If you can call a vet preferably. We have had to like that this spring that couldnt stand up without us holding them up and our vet told us to do this and it was amazing the turn around on these calves from acting like they wouldnt make it through the night and an hour or two later they could stand up and walk on there own. What we gave was Baytril, Vitamin B complex, Banamine, and Lifeline, which is a colostrum supplement.
