Abstract
The study had been designed to determine the positive effect which may be result from microbial phytase and Alfalfa alcoholic extract (plant phytase) addition to the broilers diet to compare the efficiency of these two types of the enzymes The study lasted for fourty-two days. Seven hundred one day chick broilers were divided into three groups , first (control): 200 chicks received basal diet, second (T1): 200 chicks received basal diet and 0.2g/L of Alfalfa alcoholic extract supplemented with drinking water, third (T2): 300 chicks received basal diet supplemented with 1000FTU/Kg of microbial phytase. The productive features were evaluated by the following parameters: mean of weakly body weight (g), weight gain (g), feed consumption rate (g), feed conversion rate (g/g), dressing weight ratio, mortality ratio and special parameters to evaluate economic and productive performance of the broilers, which involved : production index (%), economic index (%), European production efficiency factor (%) and growth rate (%) for each treatment. The study revealed significant differences in some parameters between the two treated groups, in comparison with control as follows:- 1. Significant increase (P<0.05) in weekly body weight (g), body weight gain (g) & dressing weight ratio (%). 2. Increase in weekly feed consumption (g) and highly increase in all special economic and productive parameters & Decrease in mortality ratio (%).
