Effect of LZ on intestinal immunity of weaned piglets. (A, B) Relative expression of inflammatory cytokine genes in jejunum and ileum (n = 6). TNF-α = tumor necrosis factor-α; IL-8/4/1β = interleukin-8/4/1β; IFN-γ = interferon-γ. (C, D) Relative expression of intestinal pathway protein genes in jejunum and ileum (n = 6). p38 MAPK = p38 mitogen-activated protein kinase; NF-κB p65 = nuclear factor-κB p65; IκBα = inhibitor of κB alpha; NF-κB = nuclear factor-k-gene binding; CON = control group; LZ = lysozyme group. Values are means ± SEM. Statistical differences in mean values of all indices were evaluated by independent t-test. The asterisk (∗) means P < 0.05.
