This study envisaged to asses and analyse the effect of phytase enzyme incorporation in the feed of layer chicken ATHULYA (ILM-90) to reduce phosphorus excretion through faeces and thereby control of environmental pollution. The study was conducted at AICRP on Poultry , Mannuthy Thrissur, India. Addition of Phytase enzyme in the poultry feed significantly (p<0.01) reduced phosphorus excretion in the droppings of birds (g/Kg DM intake). Bioavailability of phosphorus in the enzyme treated groups was significantly improved. The effect of three levels of phytase viz., 200,300 and 400 units per kilogram in the low available phosphorus layer ration on comparison with birds reared on standard layer ration showed phosphorus availability to chicken in the enzyme treated groups were more , and hence excretion of phosphorus is reduced, which helps for control of pollution of nearby water sources.
