Data Sources and Methodology
The 4th edition of the Research.com Best Animal Science and Veterinary Universities in United States Ranking draws upon data primarily from OpenAlex and CrossRef, two of the most comprehensive bibliometric databases available. In addition, multiple other data sources were utilized to ensure the robustness and reliability of the insights gathered. All bibliometric data which informed the citation-based metrics for this ranking were systematically collected on 2024-11-27, ensuring up-to-date and relevant information.
Institutional rankings are determined by aggregating the D-indexes (Discipline H-index) of all scholars affiliated with each institution whose primary area of publication is Animal Science and Veterinary. The D-index is a discipline-specific metric that incorporates only those publications and citation data pertinent to the examined field. This allows for a precise measurement of research impact within the specified discipline.
Scope of Research
For the latest Research.com ranking, 279,971 scientist profiles identified from a diverse array of bibliometric sources were reviewed. From these, a subset of 43,427 scientists primarily focused on Animal Science and Veterinary was meticulously analyzed. To qualify, each scientist was required to have a minimum D-index of 20, with the majority of their scholarly output situated in Animal Science and Veterinary. Further, the ranking considered a scientist’s awards and other notable achievements within the field.
The D-index threshold for recognizing top researchers is incremented by 10, determined by the estimated total number of scholars within each discipline, ensuring that the most outstanding 1% of scholars are featured. A stringent proximity requirement stipulates that the difference between a scientist's overall H-index and their D-index does not exceed 30%, confirming their specialized impact in the discipline. Again, a scientist’s exceptional achievements and accolades within Animal Science and Veterinary are also considered in the evaluation.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot perfectly capture the caliber and contributions of researchers, the Research.com team conducted additional layers of validation. All profiles underwent manual verification and were corroborated with publications in a wide range of trustworthy sources. Although not directly influencing position within the ranking, the number of articles published in reputable journals and leading conference proceedings is acknowledged as a valuable secondary measure of a researcher’s impact in their field.
Notably, ranking positions are calculated using each researcher’s H-index as comprehensively reported by OpenAlex and CrossRef—both recognized as leading and reliable bibliometric databases by the research community.
