Introduction
⌅Since the last century, there is an exponential growth in the information sources and, at the same time, in the ways in which they are accessed, making it a challenge to identify what is relevant for decision-making (Rivas et al. 2023Rivas, F., Rosete, A., Cobas, M.J. & Hernández, A. 2023. Un análisis bibliométrico de la producción científica cubana en la web de la ciencia. Revista Cubana de Transformación Digital, 4(1): 1-16, ISSN: 2708-3411. https://rctd.uic.cu/rctd/article/view/204. ). Authors such as Arriojas and Marín (2021)Arriojas, D.D.J. & Marín, T.D. 2021. Producción científica en ingeniería: análisis comparativo de países de Suramérica del 2008 al 2018. Revista Universidad y Sociedad, 13(3): 84-93, ISSN: 2218-3620. http://scielo.sld.cu/scielo.php?script=sci_arttext&pid=S2218-36202021000300084. state that the production of scientific knowledge is essential for the development of countries, and its continuous increase is an essential task for research institutes and universities around the world. It is important to highlight that the development and dissemination of science go hand in hand with the economic and social development of nations; therefore, knowledge must be made available to the international scientific community for consultation and use (Povedano et al. 2020Povedano, F.J., Weinreb, R.N., Raga, I., Romero, A. & López, F. 2020. Detection of neurological and ophthalmological pathologies with Optical Coherence Tomography using retinal thickness measurements: A bibliometric study. Applied Sciences, 10(16): 5477-5491, ISSN: 2076-3417. https://doi.org/10.3390/app10165477. ).
In the field of science, researchers are published through specialized electronic journals and indexed for access in bibliographic databases (Vitón et al. 2019Vitón, A.A., Díaz, R. & Martínez, Y. 2019. Indicadores bibliométricos aplicables a la producción científica individual. Revista Universidad Médica Pinareña, 15(2): 273-284, ISSN: 1990-7990. https://revgaleno.sld.cu/index.php/ump/article/view/352/0. ). Scientific journals have played a crucial role in research management and development processes, becoming the primary means of communicating scientific results (Armengol 2017Armengol, N. 2017. Estudio bibliomérico de la revista Pastos y Forrajes, y su relación con los cambios de paradigma de I+D+i en la EEPF Indio Hatuey. Tesis en opción al grado de Máster en Ciencias en Pastos y Forrajes. Matanzas, Cuba.).
In Cuba, within the Agricultural Sciences, the Cuban Journal of Agricultural Science (CJAS) stands out, which publishes original and high-quality articles on topics related to the agricultural field: zootechnics (physiology, nutrition and management of ruminants and non-ruminants, microbiology and biotechnology), grasses, forages and other plants used in livestock, animal genetics, mathematics, economics, rural development, environment, sustainable agricultural systems, knowledge management, technology transfer, technological innovation and extension processes. The journal also has a (peer review) system and is indexed in regional and international databases (https://www.cjascience.com/index.php/CJAS). This availability to the international community gives relevance, credibility, and visibility to the journal's scientific output and to the authors who publish in it.
The journal's periodic production creates information flows across the various disciplines and thematic areas that inform researchers about the progress in their fields of study. Therefore, they become an important and tangible result that makes possible to measure and quantify aspects of scientific interest (López et al. 2021López, F., Velázquez, L.C., García, E., López, I. & Povedano, F.J. 2021. Análisis bibliométrico y mapeo de redes de la literatura científica internacional de la Academia de Ciencias de Cuba en la Web of Science (1968-1994). Anales de la Academia de Ciencias de Cuba, 11(2): 100-117, ISSN: 2304-0106. http://scielo.sld.cu/scielo.php?script=sci_arttext&pid=S2304-01062021000200009. ). In this sense, Bibliometrics emerges as the discipline that allows characterizing the scientific production of the journal, through the use of mathematical and statistical methods (Povedano et al. 2020Povedano, F.J., Weinreb, R.N., Raga, I., Romero, A. & López, F. 2020. Detection of neurological and ophthalmological pathologies with Optical Coherence Tomography using retinal thickness measurements: A bibliometric study. Applied Sciences, 10(16): 5477-5491, ISSN: 2076-3417. https://doi.org/10.3390/app10165477. ).
Bibliometric analyses of scientific production are necessary to assess the current state of research, as well as the contributions of researchers and countries in the fields of knowledge, which will allow future lines of research to be directed towards specific areas (Hurtado et al. 2022Hurtado, G. Díaz, J., Pérez, F., Araña, Y., Barcos, V. & Herrera, R. 2022. Análisis bibliométrico de publicaciones sobre el Proceso de Atención de Enfermería del período 2015-2020. Revista Cubana de Enfermería, 38(1): 1-14, ISSN: 1561-2961. http://scielo.sld.cu/scielo.php?script=sci_arttext&pid=S0864-03192022000100004. ). It should be noted that bibliometric analysis provides objective results of interest to both scientific journal editors and authors, given that it has become a reliable source of information on individual or joint production. Currently, other tools that are introduced in this type of analysis are bibliometric maps, which are very useful for visualizing the results (Franco et al. 2016Franco, K., Díaz, F.J., Pineda, J.E. & Hidalgo, C.A. 2016. Bibliometric analysis of scientific production of Mexican Journal of Eating Disorders. 2010-2014. Revista Mexicana de Trastornos Alimentarios, 7: 9-16, ISSN: 2007-1523. http://dx.doi.org/10.1016/j.rmta.2016.03.001. ).
Taking into account the above, the study aimed to carry out a bibliometric study to describe the performance of the publications from the Cuban Journal of Agricultural Science in the period 1967-2024 and to know the most published topics in recent years.
Materials and Methods
⌅Scientific production: A descriptive and retrospective bibliometric study was conducted on the scientific production of the Cuban Journal of Agricultural Science. To do this, the number of articles published per year between 1967 and 2024 was compiled for a total of 2,899. In the analysis, Price's law of exponential growth or first law of Bibliometrics was applied, which reflects an essential fact of scientific production, which is its exponential growth (Price 1963Price, D.J.S. 1963. Little Science. Big Science. New York: Columbia University Press.). To determine whether the data fit the exponential model, equation (1) was used for processing; Statgraphics version 5.1 plus (Anon 1995Anon. 1995. Software Statgraphics versión 5.1 plus [Windows].) and the statistical package Infostat (Di Rienzo et al. 2012Di Rienzo, J.A., Casanoves, F., Balzarini, M.G.,González, L., Tablada, M. & Robledo, C.W. 2012. InfoStat. Versión 2012, [Windows], Universidad Nacional de Córdoba, Argentina: Grupo InfoStat. Available at: http://www.infostat.com. ) were used.
where:
y(t):
dependent variable (number of publications) as a function of time
α; β:
exponential model parameters
t:
independent variable (time measured in years)
ℇ:
random error with zero mean and constant variance
In addition, two independent analyses were conducted. The first compared the journal's production by four-year period to determine which period(s) produced the largest number of publications. In the second analysis, production was compared by each of the journal's main sections (Biomathematics, Animal Science, and Grasses Science). In both procedures, a Chi-square proportion comparison analysis was performed for P<0.05 and the Fisher-Yates test (1958)Fisher, R.A. & Yates, F. 1958. Statistical Tables for Biological. Agricultural and Medical Research. Edinburgo: Oliver and Boyd, Escocia. was applied.
Key words analysis and bibliometric mapping: To study the most recent research topics, publications from the last 10 years (429 scientific articles) were compiled by the main sections: Biomathematics, Animal Science and Grasses Science. A database was created in the bibliographic manager EndNote version X7 (Clarivate Analytics 2014Clarivate Analytics. 2014. EndNoteTM. reference manager versión X7. Formaly the IP & Science business of Thomson Reuters. Toronto, Canadá.) and the necessary metadata related to the key words were extracted from each article and the database was converted into a text file for subsequent bibliometric analysis.
The relation between the key words of the publications for each section of the journal was obtained from the co-occurrence matrices in a net file generated with the Bibexcel program version 1.6.4 (Persson et al. 2009Persson, O., Danell, R. & Wiborg-Schneider, J. 2009. How to use Bibexcel for various types of bibliometric analysis. In celebrating scholarly communication studies: A Festschrift for Olle Persson at his 60th Birthday. (eds) Åström, F., Danell, R., Larsen, B. & Schneider, J. p. 9-24. Leuven. Belgium: International Society for Scientometrics and Informetrics.).
For the final visualization of these co-occurrence networks, bibliometric cartography or the mapping methodology proposed by Franco et al. (2016)Franco, K., Díaz, F.J., Pineda, J.E. & Hidalgo, C.A. 2016. Bibliometric analysis of scientific production of Mexican Journal of Eating Disorders. 2010-2014. Revista Mexicana de Trastornos Alimentarios, 7: 9-16, ISSN: 2007-1523. http://dx.doi.org/10.1016/j.rmta.2016.03.001. was used. In the bibliometric maps, each term was identified by a circle and the diameter length (label size) is related to the frequency of appearance of each term and its weight. In addition, as the distance between two circles is smaller, the co-occurrence of the terms will be greater. The different colors formed the different clusters with the most discussed topics in the publications. Each central cluster was identified by the main research topic for each journal section (Dextre et al. 2023Dextre, S.A., Febres, R.J. & Mercado, M.R. 2023. Análisis bibliométrico de los 100 artículos más citados en Scopus sobre educación médica y COVID-19. Revista Cubana de Información en Ciencias de la Salud, 34(1): 1-28, ISSN: 2307-2113. https://acimed.sld.cu/index.php/acimed/article/view/2196. ). To view the maps the VOSviewer program version 1.6.5 was used (van Eck and Waltman 2010Van Eck, N.J. & Waltman, L. 2010. Software survey: VOSviewer, a computer program for bibliometric mapping. Scientometrics, 84: 523-538, ISSN: 0138-9130. https://doi.org/10.1007/s11192-009-0146-3. ).
Results and Discussion
⌅Scientific production:Figure 1 shows the curve of the scientific production of the journal. By applying Price's law of exponential growth, the model only fit up to 2016 and managed to explain 70.17 % (R2) of the variability. According to López et al. (2021)López, F., Velázquez, L.C., García, E., López, I. & Povedano, F.J. 2021. Análisis bibliométrico y mapeo de redes de la literatura científica internacional de la Academia de Ciencias de Cuba en la Web of Science (1968-1994). Anales de la Academia de Ciencias de Cuba, 11(2): 100-117, ISSN: 2304-0106. http://scielo.sld.cu/scielo.php?script=sci_arttext&pid=S2304-01062021000200009. , when the model fit is greater than 65 %, the statements of the law are fulfilled, which is why an exponential growth in the scientific production of the journal was evident over the years.
After 1970, scientific production systematically increased, not only in the journal itself but also in Cuba, influenced by several important aspects of science. A research on Cuban science performed by García (2011)García, E. 2011. Revolución y ciencia en Cuba: la Academia de Ciencias de Cuba 1962-1972. Anales de la Academia de Ciencias de Cuba, 1(2): 1-32, ISSN: 2304-0106. https://revistaccuba.sld.cu/index.php/revacc/article/view/23/23 describes that in the 1970s there was an increase in research in multiple spheres, due to the role of the National Commission of the Cuban Academy of Sciences (founded in February 1962), which is recognized as the first multidisciplinary institution established after the triumph of the Revolution to carry out scientific researchers and provide services with high scientific-technical content.
By the 1990s, a paradigm change took place in Cuba, with a substantial increase in the way science was transmitted. During this period, scientific centers were created with the aim of promoting the development of biotechnology, the medical-pharmaceutical industry, and advanced technologies, to study, evaluate, and develop solutions in the fields of health and nutrition. In June 1994, the Ministry of Science, Technology and Environment (CITMA) was created, with the mission of directing, executing and controlling all State and Government policy in the areas of science, technology and the environment. By 1996, the Cuban Academy of Sciences was established as an official institution of the Cuban State, national, independent, and consultative with respect to science, representing the national scientific community. Another aspect to highlight within this systemic evolution of Cuban science was the organization of the network of Higher Education Centers in Cuba and the reorganization of the Science, Technology and Innovation Entities (ECTI) supervised by CITMA (Rivas et al. 2023Rivas, F., Rosete, A., Cobas, M.J. & Hernández, A. 2023. Un análisis bibliométrico de la producción científica cubana en la web de la ciencia. Revista Cubana de Transformación Digital, 4(1): 1-16, ISSN: 2708-3411. https://rctd.uic.cu/rctd/article/view/204. ).
Also, as part of the update of the country's economic and social development model, the Cuban State approved several policies between 2015 and 2020 to improve science, technology, and innovation activities. These new provisions make possible the introduction of institutional and individual incentives, linked to the scientific production of researchers and the impact of their results, and the creation of new economic figures in Cuba, such as Science and Technology Parks (STPs), interface enterprises between universities, ECTIs and the productive and service sector, and high-tech enterprises (HTEs) (Rodríguez and Núñez 2021Rodríguez, A. & Núñez, J.R. 2021. El Sistema de Ciencia, Tecnología e Innovación y la actualización del modelo de desarrollo económico de Cuba. Revista Universidad y Sociedad, 13(4): 7-19, ISSN: 2218-3620. http://scielo.sld.cu/scielo.php?script=sci_arttext&pid=S2218-36202021000400007 ). Díaz-Canel and Núñez (2020)Díaz-Canel, M. & Núñez, J. 2020. Gestión gubernamental y ciencia cubana en el enfrentamiento a la COVID19. Anales de la Academia de Ciencias de Cuba, 10(2): 1-10, ISSN: 2304-0106. https://revistaccuba.sld.cu/index.php/revacc/article/view/881/886. and other authors confirm that the advancement of science and continuous advice for decision-making in the different spheres of the country have contributed over the years to greater recognition of the importance of science as a component of technological sovereignty and national security in Cuba.
A bibliometric analysis carried out by López et al. (2021)López, F., Velázquez, L.C., García, E., López, I. & Povedano, F.J. 2021. Análisis bibliométrico y mapeo de redes de la literatura científica internacional de la Academia de Ciencias de Cuba en la Web of Science (1968-1994). Anales de la Academia de Ciencias de Cuba, 11(2): 100-117, ISSN: 2304-0106. http://scielo.sld.cu/scielo.php?script=sci_arttext&pid=S2304-01062021000200009. on the international scientific literature of the Cuban Academy of Sciences on the science website, from the 1960s to the 1990s, showed the performance of the scientific production of several research centers. The Institute of Animal Science stood out as the most productive institution with over 400 papers during analyzed period, and CJAS was identified as the core journal with the highest participation rate (PaR=56.34). In addition it was shown that the most productive authors in the analyzed period were: PhD. Arabel Elías, who contributed 8.26 % of the total documents, followed by PhD. Rafael S. Herrera with 4.13 %, and PhD Manuel Valdivié with 3.44 %, all three belonging to the Instituto de Ciencia Animal.
However, figure 1 shows a marked decrease in the number of annual CJAS publications starting in 2018. Specifically, in 2019, when the development of scientific researchers was affected by the COVID-19 pandemic and Cuba focused scientific studies on the search for medical products to mitigate the disease. Other factors that may have influenced on this performance were the high costs of raw materials on the international market and the lack of economic and financial resources that affected the country, particularly in activities related to food production.
When analyzing the number of articles published by the journal every four years, significant differences were observed (P=0.001) (table 1) The period between 1991 and 2018 highlight as the one with the highest production, with more than 200 articles published by the CJAS in each four-year period, surpassing the rest. In the years 1990-1994 (special period), publications were not affected, and the journal performed excellently and was on the rise. From 1998, the journal began publishing four times a year, rather than three times as previously, which contributed to the increase in the number of annual publications during that period. From 2023 onward, the journal published one issue annually, thus differing from the other analyzed periods.

When analyzing the number of published articles, there were significant differences between the main sections (P=0.001) (table 2). The Animal Science section stands out, with a total of 1,833 articles, representing 63.23 % of those published by the journal. This performance is explained because this section contributes the largest number of publications, based on the main researchers carried out by the institution and other centers, and the researchers who contribute the most to this section. Other notable sections include Grass Science, with 733 articles (25.28 %), and Biomathematics, with 118 (4.07 %). On the other hand, 215 papers were retrieved (7.42 %), which are related to studies on genetics or with economic aspects, among other topics.

Key word analysis and bibliometric mapping: In the Biomathematics section, the analysis of the frequencies of the terms and their relations managed to identify 173 terms defined by the authors as key words (figure 2). The most frequent key words in the articles of the last 10 years were seven: milk production (5), principal components (4), impact index (4), mathematical modeling (3), multivariate analysis (3), information criteria (3) and Statistical Model of Impact Measurement (SMIM) (3). The main cluster was related to milk production, variable modeling, impact measurement, as well as some of the multivariate analysis tools.
Table 3 shows the five clusters that relate to the 19 most frequently used pairs of co-occurrence of terms in the titles and abstracts of the publications.
| Cluster | Co-occurring terms |
|---|---|
| 1 | Rabbits, random effect, fermentation, mathematical modeling, programs |
| 2 | Impact indices, milk production, technologies |
| 3 | Multivariate analysis, main components, efficiency |

As a general result of the analysis, the key words with frequencies of appearance above five were: pigs (30), fermentation (24), rumen (12), cattle (10), rabbits (10), probiotics (9), feeding (9), laying hens (8), intake (8), quality (8), buffaloes (7), digestibility (7), grazing (7), morera (7), chemical composition (6), gas production (6), sheep (6), prebiotics (6), yeast (6) and nutrition (6). The results showed that recent studies focused on animal feeding, primarily in the pig, cattle, rabbit and laying hens categories, as well as on the use of different prebiotics and probiotics. Other notable researchers included studies on in vitro gas production, chemical composition, and the overall quality of these foods. The main cluster was related to researchers on pigs, and in almost all clusters, the word "food" highlighted as one of the most studied.
In the Grasses Science section, a total of 645 terms were identified as key words through analysis of term frequencies and their relations (figure 4). Eleven clusters were formed related to the 253 co-occurrence pairs of the most frequently used terms in the titles and abstracts of the publications (table 5).
In this section, a total of 17 key words were identified with frequencies of appearance above five, among which are digestibility (15), Tithonia diversifolia (14), Pennisetum purpureum (11), grasses (11), Cenchrus purpureus (10), yield (10), forage (10), chemical composition (9), Moringa oleífera (8), Bradyrhizobium sp.

Conclusions
⌅Bibliometric analyses proved to be useful in assessing CJAS's scientific activity. Their practical application allowed identifying the period of the journal's greatest scientific output, during which the Animal Science section highlighted. The journal's scientific output grew exponentially until 2016, with a marked reduction in the number of annual publications starting in 2018. Using key words the most frequently discussed topics in recent years could be identified. These analyses will help guide researchers in their future studies and the editorial team in designing guidelines and strategies for publishing scientific results and improving the journal's current positioning.
