Background and Objective: The Pitalah duck is one of Indonesiaʼs native ducks that has a uniform physical form and a genetic composition that is well adapted to environmental conditions. However, the Pitalah duck has a high feed conversion, so it is necessary to improve its feed efficiency. The purpose of this study was to determine the effect of the balance of energy and protein in the diet, which includes a probiotic, Bacillus amyloliquefaciens (B. amyloliquefaciens), on the performance of the Pitalah duck. Methodology: In this study a 3×3 group-randomized factorial design was employed that included 2 factors with 3 groups of body weight as replicates. Factor A is the energy level (E1: 2800, E2: 2700 and E3: 2600 kcal kgG1) and factor B is the protein level (P1: 18, P2: 17 and P3: 16%). Live weight, percentage of carcass, percentage of abdominal fat and income over feed cost were the measured variables. Results: The results showed thatthecombinationof energy level andprotein level andan interaction betweenthesefactors hada significant impact (p<0.05) on the live weight, percentage of carcass, percentageof abdominal fat and increasedincomeover feedcost. Conclusion:The combination of energy and protein, along with administering 2000 ppm of the probiotic B. amyloliquefaciens, can improve the efficiency of the ration while decreasing the need for duck ration energy by 3.57% and decreasing the protein requirement by 5.56% at an energy level of 2700 kcal kgG1 and 17% protein in the ration.
