The objective of this study was to determine the effects of probiotics (Bacillus subtilis endorspores and Clostridium butyricum endorspores complex) supplementation on the apparent ileal digestibility (AID), apparent total tract digestibility (ATTD) and fecal noxious gas content in growing pigs. Three barrows [(Landrace � Yorkshire) � Duroc] with an average initial BW of 26.48 � 1.47 kg followed a 3 � 3 factorial arrangement of treatments (CON, P0.1, P0.2) with 3 levels of probiotics (0, 0.1, and 0.2%), respectively. In this study, the inclusion of probiotics increased (P<0.05) AID of dry matter (DM) and nitrogen (N) compared with CON group. Pigs fed P0.2 diet led to a higher (P<0.05) AID of energy than those fed CON diet. No difference was observed (P>0.05) on ATTD in the current study. Dietary probiotics decreased (P<0.05) the NH3, propionic acid and butyric acid concentrations compared with CON diet. In conclusion, dietary added probiotics supplementation increased AID and reduced fecal noxious gas content in growing pigs. 1311764827.php
