Tendência na Produção Científica no Contexto do Melhoramento Genético em Bovinos de Corte: Um Enfoque para Genes Relacionados à Qualidade de Carne.

Abstract

The objective of this study was to evaluate the scientific information in the beef cattle breeding in the last 48 years (1964-2012). The data gathering was compiled using the SCOPUS database, through the key words beef* , cattle* and breeding* . We retained all articles that include information about year and period of publication, author nationality and filiation, document type and scientific area. We found 1.946 studies published between 1946 and 2012. We noted an expressive increase on studies about genetic breeding of beef cattle since the end of 80´s till 2004. From the total, we found 1.717 original articles. We found that 21 of the 169 authors were responsible by 30% of publications. The majority of the published articles were from agricultural and biological science (55%) areas of knowledge. On the journal evaluation, Journal of Animal Science was the first with 696 articles and the Revista Brasileira de Zootecnia, a Brazilian journal, was the fourth. When we evaluated the institutional filiation the USDA (75) was first, UNESP (72), USP (54) and Embrapa (54) were second, sixth and seventh, respectively, more productive centers. Brazil is the second in number of articles. Considered all journal in which at least one article was published about beef cattle breeding, the observed mean impact factor was 1.75 (±1.75). Angus was the most cited bovine breed and the main research objective in animal breeding was Genetic with 596 articles, whereas the most studied genes were CAPN1 and CAST, used in 62% of all articles found, and the most used molecular markers was SNPs, found in 70% of the articles. Based on scientometrical analysis, we observed that the scientific production about cattle breeding is according to beef cattle market, wherein countries like United States and Brazil highlights. Other studies using meta-analysis, for example, should be done to confirm data obtained in this work.
