Effect of The Balance Energy and Protein Ration on the Growth of Pitalah Duck Which is Given Probiotic of Bacillus amyloliquefaciens

Abstract

The purpose of this study is to determine the balance of energy and protein in the ration which is given probiotic of Bacillus amyloliquefaciens on the performance of Pitalah duck. This experiment was using a group-randomized design with a 3x3 factorial pattern with three groups of body weight as replications and two factors. Factor A is energy level (2800, 2700, and 2600 kcal/kg), Factor B is protein level (18, 17, and 16%). Feed consumption, body weight gain and feed conversion were measured. The results showed that combination of the energy level and the protein level as well as the interaction of both factors are significant (P<0.01) towards feed intake, body weight gain and feed conversion. It can be concluded that the combination of energy and protein with administering Bacillus amyloliquefaciens probiotic can decrease 3.57% energy needed on duck ration and decrease 5.56% protein needed with 2700 kcal/kg energy balance and 18% protein in the ration.
