Hello! I'm new to the forum and to raising cattle. My 15 year old son is working on a dairy farm and recently brought home a set of bull/heifer twins (now 4 weeks old). The bull has had a bit of a rough time with things. We got him through some sort of illness and a case of scours, followed by hair loss on his backside. He was doing well when we noticed a lump on his lower jaw a couple days ago. After consulting with the farmer my son works for and a couple of others, we were advised that it was either an infected tooth or abscess from a cut in his mouth and to give him 5 mL penicillin, two doses the first day, then one dose a day for a few more days. I picked up the penicillin last night but the label said to give 1 mL per 100 lbs body weight so 5 mL seemed way too high and we only gave 0.8 mL. I have since read that many vets recommend 10 mL per 100 lbs body weight so I guess 5 mL would be ok afterall. Anyway, immediately upon giving him the penicillin in his hindquarters, we began wheezing and coughing and lost coordination in his back legs. Within 10-15 minutes, he seemed to be ok and looked good this morning but I am reluctant to give him a second dose in case it was an allergic reaction. Should we proceed with giving him another dose of penicillin or switch to a different antibiotic? Go ahead and increase the dose to 5 mL?
