Fig. 2From: Sodium butyrate improves antioxidant stability in sub-acute ruminal acidosis in dairy goatsEffect of sodium butyrate on LPS concentration in the rumen, portal vein, hepatic vein and jugular vein plasma of dairy goats fed three diets (LG, HG and HG + NaB). a Ruminal LPS, b Portal vein LPS, c Hepatic vein LPS. The concentration of lipopolysaccharide (LPS) in plasma was determined by a chromogenic endpoint limulus amoebocyte lysate assay kit (CE64406 &CE80545, Chinese Horseshoe Crab Reagent Manufactory Co., Ltd., Xiamen, China). Data were analysed by mixed model in SAS (SAS version 9.2, SAS Institute Inc., USA) and are expressed as the mean ± S.E.M. **P < 0.01, * P < 0.05. LG = low grain; HG = high grain; HG + NaB = high grain + sodium butyrateBack to article page
