We evaluated the nutritional adequacy of 2 dry-type commercially prepared dog diets by use of a gestation/lactation/growth protocol outlined by the Association of American Feed Control Officials. Both diets were formulated to contain minimal concentrations of nutrients, compared with canine nutrient requirements listed in the 1974 or 1985 National Research Council publications. Although there were no significant differences in the performance of dogs fed either diet, only one of the diets (diet 2) passed the complete life-stage protocol test. The nutritional profile of diet 1 was only sufficient to support a claim of complete and balanced nutrition for adult maintenance. Any commercial dry dog food meeting the nutrient levels in diet 2, and of similar nutrient bioavailability, should also pass an Association of American Feed Control Officials complete life-stage protocol test.
我们按照美国饲料管理官员协会概述的妊娠/泌乳/生长方案，评估了两种市售干式犬粮的营养充足性。与1974年或1985年美国国家研究委员会出版物中列出的犬类营养需求相比，两种犬粮的营养成分含量均设定为最低。尽管喂食这两种犬粮的犬只表现没有显著差异，但只有其中一种犬粮（犬粮2）通过了完整生命阶段方案测试。犬粮1的营养成分仅足以支持其对成年犬维持期完全均衡营养的宣称。任何符合犬粮2营养水平且具有相似营养生物利用率的市售干式犬粮，也应能通过美国饲料管理官员协会的完整生命阶段方案测试。
