AB  - The aim of this study was to summarize the information related to the development of the scientific knowledge about the ram effect. Articles covering the topic were searched in several scientific databases and the origin of the authors, the year of publication, the journal in which the article was published, the number of authors and the sheep breed used was registered. Overall, 154 articles were obtained, most of which (43%) were published by Australian and New Zealand authors. The trend of the articles published outside Australia and New Zealand parallels the changes in the total number of sheep. Merino, Romney and Corriedale sheep were used in more than 50% of the articles. The general overview is that while in Australia and New Zealand the research has been developed during the eighties independently of the conjunctural needs, in the rest of the world depended more on market conditions.
