Effect of varying dietary protein levels on productive performance of new synthetic line Dayananda H.V., Umakantha B., Devegowda G. Department of Poultry Sciences, University of Agricultural Sciences, Hebbal, Bangalore - 560 024. Abstract Optimum protein requirement of a new synthetic eggtype line developed at University of Agricultural Sciences was detennined in a simple randomised design. Four experimental rations were formulated with 15, 16.5, 18 and 19.5% protein levels atisocaloric energy (2600 Kcal ME/kg) and fed to 480 pullets for 4 periods of 28 days each. Dietary protein had significant (p<0.05) effect on hen housed egg production, feed efficiency and egg weight. Hen housed egg protection was significantly (P<0.05) higher at 15% protein. Feed consumption was significantly (p<0.05) less at 15–18% than at 19.5% protein. Egg weight was better at 15 & 19.5% protein levels. Protein levels did not affect Haugh unit and shell thickness. Feed efficiency was significantly (P<0.05) superior with diets containing 15, 16.5 and 18%. Considering the overall performance, 15% dietary protein appears to be adequate for optimum performance of new synthetic egg type line.
