Rat/mouse sweet water preference experiment device and experiment method

Abstract

The invention discloses a rat / mouse sweet water preference experiment device and an experiment method, and relates to the technical field of animal science experiments and research devices. The rat / mouse sweet water preference experiment device comprises a mouse cage box body, a mouse cage cover, a water bottle placing frame, a water bottle, a water bottle knob, a plastic hose, a stainless steel pipe, a steel ball, a leaked water collector and a fixing support; a partition wall is arranged in the mouse cage box body, and the partition wall divides the mouse cage box body into a first containing chamber and a second containing chamber which are independent; and a drinking pipe and the leaked water collector are located in the second containing chamber, and an operation door is arranged on the wall face of the second containing chamber of the mouse cage box body. According to the rat / mouse sweet water preference experiment device, when the position of the water bottle needs to be exchanged in the experiment process, the water bottle does not need to be moved, only the position of the stainless steel pipe needs to be exchanged, measurement deviation caused by water leakage when the water bottle is moved can be avoided, and therefore experiment accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of animal science experiments and research devices, in particular to a device and an experimental method for experiments on sugar water preference of rats / mice. Background technique [0002] The sugar water preference test is a detection index used to evaluate whether the animal model of depression is anhedonia. Anhedonia refers to the lack of interest in rewarding stimuli, which is a manifestation of emotional disorders (including depression). An important evaluation index for the success of model building. [0003] In the sugar water preference experiment, single cage feeding is required, and two drinking bottles containing sugar water and pure water are given at the same time, and the positions of the water bottles are exchanged midway. Percent sucrose preference in mice. During the experiment, it is often necessary to eliminate various external interference factors to reduce the experimental error and ...

Problems solved by technology

[0009] The purpose of the present invention is to solve the technical problem that conventional cages cannot meet the experimental conditions during the sugar water preference experiment, and there is water leakage when exchanging the positions of the two water bottles. Experimental device and experimental method for rat / mice sugar water preference for experimental purposes
