The role of legume and oil seeds in animal nutrition could be more important if negative effects of so-called antinutritional factors (ANFs) could be adequately eliminated. Processing standards to attain an optimum nutritional value will then have to be based on the nutritional evaluation of legume and oil seeds. Priorities in studying the effects of processing these raw materials are to attain an optimum degree of nutritional value of protein rather than the reduction of ANFs. Obviously, reduction of proteinaceous ANFs can be accomplished by thermal methods of treatment. Residual activities of the ANFs alone, however, do not predict the quality of protein in vivo, in every case. Other factors (storage protein, carbohydrates) may also be important in addition to ANFs. This means that elimination of ANFs alone however, cannot always ensure a sufficient increase in digestibility as determined in experimental studies in animals. By correlating the results of technological experiments with those of trials in animals, optimum information may be gathered in attempting to attain an optimum nutritional value by technological methods of treatment. This will contribute to a more correct and accurate understanding of the effects of animal feed technology on the performance of animals and the consequences for the excretion of undigested nutrients in the environment.
如果所谓的抗营养因子（ANFs）的负面影响能够得到充分消除，豆类和油籽在动物营养中的作用可能会更加重要。要达到最佳营养价值的加工标准，将必须基于对豆类和油籽的营养评估。研究这些原材料加工效果的重点是实现蛋白质营养价值的最佳程度，而不是减少抗营养因子。显然，蛋白质类抗营养因子的减少可以通过热处理方法来实现。然而，仅抗营养因子的残留活性并不能在每种情况下预测体内蛋白质的质量。除了抗营养因子之外，其他因素（储存蛋白、碳水化合物）可能也很重要。这意味着，仅消除抗营养因子并不能总是确保在动物实验研究中确定的消化率有足够的提高。通过将技术实验结果与动物试验结果相关联，在试图通过技术处理方法达到最佳营养价值时，可能会收集到最佳信息。这将有助于更正确和准确地理解动物饲料技术对动物性能的影响以及对环境中未消化养分排泄的后果。
