Abstract : This study was conducted to determine the effect on the laying performance and egg qualities of mallard ducks fed with commercial layer mash containing T.gigantea leaf meal and Golden kuhol meal. Experiment was set up in a Completely Randomized Design (CRD) using 36 ducks with four treatments: T0 = 100 % commercial duck layer mash (CDLM), T1 - 90 % CDLM+ 10 % Golden kuhol meal (GKM), T2 = 90 % CDLM + 10 % Trichanthera gigantea leaf meal (TGLM) and T3 90 % CDLM + 5 % GKM + 5 % TGLM. The results of the study showed that supplementation of T.gigantea leaf meal and golden kuhol meal as part of the commercial duck layer showed significant differences on voluntary feed intake (p< 0.001), diet containing 10 % TGLM showed a very low feed intake compared to other treatment diets. Shell weight showed significant difference (p < 0.032) among treatments with T3 diet containing 5 % GKM and 5% TGLM exhibits heavier shell weight across all treatment. All other parameters; total weight gain, egg weight, egg shape index, shell thickness, yolk color, hen-day egg production and haugh unit did not differ significantly on all treatment. Even though voluntary feed intake and shell thickness shows significant difference on all treatments it potentially began to adjust to optimum level as the time progresses. Thus, it is recommended that supplementation will be tried in a much longer period.
