Prevention and eradication of infectious abortion in cattle

Abstract

The purpose of this bulletin is a purely practical one; namely, to give cattle breeders, herdsmen, and veterinary practitioners the-fundamental facts which are now known relating to the nature of infectious abortion in cattle, and to show how these facts may be used to prevent and eradicate this disease. The facts presented herein are quite generally accepted by investigators the world over, as having been definitely established, or as being supported by such a weight of careful experimental research and clinical observation as to justify their acceptance and practical application for the control of this disease. Many of these facts have been established or verified at this Experiment Station by the writer and his research associates, Durant and Newman; and later in conjunction with Newman and Crouch and Crisler and Uren in working out different phases of the problem. Reports of these researches have been given from time to time in the Annual Reports of the Experiment Station. From this experimental work and from various other sources the facts that the writer believes will be most helpful to the groups mentioned has been prepared for publication in the present bulletin. Undecided and questionable matters have been excluded for future research. Nothing, however, of really essential practical importance has been omitted. The experience of the author and his colleagues has amply demonstrated the practicability of the measures recommended herein for combating the Bang abortion disease in cattle-which, in the opinion of many cattle breeders and livestock sanitarians, does not hold a second place even to tuberculosis in economic loss.
