## What is Byrelog?

Byrelog is the daily work sheet for the dairy herd: on the phone, in the barn, with or without signal.

WORK LISTS THAT KEEP THEMSELVES
Expected calvings, dry-offs, pregnancy checks, open cows, open heifers and cows whose milk has dropped, worked out from your own registrations and your milking system, with the days and thresholds you set. One tap opens the cow card.

THE COW CARD
Everything about one animal: calvings, inseminations, pregnancy checks, dry-off, yield over the last 7 and 30 days, the last day against the last 48 hours, and the whole history.

REGISTER ON THE SPOT
Calving, insemination, pregnancy check, dry-off, registered in the barn and sent when the phone has a connection again. Nothing is lost.

YOUR OWN LISTS
Hoof list, watch list, "check on these": make the lists yourself, put animals on them, tick them done.

DATA FROM THE MILKING SYSTEM
Milkings, calvings, inseminations and pregnancy checks come from DeLaval DelPro, Lely and ALPRO through a small program on the farm PC. Yield per cow, and hot and cool days set against the milk.

ASK THE HERD
"How many cows calve in the next 10 days?" "Show all heifers." "Which cows have dropped in milk?" The answer comes as a figure, a table or a chart, computed on the server from your data, never guessed. Save it as a report that runs again with today's numbers.

THE ADVISER
Ask about thresholds, key figures and recommendations. The adviser answers from a knowledge base of read sources, names the source, and sets your herd's own figure beside it. The vet still decides.

SEVERAL USERS PER HERD
Owner, staff, vet and adviser can work in the same herd, each with their own role.

Byrelog is made in Denmark for dairy farmers in Denmark, the Netherlands and Germany. The app is in Danish, English, Dutch and German.
