The bibliometric data utilized for devising the citation-based metrics in this ranking were collected on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively incorporates papers and citations pertinent to the specific discipline under examination, thereby ensuring focused and relevant evaluative outcomes.
Scope of Research and Ranking Criteria
The ranking process involved the examination of 279,971 scientist profiles identified from a diverse array of bibliometric sources spanning all academic disciplines. Within this extensive dataset, 16 scientists specializing in Animal Science and Veterinary disciplines were specifically evaluated.
To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 20, with a majority of their tier publications clearly situated within the field of Animal Science and Veterinary. Additionally, documented awards and achievements in this discipline were also considered in the vetting process.
The D-index threshold applied for selecting top researchers is established as increments of 10, corresponding to the estimated total number of scholars per discipline. This methodology guarantees inclusion of the top 1% of leading scholars within the list. Furthermore, a strict criterion maintains that the proximity between a scientist's general H-index and their D-index does not exceed 30%, ensuring the scholar’s specialized impact closely aligns with their overall research output.
Verification Practices and Methodological Rigor
We recognize the inherent limitations of relying solely on raw bibliometric data as definitive measures of scholarly output. Accordingly, all scientist profiles featured in the ranking underwent meticulous manual verification. This process included cross-correlating publication records against a wide range of trusted and reputable sources to ensure accuracy and relevance.
While the volume of papers published in prominent journals and conference proceedings is not a direct factor influencing a researcher’s ranking position, it is regarded as a valuable secondary indicator of a scientist’s active contribution to the field.
The ranking positions are established using each researcher’s D-index, as calculated from data aggregated through OpenAlex and CrossRef—the foremost bibliometric databases accessible to the research community today.
