Effect of dietary tea polyphenols on growth performance and cell-mediated immune response of post-weaning piglets under oxidative stress



Effect of dietary tea polyphenols on growth performance and cell-mediated immune response of post-weaning piglets under oxidative stress



Archives of Animal Nutrition 64(1): 12-21



To gain insights into the effects of tea polyphenols (TP) on growth performance and cell-mediated immune response of piglets under oxidative stress, an oxidative stress model was established by intraperitoneally injecting weaned piglets with diquat. After intake of either basal diet or TP-supplemented diet for 7 d, half of the piglets in each group were challenged with diquat. Results showed that dietary TP alleviated growth depression to some extent. A T lymphocyte transformation test (LTT) demonstrated that TP promoted the proliferation and activation of T lymphocytes. The ratio of CD4+/CD8+ was elevated, indicating a recovering tendency from immune damages caused by oxidative stress. The increment of pro-inflammatory IL-1 caused by oxidative stress was attenuated, and the concentration of serum IFN-gamma was decreased by TP-supplementation. However, the serum concentrations of anti-inflammatory cytokine, such as IL-4, were greatly enhanced by TP, which suggested an immune shift from Th1 to Th2. These findings supported the immunomodulatory potential of TP for piglets subjected to oxidative stress.
