A novel forced-air ventilation system for rodent cages was developed. The apparatus was operated at an air flow rate of 56 L/min when used with a 230 mm wide X 450 mm long X 165 mm deep cage. Air velocity measurements in the cage did not exceed 8 m/min at animal (rat) height. The average NH3 concentration in a cage which housed two 250 g rats was less than 0.3 ppm at the end of the third day, whereas the concentration measured in a cage without the forced-air ventilation system was 150 ppm after 3 days. Tests of the water content of soiled bedding showed the forced-air ventilation system to provide a much drier environment for the rodents.
开发了一种用于啮齿动物笼的新型强制通风系统。当与一个宽230毫米、长450毫米、深165毫米的笼子一起使用时，该装置以56升/分钟的气流速率运行。在动物（大鼠）高度处，笼内的空气流速测量值不超过8米/分钟。在第三天结束时，饲养两只250克大鼠的笼子中的平均氨浓度低于0.3 ppm，而在没有强制通风系统的笼子中，3天后测得的浓度为150 ppm。对脏垫料含水量的测试表明，强制通风系统为啮齿动物提供了一个干燥得多的环境。
