This technology has three main components:
1. Detection of infrared radiation emitted by an object
2. Conversion of infrared radiation to temperature
3. Display of temperature distribution as an image
Cook cited several reasons for using IT to measure heat loss:
• Non-contact
• Automatable
• Non-invasive
• Sensitive to change
• Reflects metabolic activity
• Detects febrile responses
• Behavior can be measured from infrared images
However there are a number of factors can affect IT temperature:
• Reflected environmental infrared radiation
• Imprinted body heat
• Spatial distribution: The more animals that cluster together, the higher the ambient temperature recorded.
• Spatial distribution affects temperature
• Vaccination affects spatial distribution
• Vaccination induces an increase in radiated temperature
• In theory, only one pig needs to exhibit a febrile response to increase the maximum temperature recorded
