Table 1 Weight of the study pigs at different timepoints during the study

Timepoint	Vaccinated pigs		Control pigs		Mean difference, kg (SE)*	P-value*
Timepoint	n	Weight in kg, average (SD)^#	n	Weight in kg, average (SD)^#	Mean difference, kg (SE)*	P-value*
Weaning	962	7.1 (1.2)	960	6.9 (1.2)	0.1 (0.4)	0.697
Delivery to finishing unit	861	24.1 (7.0)	923	22.9 (6.9)	1.2 (0.4)	0.002
Slaughter	800	103.9 (13.8)	800	100.3 (12.3)	3.6 (0.4)	< 0.001
