The aim of the present study was to evaluate the effects of three fibres (sugar-beet fibre, guar gum and inulin) incorporated in the basal diet of healthy dogs at 7 per cent of dry matter (DM). Parameters examined included stool output, water consumption, nutrient digestibility and fasting and postprandial plasma metabolites. All fibres increased wet faecal output; an increase in faecal DM output being observed with sugar-beet fibre only. Sugar-beet fibre and inulin increased daily water consumption. Sugar-beet fibre and guar gum decreased DM digestibility. The three fibres diminished organic matter and crude protein digestibility while ether extract digestibility was decreased by guar gum and inulin. Guar gum induced lower postprandial insulin, alpha-amino-nitrogen and urea plasma concentrations. Guar gum also lowered fasting cholesterolaemia. Sugar-beet fibre and inulin showed no metabolic effects. These physiological properties suggest that guar gum would be a suitable ingredient for dietary therapy of chronic diseases such as diabetes mellitus or hyperlipidaemia in the dog.
本研究的目的是评估三种纤维（甜菜纤维、瓜尔豆胶和菊粉）以干物质（DM）的7%添加到健康犬基础日粮中的效果。所检测的参数包括粪便排出量、饮水量、营养物质消化率以及空腹和餐后血浆代谢物。所有纤维均增加了湿粪便排出量；仅甜菜纤维使粪便干物质排出量增加。甜菜纤维和菊粉增加了每日饮水量。甜菜纤维和瓜尔豆胶降低了干物质消化率。这三种纤维降低了有机物和粗蛋白消化率，而瓜尔豆胶和菊粉降低了乙醚提取物消化率。瓜尔豆胶使餐后胰岛素、α-氨基氮和血浆尿素浓度降低。瓜尔豆胶还降低了空腹时的胆固醇血症。甜菜纤维和菊粉未显示出代谢作用。这些生理特性表明，瓜尔豆胶可能是犬糖尿病或高脂血症等慢性疾病饮食治疗的合适成分。
