The Effect of Ambient Temperature and Kinds of Food on Growth and Digestion of Juvenile Turtles,Chinemys reevesll

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 or the turtles on the growth rate and DEE depended on the T,but they did not affect on PT significantly.
