I lost a calf once to bloat, so I hope that yours makes it okay. I keep some bloat medicine from my local animal supply store in hand just in case. But if caught early, some extra straw like hay can help.
I just had one of my hereford heifers give me a scare. We thought that she was dead or dying from bloat. But it turns out that she likes to lay on her back with her feet in the air. (Totally freaked me out, then she got up and was chewing her cud. It's like she was laughing at us.)
