This study aimed to evaluate the beneficial effects of novel hydrolysates produced by limited enzymatic broken rice (HEBR) on the growth performance, intestinal morphology, and gut microbiota of weaned piglets. During the enzymatic hydrolysis, the primary component of HEBR was maltooligosaccharides (significantly increased to 85.15% at 105min). Compared to that of the Control group, the average daily gain and feed efficiency, and the villus height in the jejunum and ileum of weaned piglets, was significantly higher in the HEBR group. An increase in Bifidobacterium and Streptococcus was observed in the duodenum and ileum, while a decrease in Escherichia-Shigella was detected in the duodenum, jejunum, ileum and cecum of the weaned piglets with consumption of HEBR. Collectively, supplemental HEBR in the diet helps regulate the gut microbiota and improve the growth performance and intestinal morphology of weaned piglets. Hence, HEBR has the potential to be used as a functional food.
