Evaluation of Chemical Composition and Lipid Components in Maize Straw based Complete Feed Diets Supplemented by Conden Tannin and Myristic Acid

Although maize straw as an agricultural by products could be used as an alternative feed ingredient for ruminants, its low nutritional value and palatability require an early processing. Supplementation of feed additive that functions as a methane inhibitor. The study was to examine the chemical composition in maize straw based complete feed diets supplemented by conden tannin and myristic acid. The experimental method used a group-randomized trials by ANOVA with 4 dietary treatments and 3 replications. The treatments are T1: Maize Straw Based Complete Rations (Control Diet), T2: Control diet +Mimosa powder (MP) 1,5%/kgDM + Myristic acid (MA)2%/kgDM, T3: Control diet + MP 1,5%/kg DM + MA 3%/kg DM, and T4: Control diet + MP 1,5%/kg DM + MA 4%/kg DM. Proximate and van soest analysis was analysed in the Feed and Nutrition Laboratory, animal Science faculty, Brawijaya University, Malang. The result showed that the maize straw complete feed without supplemented has not different with a chemical compositions Maize straw with 3 level of Conden tannin and myristic acid supplementation. Besides higher EE components contained on T4 which supplemented by CT 1,5 %/kg DM and MA 40 g/kg DM. It can be concluded that CT and MA in Maize Straw based complete feed diets can be used as rumen modifier without effected on chemical component.
