Abstract
A production trial was carried out utilizing 200 single comb White Leghorn hybrid Athulya layers to study the economics of phytase supplementation at three different levels in low energy-protein diet with reference to the cost of egg production and net profit per egg for a period of 20 weeks. Phytase was supplemented at 0, 500 and 1000 units/kg in low energy, protein and energy-protein layer diets containing available phosphorus of 0.30% from 21 to 40 weeks of age. Significantly (P < 0.01) lower cost of production of an egg and increased net profit were recorded among various phytase supplemented dietary treatments when compared with standard layer and unsupplemented diets fed treatment groups.
Key words: Phytase, layer, economics.
