Dog foods with similar claims for nutritional adequacy were tested by chemical analysis and the American Association of Feed Control Officials' growth trial. All foods tested were similar chemically, however, dogs given one regionally marketed food had lower growth rate and food efficiency as well as suboptimal PCV and hemoglobin values during the growth trial. Pups fed this diet also had clinical signs typical of zinc and copper deficiencies. We concluded that American Association of Feed Control Officials' approved feeding tests provide valid assessment of pet food quality, and procedures involving only chemical analysis or calculated values may not.
通过化学分析和美国饲料管理官员协会的生长试验，对具有类似营养充足性声明的狗粮进行了测试。所有测试的狗粮在化学成分上相似，然而，在生长试验期间，食用一种在当地销售的狗粮的狗生长速度较慢、食物效率较低，且红细胞压积和血红蛋白值未达最佳水平。食用这种日粮的幼犬还出现了典型的锌和铜缺乏临床症状。我们得出结论，美国饲料管理官员协会批准的喂养试验能有效评估宠物食品质量，而仅涉及化学分析或计算值的程序可能无法做到。
