Natural compounds derived from plants have gained a considerable interest as diet additives for the potential to improve animal health and performance. This study focused on the eﬀects of the dietary administration of Passiﬂora incarnata extract on skin lesion, thermal imaging and immunity in weaned piglets. Growth performances were also monitored. Eighty piglets weaned at 28 days of age, with a mean starting weight of 10.0 ± 0.43 kg were randomly assigned to one of two dietary treatments: control diet (CON) and CON diet supplemented with 1 kg/t of Passiﬂora incarnata (PASS). The results showed that the group fed with a diet supplementedwithPassiﬂoraincarnatawascharacterizedbyequalgrowthperformanceofthecontroldietgroup, less body lesions (P < 0.01), higher ear and back temperature (P < 0.01) and activated immune response. Time eﬀect was observed for body lesion (P < 0.01), thermal imaging (P < 0.01), and for IL-4, IL-6, IL-8 and TNF−α (P < 0.05). Compared with female, male piglets had higher levels of IL-1β, IL-8, TNF-α and NF-κB. In conclusion this study conﬁrmed that Passiﬂora extract orally administered provides calming eﬀect without altering growth performance.
