In order to enhance the health and welfare of obese dogs and to facilitate the required loss of body weight, commercial diets are produced with fibrous ingredients. Cellulose is a common dietary fiber used mainly in powdered form. However, other processing forms and fibers are available as fibrous additives. This work aimed to test the effects of different fiber sources on apparent total tract digestibility and fecal quality in dogs. Four diets were fed to eight dogs (experimental design: 4 × 4 Latin square) for a 14-day period each. In addition to a basal diet (CO), three experimental diets varying in fiber sources were used: powdered cellulose (CE), granulated cellulose (GC), and lignocellulose (LC). Dogs fed the CO had lower crude fiber digestibility than those fed the other experimental diets ( < 0.0033). Dogs fed diets supplemented with fiber sources had lower gross energy digestibility (range: 76.2-77.3%) compared with those fed the CO (84.4%). In all groups, the fecal score (consistency and shape) ranged within the optimal values; solely wet fecal output was increased for the fiber groups compared with those on the CO. This study demonstrated that various sources of fiber such as GC and LC can be used as alternatives to CE without restrictions.
为提高肥胖犬的健康水平和福利，并促进其体重的必要减轻，人们生产了含有纤维成分的商业犬粮。纤维素是一种常见的膳食纤维，主要以粉末形式使用。然而，其他加工形式和纤维也可作为纤维添加剂使用。这项工作旨在测试不同纤维来源对犬类表观全肠道消化率和粪便质量的影响。给八只犬喂食四种犬粮（实验设计：4×4拉丁方），每种犬粮喂食14天。除基础犬粮（CO）外，还使用了三种纤维来源不同的实验犬粮：粉末状纤维素（CE）、颗粒状纤维素（GC）和木质纤维素（LC）。喂食CO的犬的粗纤维消化率低于喂食其他实验犬粮的犬（<0.0033）。与喂食CO的犬（84.4%）相比，喂食添加了纤维来源犬粮的犬的总能消化率较低（范围：76.2 - 77.3%）。在所有组中，粪便评分（稠度和形状）均在最佳值范围内；与喂食CO的犬相比，纤维组仅湿粪便产量增加。本研究表明，各种纤维来源，如GC和LC，可不受限制地用作CE的替代品。
