Two groups of young growing dogs (one group maintained on balanced commercial diet and the other on high-fat-low-calcium diet) and one group of adults dogs on balanced commercial diet were given lead orally at 4 different dose levels. Post-treatment blood lead levels did not reveal any significant difference between the young and adult dogs maintained on balanced commercial diet. However, dogs on the high-fat-low-calcium diet showed marked elevation in blood lead at each of the 4 dose levels used. The results emphasise the importance of dietary factors in absorption of lead from the alimentary tract and suggest that the influence of age on lead uptake from the gut requires further evaluation.
两组幼犬（一组喂食均衡的商业饮食，另一组喂食高脂肪低钙饮食）和一组成年犬喂食均衡的商业饮食，分别给予4种不同剂量水平的铅。治疗后，喂食均衡商业饮食的幼犬和成年犬的血铅水平没有显示出任何显著差异。然而，喂食高脂肪低钙饮食的犬在使用的4个剂量水平下，血铅均显著升高。结果强调了饮食因素在肠道吸收铅中的重要性，并表明年龄对肠道吸收铅的影响需要进一步评估。
