¹Results of the mixed multivariable linear regression model BW1.

²Timepoints included T1 (arrival), and T2 (~3 to 4 d [78 to 93 h] after arrival), as T0 (before transport) weight was included as a covariate. Five piglet weights were not recorded for the fourth short duration transport event at T1.
