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.

Abstract

This study aimed to evaluate the interaction between Palm Fatty Acid Distillate (PFAD) and high-tannin mangrove fruit extract (Sonneratia alba) on the in vitro digestibility of dairy cattle feed fiber fractions. The experimental design used a completely randomized factorial 3×4 pattern with three replicates. The first factor was the PFAD level (0%, 3%, 6%) and the second factor was the mangrove fruit extract dose (0%, 0.5%, 1%, 2%). Fermentation was carried out using the Tilley and Terry (1963) rumen stage method using fresh goat rumen fluid. The parameters observed included the digestibility of neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, and cellulose. The results showed that PFAD, mangrove fruit extract, and their interaction had a significant effect (P<0.05) on the digestibility of NDF and cellulose, but did not have a significant effect on ADF and hemicellulose. The combination of 3% PFAD and 0.5–1% extract provided the highest digestibility. Increasing PFAD and tannin reduced digestibility due to the fat coating effect and the formation of tannin complexes with structural carbohydrates. The combination of PFAD and mangrove tannin can be optimized as a functional feed additive based on local resources that improves rumen fermentation efficiency without reducing fiber digestibility.
