Dry beans (Phaseolus vulgaris L., Fabaceae) are a low glycemic index food containing protein, fiber, minerals, essential vitamins, and bioactive compounds and have not been evaluated for inclusion in commercial canine diets. The objective of this study was to establish the apparent total tract digestibility and safety of cooked navy bean powder when incorporated into a canine diet formulation at 25% (wt/wt) compared with a macro- and micro-nutrient matched control. Twenty-one healthy, free-living, male and female adult dogs of different breeds were used in a randomized, blinded, placebo controlled, 28-d dietary intervention study. Apparent total tract energy and nutrient digestibility of the navy bean powder diet were compared with the control diet. Digestibilities and ME content were 68.58 and 68.89% DM, 78.22 and 79.49% CP, 77.57 and 74.91% OM, 94.49 and 93.85% acid hydrolyzed fat, and 3,313 and 3,195 kcal ME/kg for the navy bean diet and control diet, respectively. No differences were observed between the groups. No increased flatulence or major change in fecal consistency was observed. Navy bean powder at 25% (wt/wt) of total diet was determined to be palatable (on the basis of intake and observation) and digestible in a variety of dog breeds. No changes were detected in clinical laboratory values, including complete blood counts, blood biochemical profiles, and urinalysis in either the bean or control diet groups. These results indicate that cooked navy bean powder can be safely included as a major food ingredient in canine diet formulations and provide a novel quality protein source, and its use warrants further investigation as a functional food for chronic disease control and prevention.
干豆（菜豆属，豆科）是一种低血糖指数食物，含有蛋白质、纤维、矿物质、必需维生素和生物活性化合物，尚未评估其是否可包含在商业犬粮中。本研究的目的是确定在犬粮配方中以 25%（wt/wt）添加煮熟的海军豆粉的表观全肠道消化率和安全性，与宏量和微量营养素匹配的对照饲料进行比较。21 只不同品种的健康、自由生活的雄性和雌性成年犬参与了一项随机、双盲、安慰剂对照、28 天饮食干预研究。海军豆粉饮食的表观全肠道能量和营养素消化率与对照饲料进行了比较。消化率和 ME 含量分别为 68.58%和 68.89%DM、78.22%和 79.49%CP、77.57%和 74.91%OM、94.49%和 93.85%酸水解脂肪以及 3313 和 3195kcal ME/kg 海军豆饮食和对照饮食，两组之间无差异。未观察到组间有增加的腹胀或粪便稠度的主要变化。海军豆粉在总饮食中的 25%（wt/wt）被确定为可接受的（基于摄入量和观察），并且在各种犬种中可消化。在豆粉或对照饮食组中，均未检测到临床实验室值的变化，包括全血细胞计数、血液生化谱和尿液分析。这些结果表明，煮熟的海军豆粉可以安全地作为犬粮配方中的主要食物成分，并提供一种新型的优质蛋白质来源，其用途值得进一步研究，作为控制和预防慢性病的功能性食品。
