Phosphorous is one of the vital minerals in animal nutrition. After calcium, it is the second most mineral found in the animal body, predominantly in animal teeth and bones. Moreover, phosphorus plays an important role in the development and maintenance of skeletal tissue, maintaining osmotic pressure in body fluids, acid-base balance, energy utilization, protein synthesis, growth of cells, the efficiency of feed utilization, and fertility. Deficiency of phosphorous has different effects in different animal species, to name a few deficiencies of phosphorous in laying hen causes osteomalacia as well reduction in shell thickness

Minerals that are required by animals in small amounts for their development and growth are known as trace or microminerals. When the source from which these minerals are obtained is organic then these minerals are known as trace organic minerals or mineral chelates.
