The subject analysis of RIA publications provides crucial insights into the agricultural priorities and research investments during this period. The topics strongly aligned with INTA's institutional goals, focusing on economically significant areas for Argentine agriculture 2 .
Bovines emerged as the most frequently treated subject at 21.47%, reflecting the importance of cattle production in Argentina's agricultural sector 2 . This was followed by feeding research (8.90%), pastures (7.85%), rodents (6.81%), and pigs (4.71%) 2 . Collectively, these top five subjects accounted for 49.74% of the journal's thematic distribution, indicating a clear prioritization of livestock and related agricultural systems.
The prominence of bovines and feeding research underscores the significance of the livestock sector, while the attention to rodents suggests substantial research on pest control—a critical concern for agricultural productivity. The focus on pastures highlights work on sustainable feeding systems and land management.
Conducting a comprehensive bibliometric analysis requires meticulous methodology and specific analytical tools. The researchers employed various bibliometric techniques to extract meaningful patterns from the raw publication data 2 .
The foundation of any bibliometric analysis is exhaustive data gathering. For the RIA study, this involved first identifying all 90 contributions published across 14 volumes between 1964-1979 2 . Each article was systematically coded for multiple characteristics: author names and affiliations, reference details, subject classification, and publication metrics.
The researchers applied multiple bibliometric indicators to understand different aspects of the journal's impact and characteristics. The Price Index (0.78356 or 26.77%) measured the proportion of recent references, indicating how quickly researchers incorporated new knowledge 2 . The mean life of references (8.39 years) helped understand how long publications remained relevant to researchers 2 . Utility factor (7%) and self-citation rates (9.66%) provided additional insights into citation behaviors and knowledge integration patterns 2 .
A crucial aspect of the methodology was determining the core journals that constituted the fundamental knowledge base for RIA authors. Seven titles emerged as central, with six published in English and RIA itself being the only Spanish-language journal in this core group 2 . This core accounted for 35.77% of all journal references, while 16 journals collectively represented 50.40% of citations 2 .
| Core Journal | Subject Focus | Language | Significance |
|---|---|---|---|
| Journal of Animal Science | Animal production | English | Primary knowledge source |
| RIA | Agricultural sciences | Spanish | Local knowledge exchange |
| Journal of Nutrition | Animal/human nutrition | English | Feeding research foundation |
| Journal of Dairy Science | Dairy production | English | Bovine research applications |
| Journal of Agricultural Science | General agriculture | English | Broad agricultural knowledge |
| Australian Journal of Agricultural Research | Agricultural systems | English | Southern hemisphere perspective |
| Journal of Biological Chemistry | Basic science | English | Foundational biological processes |
The analysis also identified the most productive authors, with Massoia, E. (8.75), Giraudo, C.G. (5.08), Marchi, A. (5.08), Cercos, A.P. (5), Cairnie, A.G. (3,5) and García, Pilar T. (3,08) emerging as leading contributors 2 . When cross-referencing citing and cited authors, several names appeared prominently in both categories, indicating influential researchers who both consumed and produced significant knowledge within the field.
The bibliometric analysis of RIA transcends simple number-counting to reveal profound insights about how scientific knowledge circulates and evolves within specific communities. The findings demonstrate several important patterns that characterize agricultural research in Latin America during this period.
The dominance of English-language sources (75.97% of references) highlights the inescapable reality of English as the lingua franca of scientific communication 2 . However, the significant presence of Spanish sources (18.64%) also illustrates the vital role of regional knowledge exchange and the importance of maintaining scientific communication in the vernacular 2 . This bilingual citation pattern represents a strategic balancing act between global knowledge access and local relevance.
The collaborative nature of agricultural research (coauthorship index of 2.76) underscores how agricultural science had evolved into a team-based enterprise rather than individual scholarship 2 . Meanwhile, the subject concentration on bovines, feeding, and pastures clearly reflects Argentina's specific agricultural priorities and economic imperatives during this period 2 .
Perhaps most importantly, the analysis helps us understand how scientific communities construct their knowledge networks. The identified core journals represent the intellectual toolkit that RIA authors relied upon, while the self-citation rate of 9.66% indicates a healthy balance between building upon one's own work and engaging with the broader scientific community 2 .
The bibliometric analysis of Revista de Investigaciones Agropecuarias does more than document the past—it provides a framework for understanding how scientific fields evolve. The patterns uncovered in this analysis reflect a dynamic scientific community strategically navigating between global knowledge sources and local agricultural priorities.
