Body water content and total body water turnover in cats fed commercially available dry food and then given canned rations were determined with tritiated water. Cats during the feeding of either ration did not differ in body water content or turnover. Cats during the feeding of the dry ration derived a greater fraction of their total water turnover from drinking water, and these cats drank more water per gram of dry matter intake than when fed the canned ration. On the basis of total water intake, however, those given the canned ration had significantly greater water intake per gram of dry matter; also, their total water turnover per gram of dry matter was greater. Compared with other animals, cats have a similar ratio of body water to body solids, but the rate of water turnover per unit of body weight is slower.
用氚标记水测定了食用市售干粮后改喂罐头食品的猫的身体含水量和全身水周转率。在喂食任何一种日粮期间,猫的身体含水量或周转率没有差异。在喂食干粮期间,猫的总水周转率中来自饮用水的比例更大,并且这些猫每摄入一克干物质所喝的水比喂食罐头食品时更多。然而,基于总水摄入量,喂食罐头食品的猫每克干物质的水摄入量显著更高;此外,它们每克干物质的总水周转率也更高。与其他动物相比,猫的身体水分与身体固体的比例相似,但单位体重的水周转率较慢。
