5. Conclusion
The CIAD and CISD of CP and AA in FFRB and DFRB were less than in broken rice, but because of the lower concentration
of CP and AA, the concentration of standardized ileal digestible CP and AA is less in broken rice than in the other ingredients
evaluated in this experiment. The greater concentration of acid hydrolyzed ether extract in FFRB and the reduced
concentration of neutral detergent fiber are likely the reason for the improved CIAD and CISD of CP and AA in FFRB compared
with DFRB. The reduced concentration of neutral detergent fiber in FFRB and DFRB used in this experiment compared with
qualities used in previous experiments likely contributed to greater CIAD and CISD of CP and AA. However, experiments to
determine the quality and type of fiber in FFRB and DFRB need to be conducted to confirm the effects of fiber on CIAD and
CISD of CP and AA in growing pigs.
