This study aims to evaluation the effect of Indigofera zollingeriana flour utilization inpoultry pellet ration on the content of the fiber fraction ,namely : Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL), hemicelluloses and cellulose. The experimental design used Completely Randomized Design(CRD),which consists of 4 treatments and 5 replicates. The treatments were the level of Indigofera zollingeriana flour utilization that were T0 = 0% Indigofera zollingeriana (control),T1 = 5% Indigofera zollingeriana, T2 =10% Indigofera zollingeriana, T3 = 15% Indigofera zollingeriana. The results showed that the Indigofera zollingeriana utilization had no significant effect (P>0.05) on the content of NDF, hemicellulose, cellulose but had significantly effect (P<0.05) to the content of ADF and highly significant effect (P<0.01) on the content of ADL. It was concluded that the use of 15% Indigofera zollingerian alowered the content ADF and ADL, unable to reduce the content fNDF and unable to increase the content of hemicellulose and cellulose.The use of 15% Indigofera zollingeriana is t h e b e s t 30.39% NDF; 9.42% ADF; 2.25% ADL; 20.98% hemicellulose and 4.53% cellulose.
