Abstract

This experiment aimed to evaluate the decrease of the fiber fraction of some agricultural and plantation residues after being treated with Fiber Cracking Technology (FCT) and urea. The residues included rice straw, oil palm frond (OPF), oil palm empty fruit bunch (OPEFB), cocoa pod and coffee husk. They were added with 5% urea and incubated in FCT at temperature 135oC and pressure 2.3 atm for 2.5 h. The experimental treatments were arranged as a factorial design 5 × 2, in which the first factor was various agricultural and plantation residues (rice straw, OPF, OPEFB, cocoa pod and coffee husk) and the second factor was FCT application (untreated and treated with FCT + 5% urea), performed in 4 replicates. All treatments were subjected to Van Soest analysis and in vitro digestibility test. The decrease of fiber fraction was confirmed with Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) methods. Results showed that FCT + 5% urea treatment decreased NDF, ADF, cellulose and lignin contents of all samples (P<0.05), and increased IVDMD and IVOMD in comparison to untreated samples (P<0.05). However, the treatment did not alter in vitro methane gas production and VFA profiles of the samples. Analyses using SEM, XRD and FTIR revealed that FCT + 5% urea treatment demolished cell wall component, decreased crystallinity index and cleaved fiber bonds. It was concluded that combination between FCT and urea 5% effectively enhances the quality of some fibrous feed materials.

Abstract

The Samurai 1 variety is a genetically mutated strain with superior agronomic characteristics and enhanced nutrient content. This study aimed to evaluate the effect of harvest maturity stages and fibrolytic enzyme (Sunsonzyme) treatment on the nutrient value, fermentative quality, and nutrient digestibility of Sorghum bicolor cv. Samurai 1 silage. The silage quality was assessed using a completely randomized design with a 3 x 3 factorial arrangement. Sorghum was harvested at three different maturity stages, namely 85, 90, and 95 days, with fibrolytic enzyme added at 0%, 0.025%, and 0.05% of the dry matter. In vitro fermentability and digestibility were evaluated using a randomized block factorial design, which was also based on the same three harvest stages and enzyme levels. Observed variables included the nutrient composition of the sorghum, physical characteristics and nutrient content of the silage, as well as in vitro fermentability and digestibility. The results showed a significant interaction between harvest maturity and enzyme level on lactic acid production and total volatile fatty acid (VFA). Harvest age significantly affected (p<0.05) all variables, while the treatment of fibrolytic enzyme significantly increased ammonia (NH₃) and total VFA concentrations, as well as reduced the fiber fraction of the silage (p<0.05). The harvest age of 90 days showed the best quality in terms of nutrients, silage, and rumen fermentability. The addition of enzyme levels up to 0.05% improved the fermentative quality of silage, reduced fiber fractions, and enhanced rumen fermentability.
