The aim of the study is to examine the effects of chitosan in the ration on Tegal duck performance. The dose of chitosan used ranging from 0.0%, 0.5%, 2% and 2.5%, mixed into the basal ration. The basal diet used iso-protein and isoenergy, with protein content of 15.34% and Metabolic Energy 2809 kcal / kg (NRC, 1994). Parameters measured were feed intake, duck day production (DDP), total egg weight and feed conversion. This study uses a completely randomized design (CRD) consisting of 4 treatments and 5 replicates and each replicate consisted of two ducks. The basal diet (R0) = without chitosan as a control, R1 = 0.5% chitosan, R2 = 2% chitosan, and R3 = 2.5% chitosan. Data were analyzed using SPSS 16 statistical program (Statistical Package for Social Science). Results indicated that chitosan showed no significant effect (P> 0.05) on feed consumption, duck day production, total egg weight and feed conversion. In this study, treatment of chitosan 2.5% (R2) gives the best results on day duck production, total egg weight and feed conversion. From the daily egg production (DDP), treatment R2 has a result of 59%, larger than R0 (57.76%), R1 (44.1%) and R3 (46.9%). Total egg weight for R2 = 3597.7 (73.42 g / grain) also show a greater number than the treatment R0 (2769.72), R1 (2662.46), and R3 (3403.14). On feed conversion, R2 showed the smallest (1.93) compared to R0 (3.06), R1 (7.4) and R3 (2.31). This means duck in treatment R2 more efficient of feed consumption, 1.93 kilograms to produce one kilogram of eggs.
