Figure 1

Diagram showing the experimental design and the pig allocation for each group. A Distribution of pigs in each treatment group. Pigs from different treatment groups are shown with disparate colors. The total number of pigs distributed in each treatment group (n) is indicated below the pig icons. B Distribution of vaccinated and seeder pigs in each room. Colors representing pigs from different treatment groups correspond to colors used in A. Top panel indicates distribution of whole inactivated vaccine groups and bottom panel indicates the distribution of live attenuated vaccine groups. The total number of rooms used for housing pigs which received the whole inactivate or live attenuate vaccine administration (*) are also indicated. The six pigs from control group NO VAC/NO CHA were housed in a separate single room which is not shown in this figure.
