Table 5.

Final selected linear mixed-effects model (M4) using the VNT titer in the piglets (n = 50) as continuous response variable, the age, VNT titer at birth, VNT titer of the sows, and strains as possible explanatory variables.

Random effects Variance SD
Piglet 0.01 0.10
Residual 0.04 0.20

Fixed effects Estimate SE t-Value

Intercept 0.2 0.07 2.8

Strain O Manisa −0.05 7 −0.8
Interaction age and strain A TUR/14/98 −0.002 0.002 −0.8
Interaction age and strain O Manisa 0.006 0.001 6.4
Interaction age and VNT titer at birth −0.005 0.001 −5.3

The piglet was included as random variable. Strain Asia-1 was the baseline variable.
