Ok here's the situation; I have two cows that I've had now for a year, they've been perfectly healthy until a few days ago when one of them stopped eating much hay, now she won't eat at all and mostly lays around. She has a snotty nose (greenish yellow discharge). It's only about 60 degrees here and the sun is out, she has a shelter. I have an appointment to have them both butchered in two days. So what should I do? I can't give her an antibiotic, but will the meat be compromised by her illness?
