A study was carried out aiming to evaluate the utilization capacity of water hyacinth in the diet of local goose. It was a complete randomized design with 5 treatments corresponding to 5 diets and 3 replications. Four geese balancing in sex were used in one experimental unit. The treatments included C100, C85, C70, C55 and C40 corresponding to the concentrate (rice bran, soybean, bone meal and vitamin premixes) fed geese at the level of 100, 85, 70, 55 and 40 % (based on the C100 diet), while the water hyacinth was offered ad libitum. The results shown that the reduction of concentrate of 100, 85, 70, 55 and 40 % in the geese diets corresponded to the daily concentrate intakes of  263, 225, 184, 146 and 106 g DM, respectively. This resulted in the increase of water hyacinth intakes of 0, 23.5, 34.5, 43.6 and 37.9 g DM, respectively. The intakes of DM, OM, CP, NDF, CF, EE and ME were significantly different (P0.05) for the C100, C85, C70 and C55 treatments, and they were 4458, 4214, 4071 and 3861 g/goose, respectively. The daily weight gain (DWG) was not significantly different (P>0.05) among the C100, C85 and C70 treatments. Apparent feed and nutrient digestibility and digestible nutrients were significantly different (Pad libitumwater hyacinth could give better profits.
