Crude Protein And Fiber Fraction Of Corn Stover Inoculated By Fungi Trichoderma Sp. And Phanerochaete Chrysosporium

摘要

Abstract: Corn stover is an agricultural byproduct that can be potentially used as an alternative for ruminant livestock feed. One of the limiting factors in using agricultural byproduct as feed material is the presence of further lignification resulting in cellulose/hemicelluose bound by the lignin. Fiber degrading fungi produce extracellular enzyme that capable of breaking the lignocellulose bond. The objective of this study was to investigate the crude protein and fiber fraction of corn stover inoculated by fungi Trichoderma sp. and P. chrysosporium. This study used a complete randomized design with 7 treatments and 3 replications. T0: corn stover (control), T1: corn stover + 5% Trichoderma sp. incubated for 1 week, T2: corn stover + 5% Trichoderma sp. incubated for 2 weeks, T3: corn stover + 5% Trichoderma sp. incubated for 3 weeks, T4: corn stover + 5% P. chrysosporium incubated for 1 week, T5: corn stover + 5% P. chrysosporium incubated for 2 weeks, T6: corn stover + 5% P. chrysosporium incubated for 3 weeks. Variance indicated that corn stover inoculated with Trichoderma sp. and P. chrysosporium had a significantly effect on NDF, ADF, cellulose, hemicellulose, and protein content (P 0.05). This study indicated that crude protein and fiber fraction of the corn stover treated with Trochoderma sp. or P. chrysosporium were better than untreated.
