| Abstract | ||
| In this experiment three strains of broiler were used .They were Eba,a 2000 , Ross and Lohman , treated with four different rations ( premix with or without probiotic , and protein concentrated with or without probiotic ) in trial up to the age of eight weeks Probiotic dissolved in water with on average 0.20gm / bird during the second and third days of age . The results revealed the following : -1- The strain has significant progressively effect on the product performance of broiler . Eba,a strain has exceeded in body weight as compared with other hybrid strains . 2- Eba,a strain showed significantly higher feed consumption improve feed conversion efficiency and dressing percentage than other strains , however the strain has no significant effect on mortality . 3- The interaction effect of the strain and feed treatment was noticed Eba,a with premix with probiotic excel significantly in body weight and feed conversion than other interaction in this study . 4- Probiotic and premix cause an increase in production index value and economic figure for the Eba,a strain which significantly exceeded as compared with Ross and Lohman strains | ||
