What was given, in what dose, who administered it, and from which day milk or meat may leave the farm.
It starts with something seen in the shed: a cow eating less, limping, with a swollen udder. The observation is written on the animal's record, and if it turns out to be real, a medical case opens from it and holds together every step that follows.
That way you are not left with five loose treatments on the same record, with nobody able to say which belonged to what. The case gathers them and closes them when the animal has recovered.
Where they apply, the platform keeps the two periods separate: the one for milk and the one for meat. They are not the same thing and, for the same medicine, they almost never end on the same day.
When you open the application you see which animals are under an active withdrawal, which one covers milk only, which covers meat only, and for which both apply. When none is active, it says so plainly: the whole herd can be sold from and delivered from.
Vaccinations and procedures are recorded the same way, with the date and the person who carried them out, and the next dose in the schedule can be planned on the spot. When you open the platform, the ones due today and the overdue ones are waiting.
The veterinarian can be added to the farm team, with access only to what he needs. What he writes stays signed with his name and the farm's clock, and you see in the history who wrote what.
Record the treatments once, and the platform tells you from which day milk and meat may leave the farm.
