The core of animal metabolism research equipment is to track oxygen consumption and carbon dioxide production. Based on the law of conservation of energy, high-precision sensors are used to collect real-time data and calculate the level of energy metabolism. For example, in a closed or semi open metabolic cage, the system can accurately record the volume changes of O2 inhaled and CO2 exhaled by animals per unit time, thereby calculating respiratory quotient and basal metabolic rate.

The system uses indirect calorimetry technology, combined with the principle of heat conduction, to measure the heat emitted from the animal's body surface. Simultaneously integrating parameters such as dietary intake and activity level, constructing a comprehensive energy balance model to achieve multidimensional data analysis. Support multi-channel synchronous monitoring, which can record behavioral indicators such as food intake, water intake, and movement trajectory of animals in an unconstrained state. By using algorithms to spatially and temporally correlate these dynamic behaviors with metabolic data, we can reveal the mechanisms by which different physiological states affect metabolism. Relying on an intelligent control system, the equipment can automatically complete processes such as gas sampling, filtration and dehumidification, and component analysis. Cooperating with specialized software to achieve real-time data statistics and visual display effectively avoids the problem of error accumulation caused by traditional manual operations.

Precautions for using animal metabolism research equipment:

1. Environmental stability control

-Maintaining a constant room temperature to eliminate the impact of temperature fluctuations on metabolic rate, especially in circadian rhythm research, this principle must be strictly followed.

-Control the noise level below 50dB and lay soft padding inside the cage to alleviate animal anxiety, thereby reducing the interference of stress hormone secretion on the results.

2. Animal welfare protection measures

-Single experiment duration limit: In principle, it should not exceed 48 hours. During long-term follow-up, reasonable rest intervals should be set to avoid chronic stress accumulation.

-Standardized operation training: All personnel who come into contact with animals must receive sterile techniques and painless operation guidance to reduce human stimulation sources.

3. Equipment maintenance and quality control standards

-Regular deep cleaning: Implement periodic disinfection procedures for metabolic chambers, respiratory circuits, and sensor probes to prevent microbial growth from blocking airflow channels.

-Performance verification test: Conduct a cross range linearity test once a month to ensure consistency in detection sensitivity within high and low concentration ranges.

4. Suggestions for optimizing experimental design

-Parallel control setting: Conduct horizontal comparisons between animals with the same genetic background to improve statistical effectiveness; If necessary, introduce a sham surgery group as a negative control.
