We had a cow that had a calf about a week ago. Since then she will not eat. She wasn't drinking either. We contacted our local vet - he suggested putting water in a tub and she did finally drink about 2 - 5 gallon buckets of water. Our vet came today - put her in the shoot to check her out. We thought it could be hardware disease but he said her heart & lungs sounded good. He sleeved her to make sure she had cleaned herself good after the birthing and that was fine.. He gave her 2 bottles of calcium thinking maybe she was deficient because of nursing the calf but that did nothing. He mixed up several things and gave her a shot in her neck. She did have a fever. She got down in the shoot and we couldn't get her up. We went over a couple hours later and she still had not gotten up so we pushed her back into the stall and propped her up so she wasn't laying on her side. The vet said he had no idea what it could be.
