Water intake (drinking water and water from food) and urinary output in rhesus (Macaca mulatta) and cynomolgus monkey (M. fascicularis) watered ad libitum in individual cage were examined with 52 animals. The animal room was maintained at 25 +/- 2 degrees C and 55 +/- 10% with relative humidity, being lit at 12 hours interval. Water intake was found in wide variation between individuals, and about 20% of the monkeys were recognized as polydipsia without another abnormal behavior. No significant variation was found between daily water intake, but periodical (or seasonal) variation was observed in polydipsic monkey. Urinary output changed accordingly with water intake. Rate of the urinary output to the water intake was 76% in male rhesus, 59% in male cynomolgus and 49% in female cynomolgus. The rate was higher in the polydipsia than in the normal monkey. Diurnal patterns of water drinking and urinary output indicated that the monkeys were mostly active during the hours of lighting. Some effects of experimental procedure were observed on drinking and voiding in cynomolgus monkeys while no effect on rhesus monkeys. Prandial drinking was observed in monkeys as was reported on other laboratory animals such as rats.
对52只恒河猴（猕猴属）和食蟹猴（食蟹猕猴）进行了研究，这些猴子被单独关在笼子里，可随意饮水，观察它们的水摄入量（饮用水和食物中的水）和尿量。动物房温度保持在25±2摄氏度，相对湿度为55±10%，每隔12小时照明一次。发现个体间的水摄入量差异很大，约20%的猴子被认定为烦渴但无其他异常行为。每日水摄入量之间未发现显著差异，但在烦渴的猴子中观察到周期性（或季节性）变化。尿量随水摄入量相应变化。雄性恒河猴的尿量与水摄入量的比率为76%，雄性食蟹猴为59%，雌性食蟹猴为49%。烦渴猴子的该比率高于正常猴子。饮水和排尿的昼夜模式表明，猴子在光照时间大多活跃。在食蟹猴身上观察到实验过程对饮水和排尿有一些影响，而对恒河猴没有影响。正如在大鼠等其他实验动物上所报道的那样，在猴子身上也观察到了进餐时饮水的情况。
