Major Classes of Nutrients
• Water: regulates body temperature, dissolves and transports nutrients.
• Protein: builds muscle
Major Classes of Nutrients
• Carbohydrates– Provides energy for animals– Make up about 75% of most animal rations– Corn and other cereal grains are the major
source of carbohydrates
Major Classes of Nutrients
• Minerals– Calcium is on the major minerals and is found
in ground limestone– Calcium is needed in poultry feed for eggshell
development– Minerals are supplied by mineral supplements
and are a primary aid in the development of bones and teeth
Major Classes of Nutrients
• Vitamins: are needed by animals in minute quantities to help all body functions– Help prevent diseases
• Fats: only small amounts of fat are required
Classes of feeds
• Concentrates are low in fiber and high in total digestible nutrients (TDN)– Cereal grains are the major source of most
concentrates– Other sources include byproducts of grain and
animals
Classes of feeds
• Roughages are high in fiber and low in TDN– Dry roughage is hay– Green roughage includes the pasture grasses
Classes of Feed
• Silage is a roughage that results from storage and fermentation of green crops
Deficiency
• Rickets: deformity of bones in young animals caused by a deficiency of calcium, phosphorus, or vitamin D
