The growing pet food market is continuously in search for novel ingredients. Legumes such as faba beans (FB) are increasing in popularity and are known to benefit human health, but little is known about their use in pet foods. The objective of this study was to determine the effect of dehulled FB utilization by dogs. Experimental diets were extruded with 0%, 10%, 20%, and 30% FB inclusion (FB0, FB10, FB20, and FB30, respectively). Beagle dogs (n = 12) were fed the diets for 9-d adaptation with 5-d total fecal collection in a replicated 4 × 4 Latin square design. Apparent total tract digestibility (ATTD) was determined by external marker Cr₂O₃. At the culmination of each period, blood samples were collected from brachial venipuncture for complete blood count and blood chemistry. Palatability was determined with a 2-bowl test (n = 20). Means of blood parameters were separated by multivariate analysis of variance (MANOVA) with the aid of statistical software (SAS v9.4). Contrasts and least square means of fecal parameters and ATTD were computed. Significance level was considered to be α = 0.05. Dogs ate all food on offer and maintained body weight. There was no difference (P > 0.05) among treatments (FB10, FB20, and FB30) and the control (FB0) relative to food intake, fecal output (“as is” basis), and fecal score, but feces were softer when dogs were fed the treatments (P = 0.031) and there was a linear increase (P = 0.011) in defecation frequency (stools/day) when FB increased in the diets. Dry matter, organic matter, and crude protein digestibilities were slightly higher when dogs were fed the control diet (P < 0.05) compared with the FB diets. All blood and serum chemistry parameters were similar among treatments and within the reference ranges. Dogs preferred the control diet relative to the 10% and 30% FB diets, but the 20% FB preference was similar to the control. Dogs remained healthy, maintained body weight and no adverse health events were observed during the study. Dehulled FB are a suitable ingredient for dog foods, but concentrations should not exceed 20% to avoid reduction in palatability and stool quality.

蚕豆作为狗粮中成分的评估：狗的脱皮蚕豆（Vicia faba L.）分级水平对挤压日粮的表观总消化率。

不断增长的宠物食品市场正在不断寻找新颖的成分。诸如蚕豆（FB）之类的豆类食品越来越受欢迎，并且已知对人体健康有益，但对于它们在宠物食品中的用途知之甚少。这项研究的目的是确定狗去皮FB利用的效果。实验饮食中添加了0％，10％，20％和30％的FB夹杂物（分别为FB0，FB10，FB20和FB30）。以重复的4×4拉丁方形设计，给小猎犬（n = 12）喂食9 d适应日粮，并收集5 d粪便。通过外部标记Cr ₂ O ₃确定表观总道消化率（ATTD）。在每个阶段的高潮期，从肱静脉穿刺术收集血液样本以进行全血细胞计数和血液化学分析。适口性通过2碗试验确定（n = 20）。借助统计软件（SAS v9.4），通过多元方差分析（MANOVA）分离出血液参数的平均值。计算了粪便参数和ATTD的对比度和最小二乘均值。显着性水平被认为是α= 0.05。狗吃掉所有提供的食物并保持体重。处理（FB10，FB20和FB30）与对照（FB0）之间在食物摄入，粪便排泄量（按现状）和粪便评分方面无差异（P > 0.05），但狗的粪便较软接受了治疗（P= 0.031），当日粮中FB增加时，排便频率（凳子/天）呈线性增加（P = 0.011）。与FB日粮相比，当给犬饲喂对照日粮时，干物质，有机物和粗蛋白消化率略高（P <0.05）。所有血液和血清化学参数在治疗之间和参考范围内均相似。相对于10％和30％的FB饮食，狗更喜欢对照饮食，但是20％的FB偏好与对照相似。在研究过程中，狗保持健康，保持体重并且没有观察到不良健康事件。去皮的FB是用于狗食的合适成分，但其​​浓度不应超过20％，以避免适口性和粪便质量下降。
