This AM, we found one of our show heifers dead (she was 14 month old). We saw her as late as 9:00PM last evening, at which time she showed no sign of illness or stress. In fact, she was at the trough eating hay when we last saw her. At 5:00AM she was cold and stiff. No signs of bloat, foaming at the mouth or struggle. Rations consisted of free choice hay, 12% show mix and beet pulp. She had access to Vigertone 32 SMG free choice minerals. The other heifers in her pen seem OK. Any ideas??? Could she possibly have been pushed too much?
