I have a small flock, and haven't worried too much about sheep disease. Then I began to hear about Johanne's disease and scrapie. I thought, I don't have so why worry? Now I worry, not because my flock is ill, but it seems to be a reality anywhere. I am rambling a bit, but my question is this: is Johanne's disease and scrapie the same, or are they two completely seperate aflictions? From what I have read thus far, they appear to have the same symptoms. Can someone please describe both diesase to me please? Thank you.
