Introduction Adult chicken meat demand is likely to increase. However, in reality the cultivation of chicken obstacles that growth is slower than broiler that has a short production period. Attempts to overcome these problems it has done poultry diversification through the development and cultivation of local chicken crosses a descendant among local male chicken with the female race. The local chicken crosses have relatively short production period so that more promising in supporting the poultry in Indonesia because it can be marketed at the age of 50-60 days. Currently the community health awareness is increasing. People prefer foodstuffs of animal origin in particular poultry-fat and low cholesterol. Consumption of excess fat and cholesterol in humans, harmful to health as it can lead to atherosclerosis (clogged arteries). Recommended fat consumption as much as 15-30% of the total energy consumption and recommended cholesterol <300 mg daily (Almatsier, 2001). Cholesterol is found in the blood along with triglycerides, phospholipids and apoproteins to form lipoproteins. Lipoproteins in the blood are Nurul Fajrih Universitas Nahdatul Ulama Lampung nunu.nurul91@gmail.com +6285255995139 ISSN: 2548-3803 Vol. 1, No. 2, December 2016 URL: http://usnsj.com/index.php/CJAH/article/view/CJAH001 © 2016 CJAH All rights reserved 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.
