Description of the experimental design. Representation of the contact structure of the experiment (inoculated and direct-contact piglets in the pen on the left side of each room; indirect-contact piglets on the right side) for both MDA+ group (piglets having maternally-derived antibodies (MDAs); first column, rooms B1, B2 and B3) and MDA− group (piglets without MDAs; second column, rooms F1, F2 and F3). Control piglets (MDA+ and MDA−) are in room C1.
