Abstract

Recently, fermentation of low quality feed such as agro industry by products has been widely applied to produce enriched animal feed and improve animal productivity. The purpose of this study was to evaluate in vitro digestibility of fermented complete feed by using agro-residues from sago starch processing industries as main source diet.  Feed was formulated on the basis of 40% sago residue and mixed with other ingredients (rice brand, coconut meal, bread by product, soybean meal and soybean hulls) to fulfill the requirement of sheep with 16,10% of CP, 2,80 Mkal ME/kg and TDN 60,88% based on calculation. Mineral and Urea were added in the complete feed to reach mineral and CP requirements of sheep.  Complete feed formulation was fermented by using 3 commercial fermentation products (Saus Burger Pakan® (SBP), Probion® and EM4®) for 21 days. Total and types of microbes from commercial fermentation products which were utilized in this study were not determined. Parameters measured in this study were pH, NH3, IVDMD (in vitro dry matter digestibility), IVOMD (in vitro organic matter digestibility) and VFA total. The model used for the statistical analysis was completely randomized design (CRD) with 4 treatments (control and 3 different commercial fermentation products) and 4 replications.  The results of this study indicated that administration of different commercial fermentation products into fermented complete feed based on sago residues significantly influenced (P<0.05) on pH, NH3, VFA total, IVDMD and IVOMD. Generally, commercial fermentation products mainly SBP produced better feed quality by improving the values of pH, NH3, VFA total, IVDMD and IVOMD. However, types and total microorganisms were needed to be determined before experiment.

Abstract

Sugarcane bagasse is one of agro-industrial residues containing low nutrient content and difficult to be digested by animals.  However, it can be recycled to produce value-added product such as protein-enriched animal feed by application feed technology such as ammoniation and fermentation. The purposes of these experiments were to evaluate the quality and in vitro digestibility of sugarcane bagasse by using two steps feed technology process: ammoniation and continued by fermentation process. Two studies were conducted in these experiments.  The first study was to determine the quality of amoniated sugarcane bagasse after incubation at room temperature at different days (0, 7, 14, 21, 28 days) and the second study was to determine in vitro degestibility of  ammoniated sugarcane bagasse fermented by using the various levels of sago flour (0%, 5%, 10% and 15% from sample total) and kept at room temperature for 21 day in an-aerobic condition. Parameters measured in this study were DM, CP, CF, pH, OM, IVDMD (in vitro dry matter digestibility), IVOMD (in vitro organic matter digestibility). The model used for the statistical analysis was completely randomized design (CRD). The results of the first study indicated that length of incubation was not significantly affect (P>0.05) on crude fiber content but had significant effect (P<0.05) on crude protein content but only for control treatment. For the second study concluded that administration of the various levels of sago flour into ammoniated sugarcane bagasse fermented with T.harzianum significantly influenced (P<0.05) on OM, IVDMD and IVOMD but had not significantly effect on pH value. The results of the study indicated that application 10% of soluble carbohydrate from sago flour was recommended for fermentation process based on the results of in vitro and fermented feed quality studies.
