Field-tested and working in farmers' hands.

On a farm, the costliest thing is noticing too late.

No herdsman can watch every cow around the clock. By the time a fever is visible, milk loss has already begun — and a missed heat means another lost cycle.

01

Disease spotted too late

By the time fever, digestive or metabolic problems are visible, milk and animal losses have already started.

02

Missed heats

Miss the insemination window and the calving interval gets longer. Every missed cycle is lost income.

03

Calving and labour

Night checks, staff shortages and growing herds. Knowing calving is coming protects both cow and calf.

From bolus to phone — alerts hours earlier.

Each cow is identified by her ear tag number, and the bolus is paired with it. Data travels from the barn to your phone, and from there to your vet.

Many farms, one dashboard for the vet.

Veterinarians join at the farm owner's invitation and only see the farms they are invited to. Urgent cases appear in one list, with bolus data ready for the examination record.

Ask a question
What is a rumen bolus?

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.

Does the bolus harm the animal?

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.

How long does the bolus last?

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

Which animals is Edell Biosense for?

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.

What does Edell Biosense detect?

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.

How does it detect heat?

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.

Our farm has a weak internet connection. Will it work?

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

When do the alerts start?

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

What happens to the bolus when an animal goes to slaughter?

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

Who owns the data?

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.

What happens if something breaks down?

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.

Which countries do you serve?

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.

How much does it cost?

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.

Can the rumen bolus be given to heifers?

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.

Does the bolus affect milk yield or meat quality?

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

How do alerts reach my phone?

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

What should I do when I get an 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.

What herd sizes is it suitable for?

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

Does the system also monitor heat stress?

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.

Let's plan a free assessment for your farm.

Tell us your herd size and country, and we'll come back to you with a quote and installation plan.
