Playing behaviour of piglets during the experiment. Playing behaviour of piglets was measured in the intravenously infected piglets (panel a) and the intranasally infected piglets (panel b) using a pedometer attached to a hanging chain. Read out gives an estimation of playing behaviour for the whole group of piglets. Red line indicates the moment of infection. ● solid line indicates piglets infected with the high dose; ○ dashed line indicates piglets infected with the low dose
