The data are from a dairy farm for the period of two years (from January 2015 to December 2016). The SCC and TBC variables were transformed to somatic cell score (SCS) and log10 (LogTBC). Factor analysis, discriminant analysis and cluster analysis were used. Through factor analysis, it was found two factors that together explained 69.5% of the total data variation. The first factor represented the inverse relationship between lactose versus fat and protein content, while the second factor represented the inverse relationship among monthly milk yield versus SCS and LogTBC. The discriminant analysis identified that lactose and protein contents and SCS were the variables that had the greatest participation in the separation of the groups formed by the cluster analysis. The groups differed mainly by the monthly production of milk, composition and SCS. Finally, there are important multivariate relations between the variables milk production, composition and quality. 2019 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303160553039 https://www.redalyc.org/journal/3031/303160553039/ https://www.redalyc.org/journal/3031/303160553039/html/ https://www.redalyc.org/journal/3031/303160553039/303160553039.epub https://www.redalyc.org/journal/3031/303160553039/movil 10.4025/actascianimsci.v41i1.42568 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
