Johne's (pronounced "Yo-nees") disease is a chronic, contagious bacterial disease that affects the small intestine of ruminants such as cattle, sheep, goats, deer, antelope and bison. All ruminants are susceptible to Johne's disease.
Johne's disease is caused by Mycobacterium paratuberculosis, a hardy bacterium that embeds itself in the wall of the lower part of the small intestine known as the ileum. As an immune response, infected tissues attempt to regenerate healthy tissue which leads to visible thickening of the intestines. This prevents nutrient absorption, resulting in weight loss. Late in the infection, antibody production by the animal can be found in serum of animals and is an indicator that clinical signs of disease and death from the infection will soon follow.

What causes johnes in dairy cows?
Johnes' disease is caused by Mycobacterium aviumsubspecies paratuberculosis. It is a chronic disease of the intestinal wall that causes pipestream diarrhea in the face of a good appetite; the cattle end up wasting away due to malabsorption diarrhea and effective starvation. Most producers will cull the cow for production reasons before it gets too bad; these animals are often taken to slaughter.

Signs of Johnes disease and weight loss in dairy cows?
The second part to this question is easy: when you weigh a cow one day, and weigh her again 24 or 36 hours later, you can tell she'll be loosing weight if she's lost weight during that time period. She'll also look thinner if she's losing weight. As for the second part, Johnes disease is a sign of cows becoming quite thin to the point of emaciation, and don't gain weight even when you try to feed them concentrate feed to get their weight up again. She will also have intermittent diarrhea and constipation. Feces will look watery but will have no blood in them and will have a normal odor. Often a fecal test will reveal if a cow has Johnes disease or if she just has internal parasites. Johnes disease is always fatal, with the animal living from a month to a couple years. There is no satisfactory treatment for this disease that has yet been found.
