In: Egyptian Journal of Nutrition and Feeds 2011.v14(3)Summary: A total number of 180 Lohmann hens 18-wks-old were randomly divided into 9 experimental groups of 5 replicates each. A 3 x3 factorial design containing three levels of crude protein (16,18 and 20%) and three levels of total sulfur amino acids (0.67. 0.72 and 0.77%) to study the effect of dietary crude protein and total sulfur amino acids (TSAA) on egg production and some blood constituents during the period from 18-34 wks of age. Egg number and egg mass were increased (P<0.01) for hens fed diets of 20 and 18% CP versus that of 16% protein through the period from 26-30 wks of age. There were no significant effects of dietary protein levels on globulin. uric acid and creatine. while total protein. albumen and urea of hens fed the high and moderate protein diet were significantly greater than those of hens fed the low-protein diet from 30-34 wks.
