I would assume that you worked with your vet to diagnose your problem? He knows your herd better than anybody. You should have a sensitivity from the lab to see what antibiotics may work? If the herd is well vaccinated for clostridium, then go with histophilus vaccine by itself-like Somubac. Should be less stressful. Consider running ctc in the diet also.
