Abstract
Phosphorous is present as phytate (phytic acid) form in plant which is essential for germination of seed. Phytic acid interferes with the bioavailability of most of the nutrients required for broiler production mainly macro minerals. It chelates minerals (Ca, P, Zn, Mg, Mn, Cu) and complexes with fatty acid and reduce their availability for digestion. It deactivates energy and protein digesting enzymes and decreases digestibility of crude protein and fat. phytic acid-minerals complexed (phytate) reducing the availability minerals as well as that of the PP to the monogastric. Phytic Acid-Ca- Complex Resulted in to Phytate-Ca-Fatty Acid Complex A Metalic Soap Formation Which Ultimately reducing the fat digestibility. Monogastrics are lacking of gut phytase enzymes hence they are more prone to suffer due to phytate in the diets. Hence, Supplementation of phytase in broiler diets the degrade the various phytate complexes with nutrients and improved its bioavailability. Further, effort should be made to hunt newer sources of enzymes with improvement of its efficacy should be worked out.
