KEEPING LIVESTOCK HEALTHY is one of the recognized classics in its field. Small Farmer's Journal called it "a major contribution to available farm veterinary literature." Modern Veterinary Practice wrote: ". . . highly recommended to all livestock owners." And Farmstead Magazine said, "So admirably organized and indexed that its information is instantly available."<P> Now completely revised and updated, this fourth edition draws on the very latest research from experts on each of the five animals covered - horses, cattle, pigs, goats, and sheep. It presents new information on vaccines, artificial insemination, ultrasonography, disease testing, drug treatments, and diseases such as Lyme disease, Potomac fever, bluetongue, foot-and-mouth disease, and mad cow disease. This complete reference on livestock health is an invaluable guide to preventing disease through good nutrition, proper housing, and appropriate care. <P>
