Sixty crossbred (Duroc × Landrace × Large White) piglets were used to study the effects of Aspergillus oryzae fermented soybean meal (FSBM) and unfermented soybean meal (SBM) on growth performance, digestibility and activities of intestinal enzymes. All piglets were weaned at 35 days and randomly allotted to two treatments and fed diets containing SBM and FSBM, respectively. Faeces of piglets were collected during a period of 3 consecutive days between 48 and 50 days of age for digestibility measurements. At the end of the experiment, six piglets of each treatment were slaughtered humanely to collect the intestinal contents. The experimental results showed that piglets fed FSBM had an increase (P
