I have a mystery illness and would apreciate any input. Here's the deal: I have a first calf heifer that apparently starting wasting away some time prior to calving. She's in a very healthy herd (vacs,wormed, etc). She had a calf and it became very apparent that she was going down physically. We penned her and the calf and tried to feed her but there was no appetite. On advice of a vet, we hit her with anti-biotics and cortisone. She began to drink water and eat a little. I had the vet come on out and look at her. He found no obstructions on either end, no mastitis, etc. She still has her baby teeth. There was no fever. He thought it could be kidney failure but blood tests proved otherwise. It's been a couple of weeks...she will eat about 4-5 gallons of feed daily but very little hay - is drinking plenty of water now. Tends to slobber a lot. I actually think she's recovering but would like to know what the board thinks happened?
