The object of this study was to investigate different levels of extruded rice product(Nutri-RS®) supplementation as an alternative to lactose on growth performance, diarrhea score, fecal E.coli and volatile fatty acid(VFA) in weaning pigs. Treatments were 1) Control(basal), L3(basal+3% extruded rice product), L6(basal+6% extruded rice product). The control diet in Phase I and Phase II contained 16 and 9% of lactose, respectively. For the feeding trial, a total of 81 crossbred pigs, averaging 7.56±1.18 kg body weight, were allotted to three treatments in three replicates with nine pigs per pen by RCBD. The experimental period was total 5 weeks. During the whole experimental period, there were no significant differences in growth performance, diarrhea score, fecal volatile fatty acid concentration among all treatments. Although there were no significant differences, pigs fed diet of L6 tended to show higher BW and ADG, ADFI, and fecal volatile fatty acid concentration compared to other treatments. Treatment L6 showed the lowest fecal E. coli count among all treatments(P<0.05). These results suggested that inclusion of extruded rice product has similar performance a with 6% of lactose in diet for weaning pigs and reduce approximately 9% production cost of weaning pig's diet. Therefore, extruded rice product could be utilized as an alternative feed ingredient to lactose in weaning pig’s diet.
