jaw can be a sign of Johne's disease
jaw", also called submandibular edema, is a sign very typical
of Johne's disease. The cause of bottle jaw is a lack of protein
in the serum, particularly albumin, due to the decreased function
of the intestine. Johne's disease is a protein-losing enteropathy.
Parasitism and some other disease conditions in cattle can also
cause bottle jaw.
