Ruminant with Highest BMR and Body Temperature

Correct Answer: Goat

Among domesticated ruminants, the goat has the highest BMR and the highest normal body temperature (~39.5°C).

Normal Body Temperatures

• Cattle: 38.5°C
• Buffalo: 38.5°C
• Sheep: 39°C
• Goat: 39.5°C — highest

Metabolic Body Weight

BMR is expressed relative to metabolic body weight = W⁰·⁷⁵. Goats have relatively higher metabolic activity per unit metabolic body weight due to their active lifestyle and higher surface area-to-volume ratio.
