The amounts of specific substances needed per day that are generally thought to be nutritionally essential or conditionally important are similar among animal species when expressed per unit of energy consumed or per metabolic body size. Accordingly, a case is made that in addition to basal daily energy utilization, allometric scaling based on metabolic body size (3/4 power of mass or weight in kg) may be used to predict and compare basal nutrient requirements among widely varied species, as well as make comparative toxicological and other biological assessments and predictions. Furthermore, given the increasing evidence for allometric scaling for a broad range of biological phenomena (both empirical and theoretical) there is usually a good biological question to be answered when an organismal process deviates markedly from an allometric scale.
当按每消耗单位能量或每代谢体重来表示时，一般认为对营养而言必不可少或具有条件重要性的每日所需特定物质的量在动物物种之间是相似的。因此，有人提出，除了每日基础能量利用外，基于代谢体重（以千克为单位的质量或重量的3/4次方）的异速生长比例缩放可用于预测和比较广泛不同物种之间的基础营养需求，以及进行比较毒理学和其他生物学评估及预测。此外，鉴于越来越多的证据表明广泛的生物现象存在异速生长比例缩放（包括经验性和理论性证据），当一个机体过程明显偏离异速生长比例时，通常会有一个有待解答的良好生物学问题。
