A rumen bolus is a small sensor that a veterinarian gives to a cow by mouth. It stays in the reticulo-rumen and continuously monitors the cow's body temperature, activity and drinking behaviour. The Edell Biosense bolus sends this data to the mobile app, so fever, heat and upcoming calving are flagged hours in advance.

No. The bolus is given orally by a veterinarian and stays in the cow's rumen. It is animal-safe and does not affect the cow's daily life or milk yield.

The bolus lasts 3 years. The app shows the status of every bolus at all times.

It is used in dairy and beef cattle, in cows and heifers. It works at every scale, from small family farms to operations with thousands of head.

It detects fever, heat, upcoming calving, inactivity and changes in drinking. Every alert arrives on the phone with a chart, and the farm owner, herdsman and veterinarian all see the same alert.

Cows become noticeably more active when they are in heat. The system learns each cow's normal activity pattern, picks up this increase and sends an alert when the insemination window is approaching. Heats that start at night and would otherwise be missed are caught too.

Yes. The boluses connect to the barn receiver without needing the internet, and the app is designed to work on weak connections.

Monitoring starts straight after installation. In the first days the system learns each cow's own normal, and alerts become increasingly accurate.

The bolus is recovered at slaughter and the animal's record is closed in the app.

The data belongs to the farm. A veterinarian only sees the farms they are invited to, and the farm owner can withdraw the invitation at any time.

You can reach us via the app, our WhatsApp line or an automatic system alert. We usually solve problems remotely; if needed, our team comes to your farm.

We are based in Istanbul, Türkiye. Farms and distributors outside Türkiye can message us on WhatsApp with their country and herd size, and we will get back to you with the right set-up.

The price depends on the number of animals and the needs of your operation. After a free assessment, we prepare a quote tailored to your farm.

The bolus must be given to animals of a suitable age and weight. Which animals receive it is decided together with the veterinarian during the farm assessment.

No. The bolus stays in the rumen and does not affect the cow’s feeding, rumination or yield. It is recovered at slaughter.

Alerts arrive in the mobile app as instant push notifications. The farm owner, herdsman and invited veterinarian all see the same alert.

The alert screen shows the reason together with a graph. Check the animal; if you suspect fever or illness, reach your veterinarian with a single tap. Treatment decisions are always made by the veterinarian.

It can be used on farms of every size, from small family farms to operations with thousands of head.

The bolus shows rises in the cow’s body temperature. For farms that also want to monitor barn temperature and humidity, we are developing Edell Climate environmental sensors.
