Energy metabolism measurement research is not only an important topic in animal nutrition, genetic breeding, disease control and prevention, but also an important field of greenhouse gas emission research. According to statistics, the greenhouse gas produced by animal husbandry accounts for about 18% of global greenhouse gas emissions. The emissions of livestock greenhouse gases mainly include animal respiratory metabolism, ruminal fermentation of ruminants, and gas emissions formed during animal manure treatment. Ruminants have the highest greenhouse gas emissions. Taking methane (CH4) as an example, ruminant CH4 emissions account for 97% of global livestock CH4 emissions. Ruminants are one of the main sources of greenhouse gases, CH4 and carbon dioxide (CO2). Therefore, how to accurately monitor the gas emissions of ruminants and effectively slow down the greenhouse gas emissions of ruminants through breeding and breeding modes has become one of the main research topics.
1. Modular large animal respiratory metabolism measurement system:
Our medium and large animal respiratory metabolic measurement system can monitor the greenhouse gas emissions of ruminants such as cattle and sheep, including O2 consumption, CO2 emissions, CH4 emissions, and thus the animal's respiratory entropy and feed metabolism. Can wait.
The modular large animal respiratory metabolic measurement system uses indirect calorimetry to measure the caloric metabolism of an animal. It includes a gas analysis unit, an airflow generation control unit, and a data acquisition and analysis unit, which can be configured according to different subjects and research contents. Different measurement systems.
1. The system includes CO2 analyzer, O2 analyzer, CH4 analyzer, H2O analyzer
2. According to the size of the animal, different types of Flowkit gas generation control systems can be selected, such as Flowkit100 (gas flux up to 100L/min, suitable for measurement of respiratory metabolism of medium-sized animals such as large poultry), Flowkit500 (gas flux up to 500L/min), Flowkit1000 (gas flux up to 1000L/min), Flowkit2000 (gas flux up to 2000L/min, suitable for respiratory metabolism measurement of large animals such as cattle)
3. Optional single-channel, multi-channel measurement system (the picture below shows multi-channel large poultry respiratory metabolism configuration)

Second, portable large animal respiratory metabolism measurement system:
The FMS is equipped with a high-precision CO2 analyzer, O2 analyzer, water vapor analyzer, Baseline unit, gas sub-sampling unit and data acquisition system; Foxbox is an ultra-portable animal breathing and energy metabolism measurement system equipped with CO2 and O2 analyzers. , gas sampling unit and data acquisition system. FMS or Foxbox can be easily brought to the field for field experiments, or a more complex multi-channel system can be formed in the laboratory to achieve rapid measurement of medium and large animals.
The system is highly portable and highly integrated, and can be used for energy metabolism measurement in large outdoor animals, in the cabin, and in the laboratory.

Third, ruminant behavior monitoring and measurement system
The configuration of the ruminant behavior monitoring and measurement system is mainly composed of an activity data recorder, a cage, and analysis software. Sensors and data loggers are integrated into the cage to monitor eating and rumbling behavior.

In addition to monitoring the feeding and ruminating behavior of ruminants, the system can also calculate the total ruminating (feeding) time and duration and derive a time distribution map.
Fourth, DST implanted medium and large animal body temperature and heart rate recorder
DST series implantable animal temperature and heart rate recorders are available in different models such as Nano, Micro, Milli and Centi, which can be used for body temperature and heart rate monitoring of different sizes of animals such as Mus musculus, mouse, monkey, sheep and cattle. The Centi series is targeted at medium and large animals such as cattle and sheep. Its body temperature Centi-T implant can last for 9 years, and its body temperature heart rate Centi-HRT implant can work for 19 months, meeting various conditions. The monitoring of body temperature and heart rate of large and medium-sized animals such as cattle and sheep is widely used in experimental animal monitoring, animal physiological and ecological research, pharmacological research, pathological research, toxicity experiment, immunological research experiment, energy metabolism measurement and monitoring.
Five, infrared thermal imaging measurement system
The infrared thermal imager consists of a calibrated high-sensitivity infrared thermal imaging sensor, optical lens and analysis software. It can be directly connected to the computer for analysis by USB3 interface (very suitable for laboratory use and PCB analysis), and optional GigE network interface. Conduct network monitoring. The instrument is designed with high resolution, high precision, high sensitivity and high sensitivity (30mK). It can be used for thermal imaging of animals in different environments such as laboratories and farms, and accurate non-contact measurement to monitor temperature and temperature changes in time and space. It is widely used in life. Science such as animal energy metabolism research, disease diagnosis, farm monitoring and management, etc. (right picture shows calf infrared thermal imaging of infected foot-and-mouth disease).
