To investigate the effects of force-feeding and dietary cereals on feed conversion, hepatic lipid accumulation and plasma components, Pekin ducks were force-fed on a corn or barley based diet from 43-54 days of age, and the following results were obtained.Force-feeding markedly increased body weight gain and decreased feed/gain ratio. No significant differences were found in body weight gain and feed/gain ratio between experimental diets.Force-feeding significantly increased the weights of liver, pancreas, kidney, heart and abdominal fat. Ducks fed on barley based diet had a lighter liver compared to that fed on corn based diet.Force-feeding caused a relatively higher concentration of liver total lipid and significantly lower concentration of liver non-lipid dry matter. Feeding barley based diet significantly decreased the concentration of liver total lipid and esterified cholesterols, and the ratio of esterified to total cholesterol compared to the corn-based diet. The frequency of occurence of liver fatty metamorphosis was very high in the ducks force-fed on corn based diet, while no ducks fed on barley based diet were recongnized as fatty metamorphosis in liver.Force-feeding significantly elevated the concentration of all plasma components determined except for esterified cholesterol. Plasma urea was significantly higher in the ducks fed on barley based diet.
