Dietary level of potato protein concentrate and its effect on cytokine and volatile fatty acid intestinal concentration in weaned piglets.

Weaning is a traumatic event for the piglet, since it implies changes that are responsible for gastrointestinal disturbs, a productivity decreases or even death. Bacterial resistance development on account of sub-therapeutic doses of antibiotics inclusion in starter diets has become an important public health matter, banning their inclusion on animal feed. Potato protein concentrate (PPC) has been considered an alternative to regulate intestinal inflammation and gut disorders due to its content of antimicrobial peptides which have beneficial effects on gut homeostasis. This study evaluated the effect of the inclusion level of PPC in an antibiotic free diet on the inflammatory markers concentration as interleukin-12p40 (IL-12p40) and tumor necrosis factor alpha (TNF-() in ileal tissue and volatile fatty acid (VFA) concentration in colonic digesta. 90 piglets were assigned to three treatments: 1, basal diet (C) (diet without antibiotics nor PPC); 2, basal diet with 6% PPC (PPC 6%) and 3, basal diet with 8% PPC (PPC 8%). At 15 postweaning day, six piglets per treatment were euthanized for sample collection. The PPC 8% group had the highest levels of VFA and the lowest concentration of inflammatory cytokines compared to the C group which had the lowest levels of VFA and the highest concentration of inflammatory markers. The inclusion of PPC on the starter diets of weaned piglets can be an effective alternative to regulate the gut dysbiosis during weaning.
