Data Sources and Metrics
The 5th edition of the Research.com Best Animal Science and Veterinary Scientists in Nigeria Ranking was primarily developed using bibliometric data sourced from leading databases such as OpenAlex and CrossRef, supplemented by multiple other reputable data repositories. The citation-based metrics that underpin this ranking were collected on January 12, 2026, ensuring up-to-date and robust data inclusion. A scientist's position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric measure that focuses exclusively on a researcher’s publications and citation impact within the specific discipline of Animal Science and Veterinary. This discipline-specific index enables a more accurate reflection of scholarly influence within the relevant field rather than a general research footprint.
Scope of Research and Qualification Criteria
The ranking examined a total of 279,971 scientist profiles identified across various bibliometric sources spanning all academic disciplines. Specifically for Animal Science and Veterinary, 3 scientists were evaluated in detail. To qualify for inclusion in the ranking, scientists were required to meet rigorous criteria including a minimum D-index of 20, with a majority of their tier publications concentrated in the Animal Science and Veterinary domain. Furthermore, consideration was given to their awards and professional achievements within the field. The D-index threshold to select top researchers is dynamically set in increments of 10, reflective of the total number of scholars estimated within each discipline, while ensuring representation of the top 1% of leading experts. Additionally, eligibility requires that the gap between a scientist’s general H-index and their D-index does not exceed 30%, ensuring domain-specific relevance and consistency.
Additional Verification Practices
Our team acknowledges that raw bibliometric data alone cannot fully capture the depth and quality of scholarly output. Therefore, each scientist’s profile underwent thorough manual verification and was cross-checked against publications listed in a broad range of authoritative and trustworthy sources to confirm accuracy. While the number of publications in prominent journals and conference proceedings is not a directly weighted factor in determining a researcher’s ranking position, it remains a valuable secondary indicator of a scientist’s contribution and influence within their specific research domain. The final positions in the ranking were established based on each researcher’s D-index, leveraging data gathered from OpenAlex and CrossRef, which stand as two of the most comprehensive and widely recognized bibliometric platforms available to the global research community.
