In-Vitro Rument Liquid Characteristics (pH, VFA, and NH3) From Sugar Cane Top Fermented with Different Levels of Phanerochaete chrysosporium

Abstract

One of the limiting factors of utilization sugar cane top as animal feed was it’s lower digestibility and feed consumption compared to grasses. Sugar cane top can be consumed by cows as much as less than 1% dry matter based on live weight. This due to high lignin content of sugar cane top and difficult to digested by ruminant animals. Therefore, sugar cane top should be fermented first before being given to livestock using Phanerochaete chrysosporium fungi at different levels. Therefore, fermentation using Phanerochaete Chrysosporium fungi is an effort to improve the quality of sugar cane top. The purpose of this study was to determine in-vitro rumen fluid characteristics (pH, VFA, and NH3) from fermented sugarcane tops with different levels of Phanerochaete chrysosporium. The method used in the experimental was randomized block design (RBD) with 4 treatments and 5 replications. The treatments were P0: Sugar cane top fermented with 0% Phanerochaete chrysosporium, P1: Sugar cane top fermented with 5% Phanerochaete chrysosporium, P2: Sugar cane top fermented with 10% Phanerochaete chrysosporium and P3: Sugar cane top fermented with 15% Phanerochaete chrysosporium. The parameter measured was in-vitro rumen fluid characteristics (pH, VFA, and NH3). The results of the experiment indicated that the parameters shown significantly different for each treatment of in-vitro rumen fluid characteristics (pH, VFA, and NH3). The best result in this study was at P1 treatment (fermented with level of 5% Phanerochaete chrysosporium) that is the pH: 6.43, the VFA: 116 Mm and NH3: 5.78 M).
