When a cow is on treatment with any veterinarian drug there is usually a withhold period.

They will all have a veterinarian label stating the dose rate and withhold period. Note there is a different withhold period for milk and meat.

Identify the cow with paint so everyone knows the milk from this cow can't go into the vat. Every farm will have a standard protocol around how this is done. RED usually means "on treatment" and "withhold milk".

Some farms simply record cows on a whiteboard initially.

If you have a farm computer or operating system either record the cow here if you have been taught or make sure your manager is informed to.
making sure everyone on the team is fully understood the farm protocols around animal treatments and recording is critical to achieve good animal health outcomes and safe milk.
