Final selected linear model (M2) using the VNT titer at birth of the piglets (n = 50) as continuous response variable, the VNT titer of the dam and strains as possible explanatory variables.

	Estimate	SE	t-Value	p-Value
Intercept	0.6	0.1	5.5	≪0.001
VNT titer of dam	1.6	0.2	8.3	≪0.001
Strain A TUR/14/98	1.3	0.6	2.2	0.03
Strain O Manisa	0.6	0.2	3.5	0.0006

Interaction VNT titer dam and strain O Manisa	−0.7	0.2	3.2	0.001

Strain Asia-1 was the baseline variable.
