https://arvinfomedia.com/myjournals/index.php/RHTAFR <p><strong>Research Horizons: Trends in Agriculture and Food Research</strong> is a peer-reviewed journal dedicated to publishing high-quality original research, critical reviews, and selected high-impact reprints in the fields of agricultural and food sciences. The journal emphasizes studies that integrate agricultural production systems with food science, prioritizing interdisciplinary research at the interface of crop and livestock production, food processing, and human nutrition. It provides a platform for research that advances scientific understanding, technological innovation, and practical applications in agri-food systems.</p> <p>Published half-yearly, the journal is available in both print and electronic formats, ensuring wide accessibility to the research community.​</p> en-US Research Horizons: Trends in Agriculture & Food Research https://arvinfomedia.com/myjournals/index.php/RHTAFR/article/view/456 <p>This study aims to evaluate the blanching process of wasted <em>Undaria pinnatifida</em> as a ruminant feed source by assessing chemical compositions, in vitro nutrient digestibility, rumen fermentation characteristics, greenhouse gas emissions, and rumen microbes. The blanching process was conducted at different temperatures (15 vs. 80 vs. 90 ^◦C) and times (2 vs. 4 min) to assess the chemical and mineral contents. Supplementation levels of <em>U. pinnatifida</em> (0 vs. 0.5 vs. 1 vs. 2%) were observed with the blanching process (non-blanching (NBL) vs. blanching (LOS)). Increasing blanching temperature and time decreased (p &lt; 0.05) dry matter, crude ash, and the mineral contents, including sodium, phosphorus, and arsenic. Moreover, LOS treatment increased (p &lt; 0.01) in vitro dry matter and neutral detergent fiber digestibility, ruminal pH, and the acetate-to-propionate ratio, but reduced (p &lt; 0.01) CH₄ (mL/g NDFD). Additionally, 2% of LOS treatment reduced the abundance of protozoa, fungi, fibrolytic microbes, methanogenic archaea, <em>Methanobrevibacter ruminantium</em>, <em>Methanosarcina barkeri</em>, and <em>Methanosphaera stadtmanae</em> (p &lt; 0.01). Therefore, blanching at 80 ^◦C for 2 min improved the nutritional profile by reducing antinutritional minerals. Subsequent in vitro fermentation suggested that supplementing the diet with 0.5–1% of LOS improved digestibility and altered fermentation, potentially reducing methane yield (per NDFD).</p> Chang-Hyun Baeg Seung-Min Jeong Arrynda Rachma Dyasti Wardani Ji-Yoon Kim Bu-Gil Choi Young-Ho Joo Hye-Seong Kim Yong-Hyun Do Jung-Jun Park Sam-Churl Kim Copyright (c) 2026 Research Horizons: Trends in Agriculture & Food Research 2026-09-24 2026-09-24 1–14 1–14
