[QUOTE="Jeanne - Simme Valley, post: 298855, member: 968"] Johnes is spread thru manure & colostrum (mainly) and generally only newborns thru a few months of age are susseptable (sp?) to being infected. It can "live" on the ground for many years. If infected, it never rises it's ugly head until (usually) a first calving heifer. Stress makes it show up - than when the stress is relieved (calf weaned) - they may show NO SIGNS. Heavy milking cows can lose a lot of weight with a 5 month old calf. But the combination of scours & wt loss is concerning. BUT, as said, loose stool & diarhea are two different things. "Generally" Johnes scours are watery stool - profusely. Testing would be in order - talk to your vet. To the best of my knowledge, the meat is unaffected. Johnes attackes the lining of the stomach, causing it to be unable to process the food they eat. Once they have it, there is no cure and they "shed" on and off the rest of their lives . Someone has a great web site describing Johnes. You can "search" on this board & find lots of info. [/QUOTE]
