Paperback. Condizione: New. Print on Demand. This book by the author focuses on the maintenance rations of farm animals, such as cattle, horses, sheep, swine, and poultry. As a general rule, maintenance rations include only what is required for the bare sustenance of the animal with no consideration given to milk production, work, growth, or other considerations, which must be calculated and added to the maintenance ration. The determination of the maintenance ration depends on laboratory analysis of the feed and the calorimetric measurement of the animal's heat production. The author examines the energy requirement for maintenance and the relationship between the maintenance requirement and live weight, the protein requirement for maintenance, and the optimum of protein. The author also discusses the relative values of proteins, with differences in their constitution and the proportions of their constituents. The book is a key reference for farmers, nutritionists, and researchers in the field of animal science.
