Have got a lame ram which I initially treated with alymycin then after a no improvement penicillin. After several days with no improvement took down to vet who has prescribed 7 day course of Tylan, She said it was a deep joint infection and suggested if the tylan doesn't work he will probably have to have one of the cleats removed.There is swelling above the cleats but no infection broken through. Has anyone had this done? are they pretty much ruined and only fit for slaughter?
