer of electrical signals in a closed electrical alternating-current circuit, which also passes, among other things, through the body of the animal as an electrical conductor.
