One disadvantage of crude palm oil (CPO) as a feedstuff is its property of rapidly being rancid, and thus could decrease quality and palatability of ration. To over come the problem, an antioxidant is needed to prevent lipid deterioration. The aim of this research was to prevent lipid deterioration in broiler ration containing CPO using garlic and cumin as antioxidants. The experimental run in a factorial arrangement according to completely randomized design with 2 factors and 3 replications for each treatment combination. The first factors were either A1= control ration, A2= control ration + 0.2% garlic, A3= control ration + 0.4% garlic, A4= control ration + 0.6% garlic, A5= control ration + 0.02% BHT or B1= control ration, B2= control ration + 0.2% cumin, B3= control ration + 0.4% cumin, B4= control ration + 0.6% cumin, B5= control ration + 0.02% BHT. Butyl hidroksitoluena (BHT) is a synthetic antioxidant. The second factors were duration of storage, i.e. P1= 0 week, P2= 2 weeks, P3= 4 weeks. Parameters observed were water content, fat content and free fatty acid content of the ration. The results of the experiment indicated that use of both antioxidant garlic and cumin decreased (P<0.05) free fatty acid content and fat content, but the former did not affect water content as the later did. The best ration was ration containing either 0.6% garlic or 0.4% cumin as an antioxidant which was indicated by a decrease in free fatty acid and lipid contents so that could slow down lipid deterioration in the ration. Use of garlic 0.6% or cumin 0.4% was better compared with the use of BHT 0.02%. Results also indicated that storage time affected (P<0.01) parameters in terms of increasing water content, free fatty acid content, and decreasing fat content

Quality of ration can be evaluated using several methods, such as chemical, biological and physical test. Physical characteristics of ration are important aspects in feed mill industry, because they are related to handling efficiency, processing and storage. The purpose of this study was to evaluate the influence of using tapioca, bentonite and onggok binders on the physical characteristics of crumble ration. The treatmentswere commercial ration (basal ration) + 2% tapioca, basal ration + 2% bentonite and basal ration + 2% onggok. The parameters observed were water content, water activity, particle size, specific density, bulk density,compact bulk density, angle of heap, softness and impact resistance of crumble and durability. The experimental data were analysed using analysis of variance according to completely randomised design consisted of four treatments and five replications for each treatment and the differences among treatments were further tested using Duncan Multiple Range Test. The result of this experiment showed that the addition oftapioca, bentonite and onggok as binders affected(P<0.01) physical chracteristics of crumble. It affected water content, water activity, bulk density, compactbulk density and durability. Particle size of ration with binders was significantly different from commercial ration. Ration with tapioca binder had the lowest value for water content and water activity, i.e. 9.42% and 0.84 respectively. Ration with bentonite binder had the highest value for bulk density, compacted bulk density, and durability, i.e. 0.686 g/cm3, 0.769 g/cm3, and 95%, respectively. Particlesize of ration which was binded with tapioca, bentoniteor onggok was categorised moderate compared to the commercial one.
