[QUOTE="TheBullLady, post: 20120, member: 173"] Johnes is a disease I'm afraid we'll be seeing a lot of in the near future in the beef industry.. especially if it's confirmed that there is a link between that and the "human form", which is Crone's disease. Dairy herds have been plagued by this disease for years, primarily because most dairy cattle are kept in close confines, which makes it much easier to spread. It's spread via manure, so cattle that are in a lot or calving in a small area are very suseptable. The best thing, in my opinion, that you can do in a beef herd is cull deeply. I wouldn't keep any progeny out of a Johne's cow.. and it may take a few years to get it all out of the herd. Generally stress will bring on symptoms, ie: weaning or calving. Cows are generally 4+ years of age before you'll see symptoms, but by then they have had a chance to infect more of your herd. Good luck! [/QUOTE]
