Abstract
Extract The nature of Johne's disease is such as to make studies on distribution and intensity extremely difficult. Farmers have a tendency not to report suspected cases, and methods of diagnosis are by no means perfect. Outbreaks of Johne's disease, in the sense of many cattle dying at one lime of the disease, do not usually occur; the disease is insidious in nature, and losses are spread out over a period of time.Keywords
