ABSTRACT
Animal nutrition, like medicine, is a field for both scientists and practitioners, and it can be considered a unique discipline because of its specific objective: improving the survival, growth, and health of animals by understanding their metabolism and the roles of dietary nutrients. The traditional method used to determine the nutrient composition in feedstuffs and animals is known as the proximate or Weende analysis, which was devised in 1865 by Henneberg and Stohmann at the Weende Experiment Station in Germany. The knowledge of physiology helps us understand how ingested food is digested, absorbed, and assimilated in animals to sustain homeostasis in the body and support growth, development, reproduction, physical activity, and health. The interaction between nutrition and physiology has given rise to a research area known as nutritional physiology, which is the study of how nutrients influence physiological processes in the body and vice versa.
