The accurate estimation of the amount of energy contained within a food item which is available to a predator is essential in tests of optimal foraging theories. Many studies of optimal foraging measure gross energy content of prey directly by bomb calorimetry. I suggest that a more realistic and accurate estimate of true "prey value" is available by calculating energy associated with the organic constituents of prey, and then subtracting away energy associated with insoluble and indigestible components. This methodology allows for a much more precise estimate of prey value (useable energy) and therefore a more realistic test of optimal foraging models.
在最优觅食理论的测试中，准确估计捕食者可获取的食物所含能量至关重要。许多最优觅食研究通过弹式量热法直接测量猎物的总能量含量。我认为，通过计算与猎物有机成分相关的能量，然后减去与不溶性和不可消化成分相关的能量，可以更现实、准确地估计真正的“猎物价值”。这种方法能够更精确地估计猎物价值（可用能量），从而对最优觅食模型进行更现实的测试。
