Abstract
The feeding inulin of dahlia tubers as a prebiotic related to the quality of the resulting product is a product low cholesterol. The research was aimed to examine the role of inulin as a prebiotic derived from dahlia flower tuber in the form of powder and extract on blood cholesterol, low density lipoprotein (LDL) and high density lipoprotein (HDL) of crossbred local chicken. The research was assigned in a completely randomized design with 7 treatments and 4 replications (10 birds each), treatments applied were T0: basal ration, T1: ration + 0.4% powder of dahlia tuber, T2: ration + 0.8% powder of dahlia tuber, T3: ration + 1.2% powder of dahlia tuber, T4: ration + 0.39% extract of dahlia tuber, T5: ration + 0.78% extract of dahlia tuber, T6: ration + 1.17% extract of dahlia tuber. The birds were reared for conditioning from day 1 until 3 week, and dietary treatment was given thereafter until 11 week of age. Parameters observed were blood cholesterol, LDL and HDL. The data were statistically analyzed according to ANOVA and continued to Duncan test at the level of 5% probability. The results showed that feeding inulin in the form of powder or extract significantly (P<0,05) decreased LDL and HDL, but not on blood cholesterol. In conclusion, feeding inulin in the form of powder in 1.2% (T3) and extract in 1.17% (T6), able to reduce levels of LDL and HDL but not yet capable of lowering blood cholesterol of crossbred local chicken.

Summary
E CJAH/Vol.1/No.1/1-5/December 2016 chylomicrons, very low density lipoprotein (VLDL), low density lipoprotein (LDL), and high density lipoprotein (HDL) (Sacher et al, 2004). Blood cholesterol levels are high resulting in accumulation of cholesterol in the body. High fat in the diet will result in increased levels of low-density lipoprotein (LDL) in the blood that is rich lipoprotein cholesterol (Muhajir, 2002), so that the necessary efforts to make low-cholesterol animal products, namely the addition of inulin as a prebiotic. Administration of prebiotic inulin as closely linked with the quality of the product that is low-cholesterol products. Previous research by Yusrizal and Chen (2003) reported that administration of inulin from chicory root of 1% real lower blood cholesterol levels compared to the control treatment on the broiler. This study aims to assess the role of inulin as a prebiotic to cholesterol, LDL and HDL local chicken blood crosses. Rations given treatment for 9 weeks of maintenance from 3 weeks to 11 weeks of age
