Abstract
Phosphorus is available in inorganic and organic form in plants mostly in the seeds and cereals. Only 30% of it freely available and rest is present in the form of phytate-bound phosphorus known as phytic acid. Mammals have enzyme called phytase, a chemical found in their digestive system that breaks the phytic acid and releases the bound phosphorus. However, poultry lacks the enzyme. The feed needs to be supplemented with inorganic phosphorus sources, thereby making the formulated ration expensive. Therefore, the enzyme phytase could be added in the poultry ration @ 500 IU and 1000 IU ton-1 feed which may be more cost efficient and economical. Addition of phytase enzyme in poultry ration would results in better utilization of dietary phosphorus and other minerals like Ca, Zn, Cl, etc. It also improves digestibility of amino acid and ultimately results in better growth and performance of the poultry birds.
