Definitions
- the present invention relates to an arrangement, a bolus, a tag, and a method for monitoring the physiological state of an animal for determining the state of health and providing information for optimizing livestock management.
- Document CA2820857 refers to an apparatus for controlling a milking animal during milking of the animal.
- the apparatus includes a series of productivity sensors, each of which measures at least one indicator of animal productivity.
- Various temperature sensors which include at least two thermographic cameras, measure the heat output from different processing areas of the milking animal.
- a processor receives the heat outputs and productivity indicators, and uses a combination of these to determine the condition of the milking animal. The condition is indicated in real time on the monitoring device.
- Another sensor described in this document is an electrical conductivity sensor to measure the milk conductivity in the udder.
- Figure 3 illustrates a possible data view that includes three trend lines for electrical conductivity, udder temperature, and performance over time for data obtained for an individual animal.
- the cited document does not anticipate the technique of the present invention because in the document the measured media is milk instead of intraruminal saliva, the place of measurement is the udder instead of the stomach, the variation in conductivity is due to the contribution of salts due to cellular breakdown in the milk instead of the generation of saliva in the stomach and the result is to detect a possible infection of the udder instead of an ingestion of the animal.
- the drawback of the method of the cited document is that only the animal's milk productivity can be monitored, not other parameters of interest or diseases that are not associated with the cow's udder can de detected because it doesnot describe using a conductivity sensor inside de rumen and also fails to disclose that the conductivity measurement is carried out using alternate current.
- Document NL1008840 (C2) describes a dairy animal management system using sensors to allow the identification of individual cows and certain features such as milk temperature and conductivity to measure the animal's health. In addition, it uses an olfactory sensor to detect the level of acetone in the animal's breathing, so that the central computer can record the presence of a metabolic disorder that can occur in the stomach of a ruminant.

- the biosensor capsule includes a plurality of sensors, for example, an acceleration sensor, a gyro sensor, a temperature sensor, a methane sensor, and a potential hydrogen (PH) sensor, a battery, a weight, a communication module, and an antenna.
- the communication module and antenna can be used to communicate between the biosensor capsule and the disease management server.
- the biosensor capsule can transmit the bioinformation to the disease management server by accessing a communication network within a distance of 20 km through the communication module.
- the sensors can be integrated into a printed circuit board (PCB).
- the communication module and I or the antenna can also be integrated into the PCB.

- Possible rumen displacements and disorders are detected by means of a three-dimensional accelerometer by measuring the frequency of the rumen spasm.
- the device of the cited document is based on an electrolysis process using direct current that takes advantage of dissolved hydrogen ions as a change factor.
- the problem that appears is that it affects the medium and the measurement in itself (as clarified in the same document indicating that they can regulate the PH).
- this method uses the rumen as a battery, and according to its capacity to generate energy, it can calculate the PH. From what is described, it seems to be a more theoretical than practical development because it is very likely that salts form tartar around the electrodes, interfering with electrical conduction. Instead, the present invention uses alternating current and measures the concentration of salts (as electrolytes) in which the impedance or conductance of the medium is measured without affecting the media.

- the transceiver is preferably Microchip® brand model RN2903A
- the voltage regulator is preferably Texas Instruments® brand and model TPS78330DDCR
- the battery charger is preferably Microchip® brand, model MCP73831T-2ACI I OT
- the microcontroller is preferably Microchip® brand, model PIC16LF1825 and the IMU is preferably Bosh® brand, model BMI160
- Gateway 5 preferably consists of a standard LPWAN equipment (LORAWan, NBIoT, Sixfox, etc.) that relates the caravans with the Network Server to manage the network of devices and send the information to the cloud.
- LORAWan Long Term Evolution
- NBIoT Network Bidirectional Streaming Protocol
- Sixfox etc.
- Gateway 5 is in charge of managing the power and the transmission rate of the Caravans in order to ensure that hundreds of thousands can be communicated without losing information; on the other hand, they are in charge of uploading the collected information to the central servers.
- the Gateway 5 uses a high-speed link (point-to-point, 3G, 4G, 5G, Satellite, etc.) to send the collected data and receive from the Network Server the information necessary to manage [00062] Remote terminal
- One of the most notable aspects of the present invention is based on one or more remote terminals 32 with an application software (APP) that offers a functionality hitherto unknown in the art.
- the remote terminals 32 can be desktop PCs, portable PCs (Notebook or laptop type), Tablets or cell phones, which will communicate with the cloud software. This communication can even occur using LPWAN through a device that serves as an interface.
- the functions allowed by the use of the APP will be described in more detail below.
- the APP for tablet or mobile cell phone is used as an interface for the control and configuration of the caravans, showing the status of connection with them and the associated bowling pins, and if they are connected, it allows the user to choose the mode of use of the same ( continuous use or for periods).
- the APP application software is also used as a means of collecting usage data for further processing by the monitoring company in order to improve service and programs.
- the APP allows the configuration of livestock profiles that can be loaded and I or saved for use at another time and facilitate their identification.
- the APP application is downloaded to a cell phone or tablet and controls 100% of the caravans once they are turned on.
- the different measurement formats can be controlled I programmed from the APP: continuous use or by periods.
- Another function of the APP is that each animal can have its profile to be able to repeat measurements already made and to keep a record of the information of its possible health problems.
- Another function of the APP is to communicate to the different people on the team using the LPWAN network, the cellular network or WiFi.
- the APP keeps a record of the percentage of departure from some biological parameter.
- the APP software includes a crossstatistics function between animals to be able to share statistics and profiles.
- the present invention also comprises a method for monitoring the physiological status of an animal.
- the procedure consists of the following stages:
- the temperature will be considered normal according to the stabilization time, the outdoor ambient temperature, the conductivity in value and time, the interior and external activity of the cow. That is, first the intake of water and food will be discarded, which is not in a fermentation process, or in a specific activity (such as being in heat).More specific steps and parameters are explained in later paragraphs.
- Temperature is an indicator of the condition of common cattle that includes diseases such as metritis, mastitis, lameness and pneumonia.
- the water temperature (generally outside temperature)
- a simplified algorithm that the inventor has obtained is that, a decrease in temperature below 36 degrees Celsius in less than 4 minutes, added to a decrease in the same period of 15% of the conductivity, indicates an intake of liquid.
- the user may have information proportional to the volume of water consumed (this process can take between 20 minutes and an hour).
- Saliva contains bicarbonate (HCO3 -) and phosphate (HPO4 -) that give an alkaline pH to saliva (8.2 to 8.4) and that in the rumen act as a buffer against the production of acids.
- HCO3 - bicarbonate
- HPO4 - phosphate
