Common signs of energy and protein deficiency in animals

All animals require energy and proteins for different body functions. Energy is required for maintenance (to maintain the body, respiration and digestion), production (growth, milk and workforce) and reproduction (pregnancy). An animal derives energy from dietary carbohydrates. Proteins are required for the formation of body tissue. Proteins can be derived from feed and are formed by intestinal flora.

An adequate supply of both energy and protein is essential for the general health of any animal. The requirement of both energy and protein by any animal depends on the bodyweight of the animal and the degree of production expected from the animal. Prolonged deficiency of both proteins and energy would result in loss of condition and inability to be productive. 

Malnutrition if prolonged eventually leads to death. Malnutrition caused by lack of energy and proteins is more prevalent in the tropics. Animal feeds vary in their levels of energy and proteins. Straws such as rice straw and wheat straw are poor sources of both proteins and energy whereas concentrates like dairy meal may be rich in both. 

Good quality pastures may provide adequate protein and energy for maintenance and production, especially in the tropics. However, in situations of drought or overgrazing, animals are liable to receive inadequate energy or proteins from pastures.
