This template encodes a description of housing of animals, e.g., in home cages, holders for imaging, etc., over an interval during which environmental and handling conditions are relatively homogenous.
Only "static" parameters of the design and setup are recorded, and "nominal" values for environmental conditions such as humidity and temperature, but not "dynamic" parameters that might vary during one housing interval, and potentially be monitored, such as oxygen or ammonia levels, temperature, humidity, urine or fecal corticosterone levels, etc.
Values for product names and codes are expected to be accurate at the time the information is recorded, recognizing that products may evolve over time.

|
The type and identifier of the entire room in which, for example, one or more racks of housing units is located, not the housing unit itself. |
|
|
The manufacturer is expected to be the same for all housing unit components, rack, bottom and lid. |
|
|
The position in the rack is encoded as text since it may be an "identifier" or a description. It is not a set of numeric (e.g., row, column) or coded (e.g., top, bottom or middle) values, since there are too many possible arrangements. |
|
|
The number of animals usually applies to a single housing unit, but may also be used to describe the number of animals imaged simultaneously in a multi-animal imaging carrier or support device ("chamber", "holder", etc.). |
|
|
These may be internal or external dimensions, and are intended to provide an approximation of the living space and shape available. |
|
|
Description of measured or monitored or nominal values of temperature and humidity. The means of maintaining these conditions, if relevant, is described elsewhere (e.g., in the case of peri-procedural temperature control, in TID 8140 “Heating Conditions”). |
|
|
The bedding material may be described as a code or text, or both. The codes do not distinguish between methods of sterilization of the bedding material (e.g., irradiation, autoclaving or other heat treatment), since that is not a relevant factor for image interpretation. The definition of the NCIt concept is "that which comprises the place where a subject sleeps". |
|
|
The definition of the NCIt concept is "a replacement of the existing materials that make up the sleeping area of a subject", and is used here to specify the interval between bedding changes. |
|
|
The presence or absence of enrichment material is coded, but the type is not, and may be described as text, e.g., "facial tissue", "cotton (nesting material)". |
|
|
The presence or absence of an exercise device is coded, but the type is not, and may be described as text. |
