IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

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.
