The objectives of this study were to examine the effect of dietary cellobiose on chicken growth and on various enzyme activities relating to fatty acid metabolism in the liver. The levels of cellobiose in the diet were 0, 0.25, and 0.5% of the basal diet. The chickens were given free access to these diets for 4 wks. Body weight gain tended to increase in the 0.25% cellobiose group compared with control and 0.5% cellobiose group, although feed intake was similar among the three groups. Feed efficiency was significantly higher in the 0.5% cellobiose group than in the control group. Abdominal fat content and plasma total cholesterol, triglycerides and free fatty acid concentrations were not different among the three groups. In the liver, there were no significant differences in activities of malic enzyme (ME) among the three groups. However, the activities of fatty acid synthase (FAS) were significantly lower and camitine palmitoyltransferase (CPT) were significantly higher in the cellobiose fed groups than in the control group. The pH of cecum content was significantly higher in 0.5% cellobiose group than in control group. These results indicate that dietary cellobiose could reduce fat accumulation in the long term.
