Gut environment and microflora, digestibility, and performance were studied in weaned piglets in Central Vietnam fed a dry control diet (CO), a naturally fermented liquid diet (FE), and a liquid diet with inclusion of rice distiller's residue (RDR). Digesta samples were collected at the start (day 0) and at the end of experiment (day 42). Diet FE had a lower pH than diet RDR, contained more organic acids, had the lowest counts of E. coli and total coliforms (P<0.05), and the highest counts of lactic acid bacteria (LAB) (P<0.05). Piglets fed diets FE and RDR had lower pH (P<0.05), and higher concentrations of organic acids in the stomach, ileum and mid-colon (P<0.05) than piglets fed diet CO. Counts of LAB in stomach and ileum were higher in animals fed diets FE and RDR than CO (P<0.05), while the number of E. coli and total coliforms along the gastrointestinal tract was reduced. The ileal digestibility of crude protein and organic matter was improved in piglets fed diet RDR (P<0.05) compared with piglets fed diet CO. Piglets fed diet RDR had a higher weight gain (P<0.05) and a better feed utilization (P<0.05) than piglets fed the other diets. The present findings support the contention that fermented diets and/or fermented feedstuffs can be used for dietary manipulation to improve gut health and animal performance. (C) 2009 Elsevier B.V.
