Growing chickens were fed three levels of biotin, 0, 20, and 100 micrograms/kg diet, and four different carbohydrates, glucose, dextrin, sucrose, and sorbitol, in order to study the effect of dietary carbohydrates on the level of cecal biotin. Dietary sorbitol was found to enhance the concentration of cecal biotin at suboptimal levels of dietary biotin, while dietary dextrin had the opposite effect. When the dietary requirement of biotin was met, cecal biotin greatly increased in the presence of dietary glucose, sorbitol, and sucrose but remained at a low level when dextrin was the dietary carbohydrate. Dietary sorbitol increased significantly the dry weight of ceca over those of birds fed other carbohydrates.
