The apparent digestibilities of organic matter, protein, lipid and carbohydrate of a laboratory chow were determined in young adult female rats fed ad libitum, after losing 40-50% body weight and prolonging the loss for up to 15 weeks, and while recovering the lost body weight during a second period of ad libitum food intake. During deprivation the animals increased the apparent digestibility of crude protein but there was no significant change in digestibility coefficients of lipid or carbohydrate in relation to treatments. When food was again offered ad libitum to the deprived animals they ate large amounts compared with their body weights but normal amounts when compared with their age peers. Apparent crude protein digestibility immediately returned to pre-deprivation values. No impairment of ability to ingest and digest quantities of food relative to age was detected.
测定了实验室饲料中有机物、蛋白质、脂质和碳水化合物在自由采食的成年雌性幼鼠中的表观消化率。这些幼鼠体重减轻40%-50%并持续长达15周,随后在第二个自由采食期恢复体重。在禁食期间,动物提高了粗蛋白的表观消化率,但与处理方式相关的脂质或碳水化合物消化率系数没有显著变化。当再次向禁食动物自由提供食物时,与体重相比它们进食量很大,但与同龄动物相比则为正常量。粗蛋白表观消化率立即恢复到禁食前的值。未检测到相对于年龄而言摄取和消化食物量的能力受损。
