Contagious abortion is a cause of great loss to the stock growers of Utah. There is an urgent demand from nearly all parts of this State for information relative to this disease. In an effort to satisfy this demand a few facts regarding the disease as they are now known are here presented. It is not the purpose of this circular to report original research, but merely to describe the disease as it exists among animals in this State. The causes, symptoms, diagnosis, and methods of combating and controlling this great menace to the livestock industry are all considered.
