¹ Sprinkling methods, applied by researchers were: Control (no water sprinkled and bedding dry; not applied in HOT weather), bedding only (bedding already being damp or wetted for 4–6 min before the start of loading), pigs only (pigs being wetted after loading completed for 6–8 min when the bedding was dry), pigs and bedding (both pigs and bedding being watered).

² Transport losses were non-ambulatory (sum of fatigued and injured pigs), dead (sum of euthanized- and dead on arrival), and total transport losses (sum of non-ambulatory and dead).

³ WARM weather was defined as the temperature <26.7 °C; based on 79 loads.

⁴ HOT weather was defined as the temperature ≥26.7 °C; based on 49 loads.
