Adult Japanese quail (Coturnix coturnix japonica) which had been fed, since hatching, on either a conventional diet (low-fibre) or on the same diet diluted with 200 g oak sawdust/kg (high-fibre) took 8 to 10 d to adjust their food intake when their diets were interchanged. 2. Those fed on high-fibre weighed less than those fed on low-fibre diet, and body weight changed rapidly when the diets were interchanged. All the birds digested about the same weight of nutrients in a day, irrespective of diet, and this suggests that body weight differences were due mainly to differences in energy utilisation, birds fed on high-fibre diet having to expend more energy on feeding than those fed on low-fibre diet. 3. Gut size was greater in birds fed on high-fibre diet, presumably to accommodate the greater bulk of food eaten, and when the diets were interchanged the gut dimension of both groups changed at similar rates, reaching the appropriate sizes for the respective diets in 3 to 4 weeks.
成年日本鹌鹑（Coturnix coturnix japonica）自孵化后一直以常规饮食（低纤维）或用200克橡木锯末/千克稀释的相同饮食（高纤维）喂养，当它们的饮食互换时，需要8至10天来调整食物摄入量。2. 食用高纤维饲料的鹌鹑体重比食用低纤维饲料的鹌鹑轻，并且当饮食互换时体重变化迅速。无论饮食如何，所有鸟类每天消化的营养物质重量大致相同，这表明体重差异主要是由于能量利用的差异，食用高纤维饮食的鸟类在进食上比食用低纤维饮食的鸟类消耗更多能量。3. 食用高纤维饮食的鸟类肠道尺寸更大，大概是为了容纳更多的食物量，当饮食互换时，两组的肠道尺寸以相似的速率变化，在3至4周内达到各自饮食的合适尺寸。
