Dietary fiber describes a diverse assortment of nondigestible carbohydrates that play a vital role in the health of animals and maintenance of gastrointestinal tract homeostasis. The main roles dietary fiber play in the gastrointestinal tract include physically altering the digesta, modulating appetite and satiety, regulating digestion, and acting as a microbial energy source through fermentation. These functions can have widespread systemic effects. Fiber is a vital component of nearly all commercial canine and feline diets. Key features of fiber types, such as fermentability, solubility, and viscosity, have been shown to have clinical implications as well as health benefits in dogs and cats. Practitioners should know how to evaluate a diet for fiber content and the current knowledge on fiber supplementation as it relates to common enteropathies including acute diarrhea, chronic diarrhea, constipation, and hairball management. Understanding the fundamentals of dietary fiber allows the practicing clinician to use fiber optimally as a management modality.
膳食纤维描述了一大类不能消化的碳水化合物，它们在动物的健康和胃肠道内环境稳态的维持中起着至关重要的作用。膳食纤维在胃肠道中的主要作用包括物理改变消化物、调节食欲和饱腹感、调节消化以及通过发酵作为微生物的能量来源。这些功能可能会产生广泛的全身影响。纤维是几乎所有商业犬猫粮的重要组成部分。纤维类型的关键特性，如可发酵性、溶解度和粘性，已被证明在犬猫中具有临床意义和健康益处。从业者应该知道如何评估饮食中的纤维含量，以及与常见肠道疾病（包括急性腹泻、慢性腹泻、便秘和毛球管理）相关的纤维补充的最新知识。了解膳食纤维的基础知识可以使临床医生将纤维作为一种管理方式进行优化使用。
