¹Sows were fed yeast culture (XPC, Diamond V, Cedar Rapids, IA, USA) from day 90 of gestation to day 21 of lactation.

²CON = sows fed control diet; XPC = sows fed diet supplemented with 2.0 g/kg XPC. Piglets were weaned at 21 d of age and slaughtered 4 h after lipopolysaccharide (LPS) injection on the day of weaning.

³IL-1β, interleukin-1β; IL-6, interleukin-6; IL-10, interleukin-10; TNF-α, tumor necrosis factor-α. Data are means ± standard errors of six piglets per treatment.
