| Abstract | ||||
| A total number of 180 Sina laying hens 22 week of age were used in an experiment lasted 34 weeks. The experiment aimed to study the utilization of feeding laying hens different levels of Atriplex nummularia leaves meal (ALM) on the productive performance, egg quality and economical efficiency under desert conditions. Experimental hens were divided randomly into four equal experimental treatments (45 in each treatment) and randomly divided into three equal replicates (15 hens each).The first group was fed the basal diet as a control (0 % ALM), while the other three treatments were fed diets containing either 4,8 or 12 % ALM, respectively. Experimental diets were formulated to be iso-caloric (2700 kcal ME /kg diet) and iso-nitrogenous (16% crude protein), iso-fibrous (X 3.15%) and were formulated in granular form. The Atriplex nummularia leaves meal contained 3277 kcal gross energy / kg DM, 1863 kcal apparent metabolizable energy / kg DM and Total tannins as 4.2 mg/100g DM. It is worth noting that feed intake decreased (P< 0.05) with increasing ALM levels, while feed conversion ratio (g feed /g egg mass) revealed a significant (P<0.05) among ALM levels. Egg weight, egg production and egg mass showed significant (P<0.05) differences among the experimental treatments. Egg yolk, egg shell%, shape index, yolk index % did not significantly differ, while, shell thickness (mm) values were (P< 0.05) increased by increasing ALM level in the diet Increasing ALM level in the diets significantly decreased (P<0.05) digestion coefficients of OM, CP, CF, NFE% and nutritive values expressed as DCP, TDN % and ME(kcal/kg) up to 12%. However, the different levels of ALM significantly increased (P<0.05) digestion coefficient of EE. | ||||
