绵羊接受训练，使用操作性条件反射方法，其中它们用嘴按压面板以获得食物，以区分来自其他绵羊的各种排泄物或分泌物的气味。他们能够区分从2个不同个体收集的尿液样本对的气味，以及从不同绵羊收集的羊毛，粪便，唾液和指间袋，腹股沟袋和眶下袋的分泌物样本对的气味。在辨别任务中，绵羊面对2个反应面板，其中一个面板附近的一个管发出的气味用作正辨别刺激，另一个面板附近的另一个管发出的气味用作负辨别刺激。只有与正刺激相关的面板上的按压才会得到加强，并且两种气味同时出现。每次强化后，阳性气味的位置随机变化。在嗅球切除术后，绵羊无法进行辨别。
Sheep were trained, using an operant conditioning method in which they pressed panels with their muzzles in order to obtain food, to discriminate between odors from a variety of excretory or secretory products obtained from other sheep. They were able to discriminate between odors from pairs of urine samples collected from 2 different individuals, and also between odors from pairs of samples of wool, feces, saliva and the secretions from the interdigital pouch, the inguinal pouch and the infraorbital pouch collected from different sheep. In the discrimination task the sheep faced 2 response panels and a tube adjacent to one panel emitted the odor used as the positive discriminative stimulus and another tube near the other panel emitted the odor used as the negative discriminative stimulus. Only presses on the panel associated with the positive stimulus were reinforced and both odors were presented simultaneously. After each reinforcement the position of the positive odor was randomly varied. Following olfactory bulbectomy the sheep were unable to make the discriminations.
