We were getting cows up to work once and the best calf in the bunch starting acting strange and just died. Had vet out and was blackleg. I had one die once with it and was on the other side of a 5 strand high tensile fence. He musht have had a seizure or out of its head as it died. It was blackleg too. I started vacc. at birth with alpha 7 MB and then again at weaning.
