Two experiments were conducted for studying the utilization of sago palm tree in broiler duck rations. In the first experiment, the nutritive value of sago palm tree (grind and dry) was determined by using the proximate analysis. Moisture, crude protein, crude fat, crude fiber, total ash, nitrogen free extract, calcium, phosphorus and gross energy (GE) were about 8.32, 0.37, 1.05, 1.77, 1.66, 87.55, 0.04, 0.31 % and 4.01 K cal/g respectively. In the second experiment, sago palm tree was used to replace 0, 10, 20, 30 and 40 % of the rations. In the experiment 320 one-day old Cherry valley ducks were used and separated into five treatments, each treatment consisting of three replications. For one treatment 64 ducks were used. The results suggest that the feeding consumption and growth of broiler ducks in the first three weeks decrease (P0.01) when the % amount of sago in the ration increased. In eight weeks, the average bodyweights were 2636.50, 2604.11, 2456.84, 2366.52 and 2349.60 g; Feed conversion rates were 3.598, 3.711, 4.033 4.107 and 3.953.; Total feed consumes were 9301.44, 9478.93, 9713.21, 9518.33 and 9099.85 g in 0, 10, 20, 30 and 40 % sago of the ration respectively. These results suggest that sago palm tree can be used in broiler duck ration at about 10 - 20 % of sago level.
