I just received a call from a friend who's mature cow that isn't due to calve until January has the following symptoms: She is standing by herself, not fighting flies, he says the flies have really eaten her up, she has a fever, and acts like she may be blind. He says her condition is great, she's not thin or gaunted up, he would take her in the show ring tomorrow. This is a guy who knows his cattle. We are stumped. I told him to call my vet, the fever indicates illness, but does anyone have any ideas? We live in Western Oregon.
