Addition of P. pentosaceus YC induced the accumulation of gut propionate. A The levels of lactate in the intestinal contents; B The levels of acetate in the intestinal contents; C The levels of propionate in the intestinal contents; D and E The relative genes expression of ffar2 and ffar3 in PI and DI (n = 6). Data are represented as mean ± SEM. Asterisk refers to the significant difference (ANOVA with Tukey’s test; *P < 0.05, **P < 0.01). CON, control diet; GOS, gossypol diet; GP, gossypol diet supplemented with P. pentosaceus YC; ffar, free fatty acid receptor; PI, proximal intestine; DI, distal intestine
