Tape-record presentation of anxious bleating activates the hypophysal-adrenal system in sheep adapted to experimental conditions. Stressory reaction of the hypophysal-adrenal system is characterized by an unusually long latency (no less than 3 hours) and long duration. The pattern of the observed reaction depends on experimental conditions: in sheep that after stimulation were held in group, activation of the hypophysal-adrenal complex was much shorter than in sheep kept in pairs.
对适应实验条件的绵羊播放焦虑咩叫的录音会激活垂体 - 肾上腺系统。垂体 - 肾上腺系统的应激反应具有异常长的潜伏期（不少于3小时）和持续时间长的特点。观察到的反应模式取决于实验条件：在刺激后成群饲养的绵羊中，垂体 - 肾上腺复合体的激活比成对饲养的绵羊短得多。
