Book Description
In the tropics farmers have to work from a limited resource base which does not lend itself to highly productive crop and animal yields. The principles of farm management economics and the application of farm management analysis and planning can help small farmers in the tropics to produce 'a bit more' from their lots.

Book Description
Horse Feeding and Nutrition is the fourth in a series of books on animal feeding and nutrition that focuses on horse feeding and nutrition, aiming to assist in world food production. Organized into 20 chapters, the book contains basic information on horse industry, feeding problems, and importance in food production of proper horse nutrition. The introductory chapters discuss the importance of the horse industry; the art, science, and myths in feeding horses; the problems involved in supplying an adequate level of nutrients in horse rations; and the digestion of feeds. Chapters 5-10 cover concise, up-to-date summaries on macro- and micronutrients, including vitamins, minerals, protein, and water. The book goes on, examining the important interrelationships between nutrition, disease, and performance; the relative value of various feeds in horse rations; and the value of pasture and hay for horses. Chapters 15-18 focus on feeding the foal, growing horses; the performance and race horses; and the mares and stallions. The final chapters discuss purified rations for horses, antibiotics, founder, learning ability, feeding behavior, nutrient toxicity, weight equivalents, weight-unit conversion factors, and the effect of cold weather on horses. The book provides information helpful to beginners and experts in horse production. It will also be valuable for county agents, farm advisors, consultants, veterinarians, and teachers of vocational agriculture, as well as animal science students and teachers.

Book Description
Students in animal science, industry personnel involved in the feeding of animals, and professionals working for feed-mixing companies will all benefit from this current, comprehensive package - a text on the economic and nutritional aspects of feed formulations that optimize nutritional content while minimizing costs. Animal Feed Formulation applies a well-tested, easy-to-use computer program called UFFDA that illustrates the principles of least-cost food formulation. Developed in a cooperative effort by the Departments of Poultry Science and Agricultural and Applied Economics at the University of Georgia, UFFDA is menu-driven software that has the editing capabilities of a spreadsheet program for altering the ingredient and nutrient matrix. The book begins by solving a simple ration-balancing problem, providing step-by-step instructions with the computer program that any user - even one without computer training - can readily follow. It then discusses specific feed formulation techniques in terms of their practical applications and economic implications. Included are such techniques as sensitivity analysis, parametric cost and nutrient ranging, optimum-density formulation, multi-blending, and risk analysis, among others. Applying these and other techniques using the special features of UFFDA, users can select the proper ingredients, adjust proportions among nutrients, determine which feeds might require scarce ingredients, consider the risks involved in dealing with ingredients with below-average compositions, and ultimately determine the costs and nutritional content of various feed formulations. The program can be applied to determining feed formulations for any animal, including sheep, beef and dairy cattle, swine, turkeys, broilers, catfish, and horses. Practitioners who are growing animals will be able to maximize the nutritional content of their feed while keeping costs down. Professionals working in feed-mixing companies will be able to maximize profits by offering products composed of low-cost ingredients that are also of good nutritional value. Students will gain a firm background in nutritional and economic concepts, insight into how to apply them to practical problems, and an understanding of the way good nutrition and good value can be achieved by applying the latest computer technology.

Book Description
Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
