The obsective of this study is to compare domestic chicory root powder with foreign chicory fructooligosaccharide (FOS) in effect of microflora in piglet feces and to sustitude domestic chicory for foreign chicory. The prebiotic effects of FOS from chicory (Chicorium intybus) was evaluated for livestock feed supplement. Chicory is a turberous plants containing inulin ,with high fructose contents its root. Piglets were fed one of three diets for 5 weeks, a control diet, a basal diet containing 0.2% of foreign chicory FOS and a basal diet containing 0.3% of domestic chicory root powder. Prebiotic effects of foreign chicory FOS and domestic chicory root powder were examined for their effects on the growth of fecal microorganism with piglet along with measuring pH changes of collected piglet feces during experimental periods (5 weeks). The results showed that the growth of Lactic acid bacteria (LAB) was significantly increased after feeding chicory FOS and chicory root powder supplemented feeds, and the increased occupancy ratio of LAB in the feces was observed. However, the occupancy ratio of Escherichia coli in piglet feces was continuously declined after treating feeds containing chicory FOS and root powder. No remarkable changes were observed in the growth of Clostridium perfringens throughout the experimental periods. A significantly decreased pH of the collected feces was observed after feeding chicory FOS and chicory root powder supplemented feeds. It was noteworthy that feeding chicory root powder more effectively decreased pH levels than those of chicory FOS. As a result of this it was expected that FOS from chicory could be applicable to pigs as prebiotics.
