The Phenomaster is a versatile phenotyping system. Up to 16 animals are individually housed in standard cage bottoms, inside environmentally controlled chambers. The two environmentally controlled chambers can operate independently and control light intensity, temperature and humidity. The monitoring equipment around each cage simultaneously records food and drink consumption, body weight, activity, oxygen consumption and CO2 production. Implanted telemetry equipment can also be incorporated within the Phenomaster further expanding its capabilities as required. Indirect calorimetry for metabolic studies can be performed by using the measurement of O2 consumption and CO2 production. The monitoring equipment can also be programmed to automatically restrict access to food and to pair feed either single or groups of animals. Running wheels can similarly be programmed to operate freely or under restricted access.
