To explore the effect of coated tannin (CT) on the growth performance, nutrients digestibility, and intestinal function in weaned piglets, a total of 180 piglets Duroc × Landrace × Yorkshire (28 d old) weighing about 8.6 kg were randomly allotted to three treatments: 1) Con: basal diet (contains ZnSO4); 2) Tan: basal diet + 0.15% CT; and 3) ZnO: basal diet + ZnO (Zn content is 1,600 mg/kg). The results showed that 0.15% CT could highly increase the average daily gain and average daily feed intake of weaned piglets compared with the control group, especially decreasing diarrhea incidence significantly (P < 0.05). Compared with the control group, crude protein apparent digestibility and digestive enzyme activity of the piglets fed with 0.15% CT were enhanced obviously (P < 0.05). Meanwhile, the intestinal villi and microvilli arranged more densely, while the content of serum diamine oxidase was decreased, and the protein expressions of zonula occludens-1 (ZO-1) and claudin-1 were significantly upregulated (P < 0.05). In addition, CT altered the structure of intestinal microbiota and augmented some butyrate-producing bacteria such as Ruminococcaceae and Megasphaera. PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) analysis also showed that the abundances of pathways related to butyrate metabolism and tryptophan metabolism were increased; however, the function of lipopolysaccharide biosynthesis proteins was significantly decreased. The results demonstrated that 0.15% CT could improve growth performance, digestibility, and intestinal function of weaned piglets, and it had the potential to replace ZnO applied to farming.

D013634 Tannins Polyphenolic compounds with molecular weights of around 500-3000 daltons and containing enough hydroxyl groups (1-2 per 100 MW) for effective cross linking of other compounds (ASTRINGENTS). The two main types are HYDROLYZABLE TANNINS and CONDENSED TANNINS. Historically, the term has applied to many compounds and plant extracts able to render skin COLLAGEN impervious to degradation. The word tannin derives from the Celtic word for OAK TREE which was used for leather processing. Tannin
