Diet 1 was the control (T1), without probiotic. Chinese probiotic added at level 2g/kg for diet (T2), 2gm/kg of Iraqi probiotics for diet 3 (T3) and 2gm/kg of Korean probiotic for diet 4 (T4). The results showed a significant increase in the Final Weight Rates (56.88±0.74). distinction in Weight Gain (WG) (11.44±0.494). Weekly Weight Gain (WWG) (2.86±0.123), improved the Food Conversion Rate (FCR) (, Efficiency of Feed Conversion (EFC) , the amount of Food Intake(FI) , Relative Growth Rate (RGR) (4.00±1.72), Specific Growth Rate (SGR), and decreased the mortality, there were improved in blood characteristic included Erythrocyte and leukocyte count (RBC and WBC), Packed Cell Volume (PCV) and Hemoglobin (Hb). of the second treatment (Chinese probiotic) compared to the another treatment, the study showed that the second treatment the best values for all diets and that the proportion of added the Chinese probiotic 2g/kg feed had a positive effect for all the studied parameters. | ||
