Kathy can you please send me a link to this chart? I want to save itIt's a completely different type of drug.Both are good for some things, but not good for others.I've got corid and probios now. Looking at Terramycin opthamalic ointment- is the oxytetracycline hydrochloride better than the bacitracin (and other two?) in triple antibiotic ointment? Is terra-vet 200 (oxytetracycline 200mg/ml) a better broad-use antibiotic than tylan?Not worms or coccidia. He recommended probios, so I'm at TSC. What else should I get while I'm here? I only have tylan at home.-Kathy
