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 investigated the effects of incorporating tannin-rich mangrove fruit (Sonneratia alba) into Indigofera zollingeriana-based rations on in vitro digestibility and rumen fermentation characteristics. Using a completely randomized design with four treatments (0%, 3%, 6%, and 9% S. alba) and four replicates, we evaluated dry matter digestibility (DMD), organic matter digestibility (OMD), crude protein digestibility (CPD), crude fiber digestibility (CFD), crude fat digestibility, nitrogen-free extract (NFE), rumen pH, volatile fatty acids (VFA), and ammonia (NH₃) concentrations. Results revealed that moderate tannin inclusion (6%) improved CPD and nutrient protection without significantly impairing DMD or OMD. However, higher inclusion (9%) significantly reduced CFD, crude fat digestibility, NFE, VFA, and NH₃ concentrations (P<0.05 or P<0.01), indicating suppressed microbial activity. These findings suggest that while S. alba tannins can effectively reduce ruminal protein degradation and modulate fermentation, excessive inclusion negatively impacts overall feed digestibility. The optimal inclusion rate was identified at 6%, balancing protein protection and fermentation efficiency. This study supports the strategic use of plant-based tannins as a feed additive to enhance protein utilization and reduce nitrogen losses in ruminant diets.

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

Penelitian ini mengkaji tentang potensi jerami bengkuang (Pachyrhizus erosus) sebagai pakan serat alternatif pengganti rumput. Tujuan percobaan untuk mendapatkan taraf optimal penggunaan jerami bengkuang sebagai pengganti rumput dalam ransum ternak ruminansia berdasarkan parameter kecernaan ransum secara in vitro. Percobaan menggunakan rancangan acak kelompok dengan 4 macam perlakuan dan 4 kali pengambilan cairan rumen sebagai kelompok. Perlakuan yaitu P0=30% rumput lapangan + 30% jerami bengkuang + 40% konsentrat, P1= 20% rumput lapangan + 40% jerami bengkuang + 40% konsentrat , P2= 10% rumput lapangan + 50% jerami bengkuang + 40% konsentrat, P3= 60% jerami bengkuang + 40% konsentrat. Konsentrat terdiri dari ampas tahu, dedak padi dan mineral. Peubah yang diamati adalah kecernaan bahan kering, bahan organik, protein kasar dan fraksi serat (NDF, ADF, selulosa dan hemiselulosa). Analisis ragam menunjukkan bahwa perlakuan berpengaruh berbeda tidak nyata (P>0.05) terhadap kecernaan zat makanan. Hasil penelitian disimpulkan bahwa jerami bengkuang dapat digunakan sebagai pakan hijauan alternatif pengganti rumput lapangan sampai 60% dalam ransum atau 100% pengganti rumput lapangan dengan rataan kecernaan bahan kering 59,64%, bahan organik 61,72%, protein kasar 67,07%, NDF 55,72%, ADF 53.12%, selulosa 53,73%, dan hemiselulosa 58,19%.
