International audience. Overfeeding of sorne waterfowl species results in obesity, which is mainly characterized by a dramatic hepatic steatosis induced by strong accumulation of lipids synthesized from dietary glucose in the liver. In mammals, fructose is known to be able to raise plasma triacylglycerol concentrations significantly; consequently , this may induce obesity. The aim of this study was to assess the effect of partial replacement of dietary glucose provided by corn starch with fructose on metabolism and fatty liver production in the Mule ducks. On the basis of 9.5 kg maize (132,920 kJ) given twice a day for 14 days, a supplementation of 9,800 kJwas provided in form of glucose, sucrose or high fructose
