Evaluation of in Vitro Digestibility of Dried Matter and Organic Matter of Solid Waste of Bioethanol Fermentation from Cassava by Trichoderma Viride and Saccharomyces Cerevisiae

Abstract

This study aimed to evaluate the digestibility of dry matter and organic matter of Solid Waste of Bioethanol Fermentation by Trichodermaviride and Saccharomyces cerevisiae. The research was conducted in the Laboratory of Animal Nutrition Ruminant Livestock and Food Chemistry, Faculty of Animal Husbandry, Padjadjaran University, using the in vitro with sheep rumen fluid. The design of the study was a completely randomized design with 4 treatments and 5 replications. The treatment consisted of four rations as followed: R1 used 100% of grass; R2 = 50% grass + 50% concentrate; R3 = 50% of grass + 25% of concentrate + 25% of fermentation products; and R4 = 50% of grass + 50% of fermentation products. Parameters measured were dry matter digestibility and organic matter digestibility. The results of this study indicate that the addition of fermentation products into the ration had real effect (P <0.01) on dry and organic matter digestibility. The R3 ration treatment had the highest level digestibility of dry matter and organic matter, which was 77.06% and 49.59% respectively.
