<br/><br/> An experiment was conducted to investigate the effect of different dietary energy and protein levels on performance of Hy-Une W36 white layers. One hundred and eighty laying hens at 1Bweeks of age were fed on nine experimental  iets containing 3 levels of crude protein (16, 18 and 20%) and 3 levels of metabolizable energy (2750,2850,and 2950kcal ME/kg feed) in a facto rial arrangement design ( 3 protein levels X 3 energy levels).
