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

Melastoma (M) malabathricum L. is a phytochemically rich tropical plant with potential relevance to methane-mitigation research in ruminants. This study aimed to characterize the tannin and saponin contents of different organs of M. malabathricum L. as a preliminary basis for evaluating its prospective use as a phytogenic resource for livestock. Samples were collected from Padang Pariaman Regency, West Sumatra, Indonesia, and separated into roots, stems, leaves, flowers, and fruits for analysis. Tannin content was analyzed using the hide powder method based on the Folin-Ciocalteu reaction, while saponin content was determined using the TLC scanner method. The results showed clear variations in both metabolites among plant organs. Flowers had the highest tannin content, whereas the roots had the highest saponin content. These findings indicate an organ-specific distribution of bioactive compounds in M. melabathricum L. and suggest that this plant may serve as a promising botanical resource for further studies on methane mitigation. However, as the present study was limited to phytochemical characterization, further in vitro and in vivo studies are required to verify the effects of this extract on rumen fermentation and methane production.
