1. 1.|In the cold, lambs behave as mature homeotherms from birth. 2. 2.|By 17 h post-partum the lower critical temperature had fallen by 8 deg. C due to (i) a 40% increase in minimal metabolic rate and (ii) the wet fleece drying out. 3. 3.|Smaller lambs were disadvantaged energetically having greater thermogenesis per unit of mass commencing at higher air temperatures.
