Bio Web of Conferences, 2025
One type of seaweed found on the Coast of Ambon Island is Porphyra sp., a red algae species from the Rhodophyta phylum utilized by the local community as a “sea vegetable” due to its beneficial nutritional and bioactive compounds, consisting of 24.6-40.0% protein, 0.2-2.8% fat, and 35.0-49.8% crude fiber. In an effort to address the challenges of poultry health and performance in the modern era, functional feed supplements have emerged as a promising solution. Functional feed supplements are feed additives that not only provide basic nutrition but also provide specific health benefits or improve certain physiological functions in livestock. Porphyra sp. has various names, according to its country of origin, including purple laver (England, United States, and Canada), karengo (New Zealand), nori (Japan), kim (Korea), and zicai (China). This review aims to synthesize various scientific literatures on the nutritional composition and bioactive compounds of Porphyra sp. endemic to Maluku and analyze its potential as a functional feed supplement for poultry. Scientific evidence shows that Porphyra sp. is rich in protein, polysaccharides, minerals, vitamins, and antioxidants, which can improve feed efficiency, growth performance, and poultry product quality. Furthermore, its bioactive compounds can modulate the immune response and maintain digestive tract integrity. Porphyra sp. has the potential to become a functional supplement in environmentally friendly poultry feed. While promising, challenges related to production availability require attention, as it has not yet been widely cultivated. Further research on optimal dosage and long-term impacts on poultry is urgently needed.

Veterinary World, 2025
Background and Aim: Silage plays a pivotal role in ruminant nutrition, significantly influencing rumen fermentation, animal productivity, and environmental sustainability. Despite extensive research on silage and fermentation, a comprehensive synthesis of global trends and collaborations in this domain has not been systematically explored. This study aimed to conduct a bibliometric analysis of global research on silage feed and its effects on rumen fermentation in ruminants. It sought to identify publication trends, leading contributors, research themes, and international collaboration networks, thereby informing future directions in ruminant nutrition research. Materials and Methods: A total of 1,007 documents published between 1961 and 2024 were retrieved from the Scopus database using targeted keywords. Bibliometric and network analyses were performed using VOSviewer, Bibliometrix (R package), and Microsoft Excel. Inclusion criteria were limited to peer-reviewed English-language articles focused on silage feed and rumen fermentation in ruminants. Data cleaning and preprocessing involved harmonization of author names, keywords, and institutional affiliations. Results: Publication output has increased significantly since 2010, with China, the United States, and Canada emerging as the top contributors. Major research themes include silage quality, microbial fermentation, methane mitigation, and feed efficiency. Core journals identified include Journal of Dairy Science and Journal of Animal Science. Leading institutions such as China Agricultural University and the University of Florida demonstrated high productivity and citation impact. Keyword analysis highlighted emerging trends, including microbiome, methanogenesis, and sustainability. Collaboration network analysis revealed strong regional clusters, with North America and Europe forming central hubs, while Asia and South America showed growing but less integrated networks. Conclusion: Research on silage and rumen fermentation has evolved from foundational studies to interdisciplinary approaches integrating microbiology, environmental science, and precision agriculture. The field is rapidly expanding, with increasing emphasis on reducing methane emissions and enhancing livestock performance through improved silage practices. However, global collaboration remains fragmented, particularly in underrepresented regions. Future research should focus on metagenomics, smart technologies (e.g., Artificial Intelligence and Internet of Things), and policy-driven strategies to optimize feed systems and support sustainable livestock production. Keywords: bibliometric analysis, international collaboration, methane mitigation, microbiome, rumen fermentation, ruminants, silage feed, sustainability.

Veterinary World, 2024
Background and Aim: Coat color is a phenotypic trait that is affected by many functional genes. In addition, coat color is an important characteristic of breeds in livestock. This study aimed to determine functional genes for coat color patterns in Sumatran native cattle in Indonesia using a genome-wide association study method. Materials and Methods: A bovine single nucleotide polymorphism (SNP) 50K BeadChip was used for the investigation. A total of 46 Sumatran native cattle of three colors as follows: Brown (36 animals), white (9 animals), and black (1 animal), were used as experimental animals. Results: Results showed that the SNP markers ARS-BFGL-NGS-75486 (p = 2.46×10-7) and BTB-01992588 (p = 1.06×10-5) were selected as two genetic markers for coat color variation in animals under study, which were located at the cytoplasmic FMR1-interacting protein 2 (CYFIP2) gene at BTA7 and small G protein signaling modulator 1(SGSM1) genes at BTA17, respectively. The polymorphic informative content values of both SNP markers were 0.33 (ARS-BFGL-NGS-75486) and 0.13 (BTB-01992588). In this study, a genetic marker for coat color patterns in Sumatran native cattle was obtained based on the haplotypes of both SNP markers. Conclusion: It can be concluded that CYFIP2 and SGSM1 are two coloration genes that affect the phenotype characteristics of Sumatran native cattle. Keywords: cattle, coat color, functional gene, genome-wide association study, Sumatra.

Iop Conference Series Earth and Environmental Science, 2024
Assessment of the existence of macroalgae and revealing the chemical composition to investigate the potential usage for feed to support sustainable beef production has been conducted in Indonesian prominent livestock production area specifically Lombok, Bali, Yogyakarta, Lampung and Bengkulu. These regions host numerous seaweed production centres, while others hold the capacity to develop into seaweed cultivation zones. To assess the existence, utilisation, and accessibility of macroalgae in each region, observations and interviews were conducted. Subsequently, dominant macroalgae species were sampled and subjected to proximate analysis to determine their nutritional profiles. The results showed that the dominant macroalgae observed included red algae (Rhodophyta) like Eucheuma sp., Gracilaria sp., and Acanthophora sp., green algae (Chlorophyta) such as Ulva sp. and Caulerpa sp., and the brown alga (Phaeophyta) Sargassum sp. The dominant macroalgae found in all five observation sites with high abundance were Sargassum sp., Gracilaria sp., and Eucheuma cottonii. Ulva sp. and Eucheuma spinosum were present at four sites, while Acanthophora sp. and Caulerpa sp. were found at three sites. The dry matter content of the macroalgae ranged from 9.92% to 17.01%, with the highest values observed in the Eucheuma group (14.11%-17.01%). This was followed by Sargassum sp. (12.55 ± 2.40%), Ulva sp. (12.28 ± 2.33%), and Gracilaria sp. (11.09 ± 3.79%). Caulerpa sp. exhibited the lowest dry matter content (9.92 ± 1.29%). The crude protein (CP) content varied both within and between groups of algae species and observation sites. Gracilaria sp. exhibited the highest CP content (13.55 ± 0.16%), followed by Caulerpa sp. (11.87 ± 2.22%), Sargassum sp. (8.98 ± 0.42%), and Ulva sp. (6.98 ± 0.94%). The mineral content of the macroalgae was noticeably high, which is reflected in the low organic matter content. Ulva sp. had the highest organic matter content (80.17%), followed by Sargassum sp. (70.55%), Gracilaria sp. (66.53%), Caulerpa sp. (47.61%), and Eucheuma cottonii (43.50%). The readily available seaweed in this study tend to exhibit moderate to high protein and mineral content, making it a promising partial replacement or supplement for conventional feed, potentially contributing to sustainable beef production. Gracilaria sp., the most readily available seaweed, high in nutrient content with the potential to partially replace conventional feed protein sources. Its abundance of vitamins and minerals may enrich the overall value of the feed.

Calcium (Ca) is an essential mineral for eggshell formation and muscle contraction, and a lack of it can result in poor egg quality and decreased egg output in laying ducks. This study aims to see how feeding the mineral Ca in a ration containing Shrimp head meal and Bilis fish head affects the laying performance and quality of hatching eggs in Mojosari ducks. A total of 105 female and 15 male Mojosari ducks, aged 78 weeks, were raised for three months and randomly divided into 15 flocks (each flock containing seven females and one male duck). There were three kinds of treatment, namely P0 (control, without mineral), P1 (ratio of Shrimp head meal and Bilis fish head 2:1 + 1% mineral), and P2 ((ratio of Shrimp head meal and Bilis fish head 1:2 + 1% mineral). The findings revealed that adding mineral Ca to feed, including Shrimp head meal and Bilis fish head, had no significant influence (P>0.05) on laying Mojosari duck performance in terms of feed intake, egg production, egg weight, egg quality, ducklings produced, and income over feed cost (IOFC). Furthermore, Ca addition in the ration did not result in substantial increases (P>0.05) in fertility, hatchability, or egg size characteristics. Based on the findings of this study, feeding ducks with shrimp head meal and Bilis fish head can be used as an alternate calcium-free feed formulation.
