To anyone who wants an update: The calf is still off of the cow but he has actually gotten much sicker. No idea what he has because scours and/ or breathing hard are not among his symtoms. He had a fever, now it is normal but he is uncoordinated when walking. He always chews constantly as though chewing a cud but doesn't seem to eat enough solids to do so. He's had electrolytes, Vetsulid, Naxcell, selenium, B vitamins... The only thing we haven't tried is Corid for coccidiosis, but he doesn't have the symtoms for it. Since he doesn't have scours he is still on milk (tube-fed). Can't tell whether he is better or worse tonight.
If it were me, where the cow already has purchased a one-way ticket out (LOL), I'd separate cow and calf, take the calf up to the house and doctor him up there. Cow will be fine and will dry herself off. Calf will do better with more attention and a lot of TLC.
Calf now...if I remember the original post correctly, he's younger than 3 weeks and/or was younger than 3 weeks when symptoms showed up. That rules out coccidiosis.
Chewing is a good sign of pain. Have some banamine on hand? make him more comfortable - dose at 2cc/100lbs.
My vet commented to me once that some pathogens cause a lot of fluid loss ("severe" scours) and very little damage to the gut - hence the calf acts GOOD. I've had several calves get sick with scours where they'd guzzle a bottle down but have everything coming out the back end faster than it went in - caught up with them in a few days.
Now, the opposite is also true. Calf that shows little to no sign of actual scours, but the pathogen is wreaking havoc on his insides and he's feeling about as bad as they get. That might be what you are dealing with.
I'd keep giving electrolytes, VitB, A and D; depending on what dose of selenium you gave before and how long it's been I might repeat it, lower dosage of course. They lose a lot of electrolytes, vitamins, minerals, etc when sick or scouring. Keep the calf hydrated, that's one of the biggest things right now.
Sometimes you don't really know exactly what's wrong with an animal, but you just guess and hope for the best. As it's a young calf and there's no sign of pnemonia, I'd be inclined to look to scours and treat accordingly. In this case, both systemically (IM/SC) and orally. If you have Nuflor on hand I'd start with that IM. If you have sulfas, say SMZs (SMZ/TMP 800/160 double strength, Rx drug) I'd give those orally at 2 first time, 1/100lbs/day after that. Really, that combination should wipe out anything that calf has. LOL.
Get the calf feeling better and either raise it as a bottle calf or run it through as an "orphan" - around here they're bringing $200-300/hd. Good luck; keep us posted.
