Get your free ticket Book a meetingByrelog brings in all the data your farm collects, from the milking robot to the health sensors. Ask a question about your herd and get the answer as a list, a table or a chart, counted from your own cows.
Free to join · Be the first to hear when we launch
Your milking robot, health and activity sensors, feed computer, weather station and barn climate control all collect data about your cows. But each technology keeps it in its own system, so one simple question can cost you an evening behind the computer.
My robot, my sensors and my own records all knew something about my cows. But getting one clear answer out of them meant hours behind the computer. I just wanted to ask a question and get the answer. That's why we built Byrelog.
The things you'd otherwise dig out of the robot software or keep in your head. Just type them or say them.

Calving, insemination, preg check, dry-off. Speak or write in English, Danish, Dutch or German. Saved on the phone, sent when there's signal.
Who's calving, who needs drying off, who's due for a check: the lists update themselves from what you record.
We launch Byrelog at EuroTier in Hannover, 10–13 November 2026, in hall 25 at stand K39. Join the waiting list and you'll hear first when you can start.
Byrelog started with a farmer's frustration: plenty of data, no clear answers. One of us is a dairy farmer, the other builds the software in Denmark.
Dairy farmer
Karst-Jan is a dairy farmer who loves innovation. His frustration was simple: the milking robot, the sensors and the registrations all collect data, but none of it came together by itself, and getting a clear answer meant hours behind the computer. He wanted to ask a question and just get the answer, from his own cows. That frustration is where Byrelog began.
Software · Byrelog
Denmark
Jesper has built software for dairy farms for years. In 2017 he co-founded Cowconnect, feed management for dairy farmers (now Feedlync), and led it for more than seven years. He knows what it takes to make IT tools that farmers actually use. At Byrelog he links all the different sources of data on the farm, so everything comes in by itself, and builds the assistant that counts instead of guessing.
Give every dairy farmer the answers already hidden in their own data, without turning farming into office work.
A farm where the robot, the sensors, the weather station, the feed computer, the partners and the farmer's own records work as one, and every question about the herd gets one clear, honest answer.
Every number comes from your herd, and you can see how it was counted.
Quick, simple, works without signal, and in your own language.
Tested in real barns, shaped by the people who milk the cows.
Byrelog Advanced is free for everyone until the end of 2026. After that you choose the plan that fits your farm, or stay on Byrelog Free for good.

Yes. Everything in Byrelog Advanced is included until 31 December 2026, for your whole herd, and we don't ask for a card. You only give your name, an email and your herd.
Right away. When you connect the farm PC, Byrelog reads the whole history from your robot, so you can ask about past calvings, inseminations and milk on the first day.
You choose. Carry on with Byrelog Advanced, switch to Byrelog Basis or Byrelog Excellent, or keep using Byrelog Free at no cost: registrations, the cow card and the standard lists. The price calculator above shows what each plan costs for your herd.
Yes, Byrelog Excellent: several herds in one account. Tell us about your situation and we'll help you set it up.
It can't make one up. Every figure is counted from your herd, and the answer shows what was counted. If a cow is missing from a list, she's missing from your records, and you'll see that on her card.
No. Your DeLaval or Lely software keeps running the robot like before. Byrelog only reads from it and puts your herd, and the answers, in your pocket. Nothing is written back.
Only the people you give access, per herd. Your vet or advisor can get a look-only view on every plan. With Advanced and Excellent, your employees can each get their own account, with only the data they need and their own dashboard. Your data isn't used to train anything and never leaves your account.
You keep recording. Everything is saved on the phone and sent when there's signal again. Your saved charts and the lists you opened stay available. Asking a new question needs a connection.
