To determine the prevalence of nutrients less than or greater than accepted standards in commercially available enteral diets for cats, and to identify contamination incidence in enteral diets for cats.
Prospective cross-sectional study.
University teaching hospital.
Seven commercial enteral diets for cats.
Labels were evaluated to determine if diets were intended to be nutritionally complete and balanced. One diet under storage techniques partially representative of clinical conditions was sampled on days 0, 1, 3, 5, and 7 of storage for aerobic bacterial culture.
All 7 diets were analyzed for key nutrients and results were compared to Association of American Feed Control Officials (AAFCO) Nutrient Profiles for Adult Cats for maintenance and National Research Council recommended allowance (NRC-RA). From label information, 4 diets were classified as complete and balanced and 3 diets were classified as not complete and balanced. All 7 diets had at least 1 nutrient less than the AAFCO minimums and the NRC-RA. The total number of nutrients less than AAFCO minimums ranged from 3 to 9 (median = 4), with iron, potassium, and manganese being the most common. Concentrations of some nutrients were undetectable. None of the samples tested had a positive aerobic culture at baseline (day 0) or on subsequent samples from days 1, 3, 5, and 7 under any storage condition.
None of the diets analyzed met all of the minimum nutrient concentrations. While short-term feeding may not be of concern for an individual patient, clinicians should be aware of potential nutritional limitations when feeding enteral diets to ill or injured cats.
确定市售猫用肠内营养制剂中低于或高于公认标准的营养素的流行情况，并确定猫用肠内营养制剂的污染发生率。
前瞻性横断面研究。
大学教学医院。
七种市售猫用肠内营养制剂。
评估产品标签，以确定营养制剂是否旨在提供营养全面且均衡的饮食。在储存0、1、3、5和7天时，对一种采用部分代表临床条件的储存技术的营养制剂进行取样，以进行需氧细菌培养。
对所有7种营养制剂进行关键营养素分析，并将结果与美国饲料管理官员协会（AAFCO）成年猫维持期营养成分表以及美国国家研究委员会推荐摄入量（NRC-RA）进行比较。根据标签信息，4种营养制剂被归类为营养全面且均衡，3种营养制剂被归类为营养不全面且不均衡。所有7种营养制剂中至少有一种营养素低于AAFCO最低标准和NRC-RA。低于AAFCO最低标准的营养素总数在3至9种之间（中位数 = 4），其中铁、钾和锰最为常见。部分营养素的浓度无法检测到。在任何储存条件下，所有测试样本在基线期（第0天）或第1、3、5和7天的后续样本中均未出现需氧菌培养阳性结果。
所分析的营养制剂均未达到所有最低营养素浓度标准。虽然短期喂食可能对个体患者而言并无大碍，但临床医生在给患病或受伤的猫喂食肠内营养制剂时，应意识到潜在的营养限制。
