I work with Calves from birth to freshening and MOST of the bloat cases I see in my area are from Clostridium. I believe types C & D are most previlent. When we have a calf that is bloated I give 10CC pennicillin orally IMMEDIATELY when I see they are bloated, or even if their stomach just looks extended slightly. It usuallly takes the bloat off very quickly because it kills the Clostridium bacteria in the gut. It also kills the good bacteria in the gut too, but this is minor given the alternative (death). If clostridium bloat isnt caught right away a calf can be completely healthy running around drinking milk and 3 hours later be deader than dead. We had one like this the other day. She drank milk at Noon, by 3pm she was dead.Cricket said:We're looking for your info/cures on bloat for the Emergencies, Injuries and Cures Index. Thanks!
