The experiment was carried out to study the response of additional leaves of purple sweet potato (Ipomoea batatas L.), noni (Morinda citrifolia L.) and betle (Piper betle L.) in diets on performance of bali duck. The experiment used completely randomized design with four treatments consists of control diet A (diet without leaves), diet B (diet containing with purple sweet potato leaf, diet C (diet containing noni leaf), and diet D (diet containing beetle leaf). Each treatment conducted with three replications and each replications consist of five ducks. The variables observed were feed consumption, antioxidant consumption, body gain, and FCR and of bali ducks. Feed consumption of bali ducks in treatment B, C and D were significantly lower, however, the antioxidant consumption significantly higher than control diet. In contrast, body weight gain in treatments B, C and D increased significantly but decreased FCR compared to treatment A. The treatments of B, C, and D can increase the carcass weight, and carcass percentage significantly. These were offered to bali ducks could increase percentage of meat and bone but significantly decrease fat of carcass including their skin for bali ducks fed with A (control treatment). It can concluded that the leaves of purple sweet potato, noni, and betle leaf in diets improved the performance and carcass of bali ducks.
