Assistant Laboratory Animal Technician (ALAT) Practice Exam

Temperature is the most significant factor affecting the thermal comfort of laboratory rodents because it directly influences their physiological state, behavior, and overall well-being. Rodents have a specific range of ambient temperatures in which they can maintain optimal body temperature. Outside of this range, they may experience stress, which can lead to a variety of adverse effects, including impaired immune function, altered metabolism, and changes in behavior.

While humidity levels, light conditions, and airflow can influence the comfort and health of rodents, temperature takes precedence as it fundamentally affects their thermoregulation. For instance, if the ambient temperature is too high or too low, it may result in overheating or hypothermia, respectively. Proper temperature management is crucial in laboratory settings to ensure the animals are kept in conditions that promote their welfare and facilitate accurate research outcomes.
