What temperature range is commonly used in many facilities as stated in the material?

• A. 59 to 64 ˚F
• B. 64 to 69 ˚F
• C. 70 to 76 ˚F
• D. 77 to 84 ˚F

Answer: (C)

Temperature in animal housing is kept within a comfortable room-temperature range to support both animal welfare and practical operations. The material notes that many facilities commonly use about 70 to 76 °F as the ambient housing temperature. This range strikes a balance by reducing cold stress for animals—who can be sensitive to cooler room temperatures—without introducing heat stress that can occur at higher temperatures. Cooler options can slow metabolism and potentially affect experimental outcomes, while warmer options can lead to dehydration and stress, influencing behavior and physiology. By choosing roughly 70–76 °F, facilities aim to maintain a stable, humane environment that works well across a variety of standard lab conditions.
