Orphan calves can be saved, the key is colostrum in the first 12 hours of life.

Q&A:
We had a calf born that could not find the udder to nurse. I milked the mom and got her colostrum into the calf. I gave the calf a small amount of supplement milk for a couple of days, hoping it would start to nurse but it never did.
