Just got back from a national show in KC. While there one of my heifers just shut down. First two day everything normal, then see quite eating grain drinking water . She would eat a little hay and sip a little water. I tried appetite plus, Vita-ferm bolus nothing worked. I was worried if she could make the trip home, about 700 miles. Got her home 3 days later she started back. Any tips or tricks to keep calf's from going off feed at shows in the future.
