Higher contents of SCFAs increase FFARs and GLP-1R expression in the intestine of both PB and GG groups at 21 days of age. (A) SCFAs in the cecum contents (mmol/kg wet weight) of chickens in control, PB and GG groups at 21 days of age (n = 10 in control and PB groups; n = 8 in GG group); (B–D) effect of probiotics and guar gum on mRNA expression levels of FFAR2 (B), FFAR3 (C), and GLP-1R (D) in the intestine of chickens at 21 days of age (n = 8). Data were presented as Mean ± SE, ∗p < 0.05 and ∗∗p < 0.01.
