1
Estimated using: floor space, m2 = k × (BW, kg)0.667, where k = 0.0336 (Gonyou et al., 2006).
2
Estimated using: feeder space = 1.1 × shoulder width (Brumm, 2012), and shoulder width, mm = 64.0 × (BW, kg)0.33 (Petherick, 1983).
3
Estimated using: right-angled waterer height, cm = 15 × (BW, kg)0.33 (Gonyou, 1996).
4
Estimated using: downward waterer height, cm = 18 × (BW, kg)0.33 (Gonyou, 1996).
5
Estimated using: heat production (W/kg) = 14.11 × (BW, kg)-0.38 (Brown-Brandt et al., 2004).
6
Assuming maximum truck load of 20,321.1 kg.
