Medicine before slaughter

Hello, Can you inform me on the rules regarding medicine’s to livestock before slaughter. In particular variations and the number of days before slaughter I should stop.
Thank you.

There is only one rule regarding medicine and livestock before slaughter which is:  any animal that is intended for slaughter, the medicine withdraw period which is clearly  instructed with the product, must be respected . Slaughtering an animal during the medication period makes the carcass and offal of that animal UNFIT for human consumption.  Unfortunately, there is no fixed rule and withdrawal period varies from species to species and medicine to medicine. The only suggestion is that if you intend to slaughter the animal you should bring that  to the attention of your own vet  who is treating the animal,  then he/she is able to take a more informed decision based on the welfare of the animal and your profit.
