The cows teats are most likely plugged, get her in a chute and get the milk flowing. She also looks like she has edema which makes it hard for her to let her milk down. Once you get the teat plugs out, the calf bumping the udder will lessen the edema and the calf should be able to nurse. Don't stop feeding the calf till you know it is getting milk from the mom.
Calves shed the lining of their stomach shortly after birth and that along with the crap milk replacer is probably what is causing the bloody stool. As long as the calf is acting fine, don't go throwing a bunch of meds at it, they can do more harm than good.
