Now in its seventh edition, Animal Science and Industry remains an outstanding, easy to read introduction to the principles of animal science as well as the industry of animal production and management. It provides comprehensive coverage vital to the proper care and well-being of animals, including animal nutrition and digestion, environment, health, behavior, reproduction, lactation, and genetics/breeding. Also included are all aspects of specific production and management practices – as well as concepts in the marketing of animals and the processing of their products – as these aspects relate to beef, dairy, horse, poultry, sheep, swine, and aquaculture industries.
