Effect of Phytase Enzyme Supplementation in Low Energy-Protein Layer Diet on Tibial Mineral Contents
An experiment was carried out using 200 hundred Athulya birds divided into 10 treatments (T1-T10) to find out the effect of phytase enzyme on tibial mineral contents. Phytase was supplemented at 0, 500 and 1000 units/kg in low energy, low protein and low energy- protein layer chicken diets containing available phosphorus of 0.30% from 21 to 40 weeks of age. A standard layer ration was offered to birds in T1. Experimental diets from T2 to T10 were formulated with two levels of crude protein (18 and 16 percent) and two levels of metabolisable energy (2600 and 2400 ME kcal/kg diet). After the laying period, four birds from each treatment were randomly selected, slaughtered and data on tibial mineral contents viz. tibial ash. calcium and phosphorus were measured. The tibial mineral contents viz. tibial ash. calcium and phosphorus showed significant (P<0.01) increase among phytase supplemented treatments.
