Name of person giving the medicine/remedy or the name of the prescribing vet. Date of end of withdrawal period. A common mistake is entering the number of withdrawal days instead of the date of the end of the withdrawal period. Where an individual animal is treated, the identity of the animal must be clearly documented, for example using the tag number or freeze brand. Where the remedy is administered to a group of animals, it must be possible to clearly identify each animal in the group from the relevant herd register (eg all calves born from 1 January to 31 March only, or “all replacement weanling heifers”).
