Bolus for feeder cattle – without the GPS transmitter


Cattle, like other ruminants, have four stomachs. The special structure of the cattle’s digestive system allows us to easily insert a small cylinder-shaped device, called a bolus, into the calf’s rumen.
The bolus remains inside the calf until it is slaughtered.
The commercial use of boluses has been expanding over the last decade, leading to a huge revolution in the field of monitoring and controlling cattle feedlots and barns.
Beyond the identification sensor in the bolus, (which, as mentioned, we use to record weight data) additional sensors are inserted into the bolus, which allow us to receive other important data related to the cattle and their condition.
* Temperature sensor
* pH level in the stomach
* Mobility sensor



● The farmers get on-line important data on feeder health, such as body
temperature and mobility inside the farm. In this way, the development
of diseases and other veterinary problems can be identified and treated
● From the pH sensor, the farmers get "inside information" about their
feeders, leading to a better understanding and adjustment of each
feeder’s diet, to improve feed efficiency and weight gain.
● The farmers get alerts in real time of any abnormal (or unwanted) reading.
