Quality Improvement of Sugarcane Top as Animal Feed with Biodelignification by Phanerochaete Chrysosporium Fungi on In-vitro Digestibility of NDF, ADF, Cellulose and Hemicellulose

Abstract

The aims of this research were to improve the nutrients digestibility of sugarcane top fiber fractions (ADF, NDF, Cellulose and Hemicellulose) through biodelignification process using Phanerochaete chrysosporium fungi as forage feed. This study used a randomized block design (RBD) with 4 treatments and 5 rumen fluid sources as a group. The treatments consisted of: A=sugarcane top (without fermentation), B=sugarcane top fermented with 5% Phanerochaete chrysosporium, C=sugarcane top fermented with 10% Phanerochaete chrysosporium, D=sugarcane top fermented with 15% Phanerochaete chrysosporium with fermentation times is 21 days. The results of experiment showed that dose of 10% Phanerochete chrysosporium with a fermentation time of 21 days could improve the digestibility of sugarcane top fiber fractions, as indicated by the higher digestibility of NDF (54.21%), ADF (53.06%), Cellulose (49.10%), and Hemicellulose. (57.73%).
