We have a few cows with diarrhea after calving and some frothing of the mouth. The hay we are feeding does have some clover in it but not enough, IMO, to cause a problem. Unfortuneately, this is the last hay I have, so I don't have any thing else to mix or feed. As long as we watch for bloat, is there any other things to be watching and are we OK to continue? Anything we could supplement to help the diarrhea?
