Been working with a Dairy farmer that has been working with a high death rate on calfs. I have been getting his bull calfs. I have been running about 40% death loss on MR and he is at 99% on pastureized cows milk. Two live calfs (1 sick, 1 not) have been sent in for disection. So far the vets are stumped. Here the deal, I have kept records on all the bulls I done to date (15). Of that 5 have died, 2 are in a bad way, 2 are healthly, and 2 are to new to tell, 4 are on soild food. Basicly one of two things happen. The calf will be fine for 4-7 days, get the scours and die in the next 5 or 6 days. Suffer from massive weight loss and infection problems (starve to death). Or it will start out with scours and be dead in a week (same symtoms). I had posted about some of this a few weeks back (egg and oatmeal). In that one I had mention that another fella that had been working with these calfs hadn't had any problems. But that information was basicly coming second had. I have since found out that is not the case. He is having the problems as well. Pouring over my notes, I my have over looked something. If I get a calf to go on a bucket. He will survive. All deaths happen on the bottle??? So I was looking and searching on the net about the digestive process calfs go thru. Didn't find much but did run across an article that stated "when a calfs head is titled up a mussle closes and the milk bypasses first stomac(s) (sp) and goes directly into one of the others". So this got me to thinking. I had suspected Cocilladosios (sp). A pearisite in the gut that was damaging the intestins and preventing absorbtion. However the treatment (back to the notes) didn't seem to help until they start on a bucket. So maybe its the bucket, or milk entering the first stomac, rather than the treatment that is causing improvement. All calfs that make it to soild food survive. Any information on digestive proccess or a known bug that affect the final stages of digestion could be a big help. BTW - The oatmeal trick (cooked, no seasoning) seem to reduce the weight loss problem on the two that received it. But didn't seem to help the scours. I suspect some of it was getting in the first stomac and thus make it digestable. Even though the bulk of the milk wasn't.
