Found a cow dead yesterday. She is very bloated, the skin seems loose from the muscle. Black splotches apear on her underbelly. I plan to have a vet come out and check her out, but I was wondering what it could be. Blackleg??I didn't think blackleg affected older cows. No grass here yet, so can't be bloat. She is probably over 5 years old. Planned to calve mid-May. No symptoms of anything except black splotches.
