Cattle (Beef/Dairy)

Clinical context for cattle dosing

Cattle pharmacotherapy must respect withdrawal periods — meat and milk withdrawal times (where available from FDA, EMA, or FARAD) are the practical limit on extra-label drug use. Bovine respiratory disease (BRD) is the single largest indication and drives the macrolide / fluoroquinolone / florfenicol triumvirate. Mastitis pharmacotherapy is governed by intramammary product registration and milk-residue rules. Extra-label drug use in food animals is restricted by AMDUCA in the US; verify withdrawal data before treating.
