Global research landscape and transfer-oriented synthesis of diet-based enteric methane mitigation in ruminants (2005-2025): A bibliometric and implementation-focused review.
Article in Veterinary world, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aim: Enteric methane (CH Materials and Methods: A combined bibliometric and structured literature review approach was employed. A Scopus-indexed dataset (2005-2025) comprising 3,070 English-language documents from 456 sources was analyzed using the Bibliometrix package in R to evaluate publication trends, authorship patterns, country contributions, and collaboration networks. Concurrently, a structured narrative synthesis was conducted to classify dietary mitigation strategies into an implementation-relevant taxonomy and to identify constraints influencing cross-country transferability, including feeding systems, delivery mechanisms, and regulatory readiness. Results: The field exhibited rapid growth (18.38% annual growth rate), with nearly half of the publications produced since 2021. Research output involved 7,720 authors across 93 countries, reflecting strong collaboration (12.1 authors per paper; 37.72% international co-authorship) but significant concentration of influence among leading countries. The intervention landscape was organized into two principal categories: basal diet manipulation and feed additives/rumen modifiers. While numerous strategies demonstrated mitigation potential, their scalability depended largely on system compatibility, dose assurance, measurement, reporting, and verification (MRV) capacity, and regulatory frameworks rather than biological efficacy alone. Grazing-dominant and smallholder systems faced greater transfer constraints compared to confined feeding systems. Conclusion: Diet-based methane mitigation research has evolved into a rapidly expanding, collaborative field; however, practical implementation remains limited by system-specific and institutional factors. Effective mitigation at scale requires context-adapted intervention portfolios aligned with local feeding systems, infrastructure, and regulatory environments. Integrating bibliometric insights with a transferability-focused framework provides a robust basis for prioritizing research and guiding policy and industry adoption without compromising ruminant productivity.
