Objective: To characterize the scientific production of the Pastos y Forrajes journal during the period 1978-2021 and its relation to the paradigm changes in the research + development + innovation (R + D + i) processes of the Pastures and Forages Research Station Indio Hatuey. Materials and Methods: The dominion was constituted by the Pastures and Forages Research Station Indio Hatuey. Some bibliometric indicators related to the scientific production of this journal were described and evaluated. The study is classified as descriptive, longitudinal and retrospective. A total of 1 508 papers was recovered, and a database was created with the bibliographic manager EndNote X7. The analyzed indicators were the following: total published papers per year, geographic distribution, coauthorship index, collaboration networks of authors, co-occurrence networks for keywords, and most studied species. For the analysis of the thematic area the terms of the Agricultural Thesaurus AGROVOC and that of UNESCO were used. Results: In the first stage a higher quantity of papers about the introduction, evaluation and selection of pasture and forage species and varieties aimed at livestock feeding, was published, which was in correspondence with the existing genocentric model in the period. The second stage was marked by the papers related to the use of trees for animal production, with agroecological and sustainable approach, which was enhanced with the creation of the Socioeconomics group, which had a systemic and holistic vision of research. In the last stage the topics published in the journal were broadened and diversified, not only focused on cattle, but also on other species that can utilize the forage resources and created systems, with the inclusion of socioeconomic and environmental topics. Conclusions: The use of the bibliometric tools revealed high scientific and practical pertinence, which allowed to visualize the paradigm changes associated to the mission and the R+D+i lines. The most studied species have been Leucaena leucocephala andMegathysus maximus; while the most outstanding researched topics are: milk production, silage, nutritional value, silvopastoral systems, evaluation of plants, application of fertilizers and seed production.
