The vets have prescribed me a 4-day course of Synulox injections and a shot of metacam for one gimmer who's come back from her trip away to the tup lame with a swollen, hot knee. I understand they can do this under the prescribing cascade (neither is specifically licensed for use in sheep), but what do I put down in my medicine book for the withdrawal period? The NOAH website gives the information for cows and pigs, I'm guessing that the period for pigs is going to be closest, so should I use that?
