I just brought my steer home from my breeder at 3 months old and 275 pounds last week. He refused to eat the Lyssey and Eckel grower and calf mana we started him on, so we switched him over to a creep feed similar to the one he received before we took him. He still barely touches the feed or the hay in his pen. We already gave him B Complex and B12 a few days later hoping to boost his appetite. Still no change, except he now has diarrhea. Any suggestions on how I can get some feed into his mouth?
