Oleanolic acid improves antioxidant capacity and the abundance of Faecalibacterium prausnitzii in the intestine of broilers.

ABSTRACT: This study investigated the effect of dietary oleanolic acid (OA) addition on broiler intestinal morphology, intestinal antioxidant capacity, changes in cecum microbiota, and the relationship between microbiota and antioxidant capacity. A total of 288 Arbor Acres broilers at 1-day-old broilers were reared, and they were randomly divided into four groups. The control and experimental groups were fed the basal diet and the basal diet supplemented with 50, 100, and 150 mg/kg OA for a total of 42 d respectively. The results showed that OA does not affect the performance of broiler chickens. The OA supplementation increased the ratio between jejunum villus height and crypt depth (P < 0.05). The expression of antioxidant enzymes (GSH-PX and CAT) and antioxidant-related genes (HO-1, NQO1, Nrf2, a
