Abstract: This study was conducted to explore effects of Lonicerae flos and Rhomoma curcumae longae extracts (LR) on intestinal function of broilers. Three hundred broiler chickens were randomly assigned to the following 5 groups. The control group were fed the basal diet; the antibiotic group were fed the basal diet supplemented with spectinomycin hydrochloride (50 million units/ton) + lincomycin hydrochloride (25 g/ton); the LRH, LRM and LRL groups were fed the basal diet supplemented with a high dose (750 g/ton of feed), normal dose (500 g/ton of feed), or low dose (250 g/ton of feed) of LR, respectively. The changes of intestinal structure, intestinal digestive enzyme activities, antioxidant enzyme activities, inflammatory cytokines, and bacterial abundances in the colon and cecum contents were determined. The results indicated that compared with the control group and the antibiotic group, LR significantly increased the villus length/crypt depth (VCR) of the intestine, and significantly inhibited oxidative stress and inflammatory responses in the broiler intestine. In addition, LR regulated intestinal function by increasing the abundance of the intestinal microorganisms in broilers. In conclusion, LR improved antioxidant capacity, intestinal morphology, and microorganisms, and inhibited inflammatory response. The effect of high and medium doses of LR was better than lower doses.
