The objective of this study was to assess the effects of dietary supplementation with tannic acid (TA) on the growth performance, digestibility, antioxidant status, intestinal morphology and the caecal fermentation and microbiota in rabbits. A total number of 120 Ira rabbits (30 days of age) were randomly allotted to four dietary treatment groups: TA 0 (control), TA 0.75, TA 1.5 and TA 3, administered basal diets with 0, 0.75, 1.5 and 3 g TA/kg of feed for 28 days. Compared to the control group, dietary 3 g TA/kg inclusion decreased the average daily feed intake (p < 0.05). No significant differences were found in the digestibility among the groups (p > 0.05). Serum total antioxidant capacity was significantly higher in the 3 g/kg TA group than in the other groups (p < 0.05). There was a significant increase in the concentration of propionic acid and butyric acid in the 3 g/kg TA group. The addition of TA had no effect on villus height and crypt depth of small intestine (p > 0.05). The 16S rRNA high-throughput sequencing results showed that at the phylum level, dietary 3 g/kg TA increased the abundance of Bacteroidetes in the caecum of rabbits (p < 0.05). Based on the results, dietary TA is effective in antioxidant capacity of rabbits, improving caecal fermentation and optimizing the caecal microflora. However, the appropriate dosage supplementation of TA in rabbits needs further research.
