The interaction of eating and drinking and the relation between intake and body weight was examined in pigeons maintained under laboratory conditions in order to obtain normative data on intake and weight regulation in this species. Under ad lib conditions food and water intake values are correlated, while deprivation of either nutrient leads to a reduction in the intake of the other. A linear relation between the log food intake and the log body weight was found under both ad lib and deprivation conditions. Following a period of food deprivation the pigeon shows both a short-term and a long-term compensatory increase in food intake whose magnitude is directly proportional to the degree of body weight loss produced by deprivation. The findings for the pigeon are similar in many respects to those reported for the rat and are discussed in relation to weight regulation and motivational mechanisms in hunger and thirst.
为了获取关于鸽子摄入量和体重调节的标准数据，对在实验室条件下饲养的鸽子的饮食交互作用以及摄入量与体重之间的关系进行了研究。在自由采食条件下，食物和水的摄入量值相关，而剥夺任何一种营养素都会导致另一种营养素摄入量的减少。在自由采食和剥夺条件下，均发现对数食物摄入量与对数体重之间存在线性关系。经过一段时间的食物剥夺后，鸽子的食物摄入量会出现短期和长期的代偿性增加，其幅度与剥夺导致的体重减轻程度成正比。鸽子的研究结果在许多方面与大鼠的研究结果相似，并结合饥饿和口渴时的体重调节及动机机制进行了讨论。
