Poultry Nutrition, Physiology, and Metabolism

[Jeffery Escobar]

Nutrition is the science that studies nourishing of the body and the biological function of nutrients and other dietary substances in relation to the maintenance, growth, reproduction, health, disease, and other biological processes of an organism. Nutrition also studies the digestive and metabolic processes by which an organism takes in and assimilates food for maintenance, which is the basic metabolism to sustain life, as well as productive purposes like growth, reproduction, milk or egg production, work, wool or hair production, and more. Assimilate means to change the food into a form that can be taken up or absorb by the body and made a part of the tissues, which directly deals with digestive physiology processes.
