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 explored the potential of gambir leaf extract (Uncaria gambir Roxb.) from Sutera, South Pesisir Regency, West Sumatra, as a natural feed additive to improve fiber digestibility and suppress methane emissions in rumen fermentation. The study was conducted in vitro using fiber-based rations added with gambir extract at 0%, 0.5%, 1%, and 2%. Parameters observed included digestibility of NDF, ADF, cellulose, hemicellulose, and methane gas production. Results showed that adding gambir extract up to 2% significantly increased fiber digestibility and decreased methane production compared to the control. This study proves that local gambir extract has the potential as an environmentally friendly feed additive to support the efficiency and sustainability of ruminant farming.

Abstract

This study aims to evaluate the effect of supplementing ruminant feed with gambir leaf extract (Uncaria gambir Roxb.) from Pangkalan, West Sumatra, as a natural feed additive on the in vitro digestibility of crude fat, crude fiber, and nitrogen-free extract (NFE). The study used a completely randomized design with four treatments: T0 (control, without extract), T1 (0.5% gambir extract), T2 (1% gambir extract), and T3 (2% gambir extract). The parameters observed included crude fat, crude fiber, and NFE digestibility. The results showed that gambir leaf extract supplementation had a significant effect (P<0.05) on all parameters tested. Treatment T3 provided the highest digestibility values, namely crude fat 66.47%, crude fiber 66.45%, and NFE 67.99%, compared to the control (64.17%, 64.52%, and 65.70%). This increase is thought to be due to the bioactive content of gambir extract, namely tannins (64.84%), catechins (60.11%), and saponins (0.96%), which work synergistically to modulate rumen microbes, protect nutrients from excessive degradation, and increase fermentation efficiency. In conclusion, gambir leaf extract from Pangkalan has the potential to be a natural feed additive that improves nutrient digestibility in ruminants. These results support utilizing local phytochemical-based resources for feed efficiency and sustainable livestock farming.
