Abstract

This experiment aimed to determine nutrient content, protein fraction, and in vitro rumen fermentation of some alternative beans in comparison to soybean. Samples used were napier grass, soybean, redbean, groundnut, pigeonpea, cowpea, bambarabean, and mungbean. Samples were determined for their proximate composition, Van Soest’s fiber fraction, and Cornell protein fraction. The samples were subsequently evaluated for their fermentation characteristics and digestibility by using a two-stage in vitro rumen fermentation technique, maintained at 39 oC for 2 × 48 h. The in vitro incubation was performed in three consecutive runs by following a randomized complete block design in which each sample per run was represented by four fermentation tubes. Results revealed that all experimental beans contained high crude protein (CP), i.e. above 200 g/kg dry matter (DM), but only soybean and groundnut had CP contents higher than 300 g/kg DM. Redbean had the lowest crude fiber and acid detergent fiber contents among the beans. Soybean contained high proportion of rapidly degraded CP fraction, but low in slowly degraded and unavailable CP fractions. High proportion of slowly degraded CP fraction was found in redbean and bambarabean. Redbean, pigeonpea, cowpea, and mungbean were better than soybean, groundnut, and bambarabean with regard to DM degradability and DM digestibility values (P<0.05). Concentration of total VFA was the highest in the incubation of redbean. It was concluded that groundnut, redbean, pigeonpea, cowpea, and mungbean have the potency to be used to substitute soybean for ruminant feeding.

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.
