Abstract: The aim of the study was to investigate the effects of the supplementation of chestnut (Castanea sativa Mill.) tannin and/or organic acids in diets for pigs on their growth performance and the faecal microbial composition from 23 to 127 days of age. The dietary treatments consisted of a basal diet (control (C)), the basal diet added organic acids (OA), and the basal diet added organic acids plus tannin (OA+T). Animals were weighed on days 23, 82 and 127. Pigs fed the OA and OA+T diets showed during the grower period significantly higher daily gain (ADG)(P<0.05), improved feed conversion ratio(FCR) (P<0.05) and lower levels of E. coli (P<0.05) compared with C pigs. From 82-127 days only the pigs fed the OA+T diet significantly diminished (P<0.05) the total count of E. coli. (5.21 ± 0.24 vs. 4.86 ± 0.28 vs. 4.24 ± 0.28 log10cfu/g; respectively for C, OA and OA+T; P<0.05), elevated the total count of Lactic acid bacteria (6.85 ± 0.10 vs. 7.15 ± 0.49 vs. 7.95 ± 0.50 log10cfu/g; respectively for C, OA and OA+T; P<0.05)and significantly increased ADG (P<0.05) (687 ± 23 vs. 712 ± 11 vs. 766 ± 12 g/day; respectively for C, OA and OA+T; P<0.05). The results from the present study indicate that the supplementation of chestnut wood tannins and organic acids can improve the growth performance in period from 82-127 days mainly by reducing harmful E. coli counts and by increasing counts of beneficial Lactic acid bacteria.
