Animal Health: Automatic ID and Cow Temperature Monitoring

Our tiny passive RFID Temperature Sensor IC enables automatic daily temperature recording and permanent tamper-free animal identification for livestock. As dairy operations get bigger and bigger, it's more crucial than ever to quickly and accurately detect sick animals. Our Wireless Temperature Sensor IC is embedded in our specially-designed rumen bolus and requires no batteries. It resides permanently inside the cow and automatically measures a cow's core temperature providing advance alerts of critical changes in temperatures which may allow early detection of sickness, estrus, heat stress, and the onset of calving. No wonder the cows are happy—no manual temperature checking is required—and it's designed to last for the animal's entire lifetime.

Phase IV's exclusive distributor of the cow bolus system is DVM Systems.

The Problem

The US dairy industry is consolidating rapidly. Fewer dairy operations are family operated and, as a result, the care and attention given to each dairy cow has been significantly reduced in larger, more automated dairies. Death rates and loss of production from sickness has climbed steadily in these larger operations.

The Solution

The Phase IV Dairy Cow Monitoring System, distributed by DVM Systems, automatically monitors each dairy cow’s temperature and ID as it enters the milking parlor, two to three times per day. As a result, the dairy operator receives a 24 to 48 hour advance notice on illnesses and outbreaks before visual signs appear, reducing treatment costs and mortality rates.The Phase IV Dairy Monitoring System consists of:

a bolus, equipped with a passive RFID chip (Phase IV's SensIC™) and an integrated temperature sensor (no battery)
and a Dual Fixed Reader for collecting temperature data from the bolus.

The bolus is administered orally using a standard balling gun. Once ingested, the bolus settles into the dairy cow’s reticulum (one of the stomachs). The density of the bolus keeps it from passing through the digestive system.
Dual Fixed Reader Panel
The bolus is read by a Dual Fixed Reader (DFR). The DFR consists of two panels mounted at the entry to the milking parlor. As cows pass the Reader, a magnetic field induces a small electrical charge inside the bolus, sufficient to energize the transmitter. The bolus responds to this interrogation signal by transmitting its globally unique identification number and temperature on a coded radio-frequency. Alarms for high-temperature readings can be triggered, enabling early detection and immediate action. Once the DFR collects the information, the information is sent via Ethernet or Wi-Fi to user or third party application.

The Benefits

The rumen bolus does not use batteries and is encapsulated in FDA and USDA approved materials. It, therefore, provides tamper-proof identification tracking and temperature sensing for the entire lifespan of the animal.

Alarms for high-temperature readings can be triggered, enabling early detection and immediate action.

Once the DFR collects the information, the information is sent via Ethernet or Wi-Fi to user or third party application. This application mines this data to identify livestock that are potentially ill and permits the early intervention in health management. In summary, the system
