The initial research efforts of CRF were done with broilers. In the 50 years since, CRF has conducted over 500 experiments with broilers and broiler breeders. Nutritional areas have included; protein/amino acids, vitamins/minerals, energy, feeding programs, enzymes, ingredient evaluations, and the influence of breeder nutrition on progeny performance. Strain cross information has generally been included in most of the experiments.
Medications, equipment evaluations, problem solving, physical characteristics of feed and birds, and management techniques are some of the other areas researched. There are two (2) basic sides to nutrition. One is the nutrient needs of the birds by age, sex, health status, and management. The other side is the nutrient content of the diet (ingredients), which are digested and utilized by the bird.
Water is defined as a tasteless, odorless liquid, present in all organic tissues and in many other substances. It freezes at 32 degrees F. ( 0 C.) and boils at 212 degrees F. ( 100 C.) Water is used as the standard of specific gravity and of specific heat. Water is composed of hydrogen and oxygen. Hydrogen has an atomic weight of 1 and a valence of +l. Oxygen has an atomic weight of 16 and a valence of -2. Therefore the formula for water is H2O. Water has the ability to be a carrier for a large number of substances. The ability of water to hold materials in suspension is of vital importance. Water is probably the most unique, non-living substance.
