Standing \({\dot{\text{V}}\text{O}}_{2}\) at rest measured in this study at different temperatures and accounting for DBA 0–1.22 y = 66.95 + 0.15Ta2 + − 7.97Ta + W + A
Resting Lying down has been measured to use 29% less energy than standing for goats (Dailey and Hobbs, 1989) 0–0.434 y = (66.95 + 0.15Ta2 + − 7.97Ta + W + A) *0.29

Walking Walking \({\dot{\text{V}}\text{O}}_{2}\) measured in this study at different speeds and terrain slopes at equivalent DBA 0.105–0.786 y = − 75.622 + αj + (642.345 + γi) *A + Ta + W
