The bibliometric data utilized for devising the citation-based metrics employed in this ranking were collected on January 12, 2026. The scientists featured in the ranking are positioned based on their D-index (Discipline H-index), a metric specifically tailored to reflect a researcher’s performance within a particular discipline. Unlike a general H-index, the D-index accounts only for publications and citation metrics that pertain to the examined discipline—in this case, Animal Science and Veterinary—thereby providing a focused and meaningful evaluation of expertise within the field.
Scope and Selection Criteria
This ranking comprehensively considered the profiles of 279,971 scientists identified from a variety of bibliometric databases across all scientific disciplines. From this extensive pool, 35 scientists specializing in Animal Science and Veterinary were identified and evaluated for inclusion in the South African context.
To ensure the highest standards of relevance and impact, eligibility for the ranking requires a minimum D-index of 20. Moreover, a majority of the scientist's tier publications must pertain to the Animal Science and Veterinary disciplines. Beyond citation metrics, the consideration of scientist awards and notable achievements within this field was incorporated to reflect broader recognition and contributions to the discipline.
The D-index threshold is not fixed arbitrarily; instead, it is set in increments of 10 relative to the total number of scholars estimated per discipline. This dynamic threshold-setting ensures that the ranking consistently includes the top 1% of leading scholars in the respective fields. Additionally, a proximity criterion is maintained such that the difference between a scientist’s general H-index and their D-index remains within 30%, safeguarding against disproportionate divergence between overall and discipline-specific impact.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the researchers behind this ranking undertook rigorous manual verification of all scientist profiles. Each profile was cross-correlated against publications from a wide range of trustworthy and authoritative sources, thereby ensuring the accuracy and validity of the data used.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s position in the ranking, it remains a valuable secondary signal of their contributions within Animal Science and Veterinary research.
To reiterate, the ranking position itself is strictly derived from the researcher's D-index as calculated from information gathered via OpenAlex and CrossRef. These databases are recognized as the most comprehensive and reliable bibliometric resources currently available, strengthening the methodological foundation of this ranking.
