I lost a 2 week old calf today. And I was wondering if anyone could give me an idea of what happened. In less than a 24 hour period, she went from a healthy animal to deaths door. Calling the vet, she only said that bacteria had entered her brain. Has anyone had this happen to them, and what can I do to prevent this from happening again. The heifer calf was a bottle feed baby and lived away from the rest of the herd.
