Recent works have showed different interrelations between dietary tryptophan intake and aggressive behaviour in different groups of rats. In this experiment the AA. have treated thirty Sprague-Dawley rats (15 youngs and 15 adults) with tryptophan free-diet, during eight weeks. Muricide activity was weekly controlled; daily food intake for all group was recorded. Young rats feeding tryptophan free-diet and young rats pairfed controls showed aggressive behaviour at the sixth week of treatment. Adult rats did not show any changes of mouse killing during the whole period of experiment.
最近的研究表明，在不同组别的大鼠中，饮食中色氨酸的摄入量与攻击行为之间存在不同的相互关系。在本实验中，研究人员用无色氨酸饮食对30只斯普拉格-道利大鼠（15只幼年大鼠和15只成年大鼠）进行了为期八周的处理。每周监测杀鼠活性；记录所有组别的每日食物摄入量。食用无色氨酸饮食的幼年大鼠和配对喂养对照组的幼年大鼠在处理的第六周表现出攻击行为。成年大鼠在整个实验期间未表现出任何杀鼠行为的变化。
