Abstract: Different types of dietary carbohydrate and lipids are known to alter feed intake and adiposity in rodents. Long-term feeding of high-fat, high-fructose diets has been shown to alter feed intake and cause fatty liver in mammals. Such diets in combination with the addition of high fructose corn syrup (HFCS) in the drinking water may result in a similar phenotype in ducks destined for the production of foie gras. The aims of these studies were therefore firstly to assess the short-term effects of a diet rich in fat and fructose in mulard ducks and secondly to assess the long-term impact of this type of diet combined with sugar water. Despite its higher energy content, feed intake was not reduced by the FF diet, suggesting a potential alteration of satiety signals, which may impact body liver and weight under longer-term interventions in ducks destined to produce foie gras. However, HFCS in the drinking water reduced voluntary feed intake, whereas overall, FF and C had similar feed intake. In contrast to rodent and human studies, FF diets failed to induce hyperphagia and liver steatosis. In the absence of overfeeding, the long-term feeding of high-fructose, highfat diets, does not promote fatty liver.
