Friday at 5 pm we found a first time heifer down with a hiplocked dead calf, we got the calf out but the heifer has not been able to get up. Saturday morning at 8:30 we gave her a steroid shot that we got from vet, so far she has not seemed to improve, except she is eating grain good. We have lifted her several times a day, one back leg goes out to the side. Is their any hope for her?? How many days before we give up hope?
