I have heard of several producers in my area having the same symptoms. Weight loss, watery manure, etc, etc. They never went off feed, just did poor and went down hill. To me it looks like Johnes, but these cattle were too young. All around a year or less. Wet weather, flooded grass, and pastured on strip mined ground seemed to point to the cause.
I have a 13 month heifer that sounds exactly like what you've described. Do you know if there is a vaccine available
for this type a? I gave her worm medicine and a booster of convexin 8 last week. There hasn't been any change as of yet.
Thanks for any help
There is only 1 vaccine available that I know of for Type A. The normal 7 way that we give is C&D. I'll include the info on what I found about it. Salmonella is also available, but I believe my vet said it is only in the 50% effective range. Our lab results came back that aureomycin would work, so we went with a round of that.

Aureomycin was a little of both. Treatment on anything that may have had salmonella, and hopefully knock it out on anything that wasn't showing any signs. From what I've been told, it is difficult to treat salmonella, but our lab results showed that what we had was susceptible to it.
