Abstract

Ruminant livestock production plays an important role in providing animal protein sources, but faces major challenges in terms of feed utilization efficiency and environmental impact due to methane emissions. Methane produced by rumen fermentation not only contributes nearly 30% of global greenhouse gas emissions but also causes energy losses of 7-12% of total feed energy. This study aimed to evaluate the effect of gambier (Uncaria gambier) leaf extract from Pangkalan, West Sumatra, on the digestibility of fiber fractions (NDF, ADF, cellulose, hemicellulose) and methane gas production in ruminant rations. The study was conducted in vitro using the method of Tilley and Terry (1963) with a randomized group design consisting of four treatments: T0 (control without gambier extract), T1 (0.5% gambier extract), T2 (1% gambier extract), and T3 (2% gambier extract), with four replications using goat rumen fluid. Results showed that the addition of gambier extract significantly increased NDF and ADF digestibility to 64.30% and 63.77% at T3, respectively, compared to the control of 61.67% and 61.56%. Cellulose digestibility increased from 64.57% at T0 to 67.20% at T3, while hemicellulose increased from 64.78% to 67.44%. In addition, methane gas production decreased significantly from 22.45 ml/g DOM in the control to 16.67 ml/g DOM in T3, equivalent to a decrease of 25.74%. The optimal dose to increase fiber digestibility and decrease methane production was 2% gambier leaf extract (T3 treatment). Thus, gambier leaf extract from Pangkalan can be used as an effective natural feed additive to improve feed efficiency while reducing the environmental impact of ruminant farming.

Abstract

This study aimed to determine the effect of tannins from gambir leaf extract (Uncaria gambir) and mangrove fruit extract (Sonneratia alba) on crude fiber digestibility (CFD), crude fat digestibility, nitrogen-free extract digestibility (NFED), cellulose and hemicellulose digestibility, and methane gas production in vitro. This study employed an experimental design using a 3 × 3 factorial randomized block designed with three replications, with the source of rumen fluid used for each incubation as the blocking factor. Factor A, the addition of gambir leaf extract (GLE) tannin, consisted of A1 (0%), A2 (0.75%), and A3 (1.5%). Factor B, the addition of mangrove fruit extract (MFE) tannins, consisted of B1 (0%), B2 (0.75%), and B3 (1.5%), resulting in nine treatment combinations. The variables observed in this study were CFD, crude fat digestibility, NFED, cellulose and hemicellulose digestibility, and methane gas. Analysis of variance showed that GLE and MFE significantly affected the measured variables (P<0.01). A significant A x B interaction was also observed for the measured parameter (P,0.01), indicating that the effect of GLE supplementation depended on the level MFE supplementation and vice versa. CFD values ranged from 60.04–67.61%, crude fat digestibility values ranged from 59.76–68.56%, NFED values ranged from 60.77–70.17%, and cellulose digestibility values ranged from 62.72–67.69%. Hemicellulose digestibility ranged from 66.50–70.75%, and methane gas production ranged from 14.67–28.00 ml. The combination of 0.75% GLE and 1.5% MFE yielded the best results in improving nutrient digestibility and reducing methane gas production.
