摘　　要：本文报道了不同环境温度和食物种类对一龄乌龟和二龄乌龟生长率、摄食量、消化率以及食物消化时间的影响。结果表明:随温度升高 (20℃→30℃),幼龟生长率、摄食量逐渐增加;一龄乌龟消化率随温度升高逐渐降低;但二龄乌龟的消化率在各温级间基本保持一致。食物消化时间与温度呈直线负相关。温度、食物种类和动物大小对幼龟食物脂肪消化率影响不显著。食物种类和动物大小对生长率、消化率的影响程度随温度而变,但对食物消化时间没有显著影响。In this paper, we reported the effect of ambient temperature (T) and kinds of food on growth rate, food intake, digestive efficiency and passage time ( PT) in the one-year-old and two-year-old juvenile turtles, Chinemys reevesii. The turtles refused to take food when T was below 15℃. In the range of experimental T, growth rate, average daily food intake were positively correlated with T. Digestive efficiency of energy (DEE) of the one-year-old turtles decreased gradully as T rised, but the DEE of the two -year-old turtles did not vary significantly. The PT was negatively correlated with T. The T, kinds of food and size of the turtles did not affect on the digestive efficiency of lipid (DEL) significantly. The degree of effect of kinds of food and the size of the turtles on the growth rate and DEE depended on the T, but they did not affect on PT significantly.
