The overall purpose of this book is to draw attention to some of the factors that reduce the effriciency of livestock production in a region of the world in which it is most vital--the so-called "warm climates" lying between latitudes 30 degrees North and 30 degrees South.  High air temperatures and rainfall distribution in this region create conditions which influence the efficiency of performance of livestock directly by affecting the animal's body functions and indirectly by causing flucturations in feed supplies and increasing the incidence of animal diseases.
