I have often found that if I see blood then I am usually dealing with coccidiosis and a couple of doses of corid will do the trick. Again, it goes directly to the gut tract. If it is viral, I don't know of any way to really treat it except for supportive with electrolytes and all to keep it from getting weak. I think that there has been some use of anti-biotics, but don't know if they only help to prevent a secondary bacterial infection. There is a vaccination that can be given to a cow pre-calving for the rota and corona viruses, and I believe there is something you can give to day old calves also. I usually have the coccidia and occasionally an e-coli to deal with.
We used to vaccinate the pregnant cows with Scour Bos 9 prior to calving but we now give each calf a First Defense bolus, preferably within 12 hours and rarely have scours (or at least nothing that warrants treatment).
