Birth, arrival, departure, death and slaughter go out over the official interface of the Tierverkehrsdatenbank — wherever the interface permits it. What comes back is the TVD's confirmation number, time-stamped, in your animal's record.
No credit card. Your real herd, every module. You send your own TVD notifications from your first subscription.
You record the event once: lambing, arrival, departure. Herdy checks the details before anything goes out.
Herdy is an accredited interface partner and sends your notification over the official TVD interface — signed in with your own Agate login.
The Tierverkehrsdatenbank processes the notification and sends back a confirmation number. It then sits with the animal — with the date and the time.
Agate stays what it is: the federal portal. Herdy does not replace it — Herdy is the way there, without you typing the note from the barn a second time.
A notification is a declaration to an authority. That is why, in Herdy, a fair amount sits between your tap and the interface.

Not everything Herdy can do is permitted by the TVD interface for every species. Here is what works today — and what does not.
| Notification | Cattle | Sheep | Goat | Pig |
|---|---|---|---|---|
| Birth | Yes | Yes | Yes | No individual-animal notification in Switzerland |
| Arrival | Yes | Yes | No — deactivated by the TVD, runs through the portal | As a group or holding notification |
| Departure | Yes | Yes | Yes | No |
| Death | Yes | Yes | Yes | No |
| Slaughter | Only by the slaughterhouse | Yes | Yes | No |
| Sömmerung as a collective notification | Yes | Yes | Yes | No |
| Cancel a notification | Yes | No — not possible on the TVD side | No — not possible on the TVD side | No |
| Fetch the herd from the TVD | Yes | Yes | Yes | No |
You sign in with your existing Agate login. Herdy stores no password of yours. For security reasons the connection expires after a short time and is confirmed again next time.
Your herd is already in the TVD. Herdy fetches it, with ear-tag numbers, sex and dates of birth. You type nothing.
Lambing, arrival, departure — where it happens, on your phone.
The notification goes out, the TVD's confirmation number comes back and stays with the animal.
The same entry also produces:
Births must be reported within 30 days; arrivals, departures and deaths within 3 working days. For every open event Herdy shows how much time is left, and sends you an email before it gets tight.

Seven days free, no credit card. Your real operation, your real herd — and a real confirmation number from the TVD.
