I just called the lab to get my does test results and one of the girls is positive for Johnes. I don't even really know what it is, I just test for it :GAAH: I asked what I should do now and she said she would have the Dr. call me to discuss the care of my heard. What is it? How do you deal with it? Should I have her blood tested again? Any info or links you guys have would be soooo greatfully appreciated.
