Dietary silybin supplementation alleviated liver injury induced by paraquat in piglets. (A) Representative H&E staining of liver tissues (captured at 100× or 400× magnification). (B) Histopathology scores of liver tissues. (C–E) Plasma activities of AST, ALT, and ALP. Ctrl, piglets were given a basal diet and were challenged with saline; Si, piglets were given a silybin-supplemented diet and were challenged with saline; PQ, piglets were given a basal diet and were challenged with paraquat; Si + PQ, piglets were given a silybin-supplemented diet and were challenged with paraquat; AST, aspartate transaminase; ALT, alanine transaminase; ALP, alkaline phosphatase. Data are expressed as mean ± standard error (n = 6). * p < 0.05.
