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 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

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.

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.

Abstract

This research was conducted to determine the effect of rice husk in a corn straw silage-based ration on the performance of Garut sheep. In this study, a completely randomized design (CRD) was used to determine the effects of rice husk on performance, digestibility, and organs. In this study, different amounts of rice husk were added to a corn straw silage-based diet, and each treatment was repeated five times. Twenty-five five-month-old male Garut sheep weighing 17.13±1.65 kg were divided into 5 groups, with one sheep per repetition. Each group was given an experimental diet consisting of the following: RH0 = 60% corn straw silage + 40% rice bran + 0% rice husk, RH1 = 60% corn straw silage + 30% rice bran + 10% rice husk, RH2 = 60% corn straw silage + 20% rice bran + 20% rice husk, RH3 = 60% corn straw silage + 10% rice bran + 30% rice husk, and RH4 = 60% corn straw silage + 0% rice bran + 40% rice husk. These findings indicated that higher levels of rice husk in the diet reduced performance, body weight, and weight gain and increased the weight of the digestive tract. Overall, the addition of rice husk in this study decreased the performance

Abstract

Program pengabdian masyarakat dilaksanakan pada peternakan itik yang berlokasi di Nagari Sungai Kamuyang, Kabupaten Limapuluh Kota. Usaha peternakan itik pedaging ini masih dikelola secara tradisional yaitu berupa perpaduan antara sistem perkandangan dan umbaran. Kondisi perkandangan yang memprihatinkan dan belum memadai merupakan kendala utama yang dihadapi peternak itik. Peternak melakukan umbaran pada persawahan yang ada di lingkungan sekitar kandang. Ternak itik dilepas di pagi hari dan kembali ke kandang disore harinya. Kondisi atap kandang yang bocor, pencahayaan yang buruk dan lantai tanah yang lembab menjadi penyebab ternak itik mudah terserang penyakit yang dapat menurunkan produktivitas. Kegiatan pengabdian ini bertujuan untuk memperbaiki manajemen sistem pemeliharaan ternak itik melalui renovasi kandang. Metode kegiatan yang dilakukan dalam pengabdian ini adalah pemberdayaan masyarakat partisipatif meliputi penyuluhan, pendampingan atau pembinaan. Pelaksanaan kegiatan pengabdian masyarakat berjalan dengan baik dan mendapatkan respon positif dari peternak. Kegiatan pengabdian dalam rangka merenovasi kandang ternak itik ini mampu mengatasi masalah peternak dalam hal penanganan penyakit ternak dan meningkatkan produktivitas ternak.

Abstract

The current COVID-19 pandemic has shaken many things. This condition makes the goat breeders of the ZCD (Zakat Community Development) program in Tanah Datar Regency demotivated because many activities and businesses are hampered. This year will plan to build a feed factory due to the assistance of the central ZCD and the establishment of business institutions. Until now, the plan is running in place because all activities that cause crowds have stopped. Sales of products, in the form of goats, also experienced significant disruptions. Moving on from these conditions, we held service activities with training and mentoring methods. The objectives of this activity are 1. They are renewing the enthusiasm and motivation of farmers in running a business, 2, providing knowledge and knowledge on how and stages of establishing a mini-feed factory, 3—providing knowledge and knowledge about the establishment of livestock business institutions. From the results of the activities obtained: (1), The COVID-19 pandemic has indeed disrupted the implementation of the ZCD program in Tanah Datar Regency (including the motivation of farmers), especially activities related to human interaction, but is currently recovering (2) Plans for establishing a mini-feed factory for implementation in 2021. However, breeders and managers better understand the stages to be carried out (3) ZCD managers already understand the plan to establish a livestock business institution to capture a reasonably large goat market opportunity from the internal of National Zakat Agency. The results of this activity suggest: (1) ZCD program activities should be re-run by applying the existing health protocols, (2) Establishment of ZCD member business institutions must be carried out immediately and recommended in the form of cooperatives.

Abstract

Toni Farm is a dairy goat enterprise located in Payakumbuh City that generates substantial quantities of organic waste, including goat manure, feed residues, and liquid effluents from the housing system. However, this waste has not been managed effectively, resulting in environmental pollution risks, reduced barn hygiene and animal welfare, and missed opportunities to create additional economic value for farmers. This community service program aimed to enhance farmers' knowledge and technical capacity through extension and mentoring activities on appropriate technologies for converting livestock waste into organic fertilizers suitable for small-, medium-, and large-scale farming systems. The program was implemented through educational outreach, demonstrations of organic fertilizer production, and hands-on training involving farmers at Toni Farm. The results demonstrated a significant improvement in participants' knowledge and practical skills in producing both solid and liquid organic fertilizers with commercial potential. In addition, the program contributed to reducing environmental problems associated with livestock waste accumulation. The utilization of livestock waste as organic fertilizer is expected to generate additional farm income while promoting the environmental sustainability of dairy goat production. Furthermore, the organic fertilizer produced at Toni Farm has strong potential to be developed into a locally based, environmentally friendly agribusiness product that supports sustainable agricultural development.
