I live in La, Went to lower Mississippi this morn (Amite Co). Fellow there said his neighbor just lost 2 calves from blackleg? And a third sick? How do cows get this and when do you need to vac. for it? If I was to walk in a feild with said dead cows - would i be a carrier to other cows? (NO i didnt go to feild just trying to understand transmitters) Also if this is such a long standing and horriable sickness -- Why on earth were the dead ones left on the ground to rot? How do cows/calves get it? thanks to all
