PROTECTION OF DOMESTICATED ANIMALS

vice in the eradication of infectious and epizootic diseases. Advancement is being rapidly made, but before the desired results can be attained much additional knowledge must be acquired. Those engaged in this kind of investigation are constantly encountering difficulties by way of limited facilities and funds. The greatest danger, however, that threatens progress in the prevention of disease is the propaganda against vivisection. The time has passed when unnecessary pain is to be tolerated in experimental work. The men and women who are engaged in work requiring the use of animals are sensible of their discomforts. Nevertheless, in the grim warfare against suffering and disease it is often necessary to utilize a few animals for diagnosis. A larger number are required for the preparation of serums and vaccines for therapeutic and immunizing purposes. No one fails to appreciate the importance of minimizing the number of deaths among animals, thereby checking the unnecessary loss from disease. To accomplish this it is sometimes necessary to sacrifice a few individuals in order that epizootics may be checked. In all great crises the lives of a few have been willingly sacrificed in order to save the many. Thus the few animals that were used in the investigation of the nature of Texas fever in cattle and the means by which its virus is transmitted have saved thousands and thousands of cattle from suffering and death from that disease. It is to be hoped that eventually science may give us a substitute for experimental animals. However, the protection against disease that is afforded the flocks and herds of our country warrants the most hearty and loyal support of the principles underlying the present methods of control.

It is impossible in the limits of a single article to discuss adequately all of the essential factors involved in bringing about the desired protection of domesticated animals. Great improvement has been made in the methods usually referred to under the term of the care of animals, such as gentle handling, proper exercise, suitable food and shelter. Betterments along these lines will be made as fast as the acquisition of new knowledge of their physiological requirements permits. Better care of the sick and injured will follow as fast as the owners come to a realization of their obligations to their animals. The suffering and losses from infectious and epizootic diseases will decrease in direct proportion to the application of rational methods for their prevention. The organized efforts to do away with cruelty are more rational and more effective because they are based on scientific principles. The ideal conditions to be attained will come only through the growth of knowledge of the requirements of animals and a deeper consciousness of man's responsibility over dumb creation.
