The invention relates to a laboratory animal rearing cage with an air circulation function. The laboratory animal rearing cage comprises a box body and a box cover covering the box body, wherein the box cover is provided with an air inlet and an air outlet, the box cover is internally and fixedly connected with a partition plate, the partition plate is arranged in the axial directions of the air inlet and air outlet, the partition plate is arranged between the air inlet and the air outlet, the box cover is internally and horizontally provided with a baffle, the baffle is provided with multiplevent holes, the air inlet and the air outlet are formed between the baffle and the top wall of the box cover, the partition plate is perpendicular to the baffle, and the partition plate abuts againstthe baffle. According to the laboratory animal rearing cage with the air circulation function, in the testing process, the box body is connected with the box cover, when air change needs to be carried out on the inner portion of the box body, gas is introduced into the air inlet, and the gas can enter the box body and then is discharged from the air outlet, which can make the air flow in the boxbody fully exchanged and circulated and ensure the better gas flow effect in the box body, thereby being capable of making the survival state of animals in the box body better.
