Abstract
The aim of this work was to establish homogenous groups of cattle farms in the mountains of León, Spain, using the variables selected in a sister paper (this issue). Principal components analysis (PCA) was used to characterise and compare the different farms studied. Two classifications were established, the first taking into account the first seven axes selected by PCA, and the second by taking into account only the first two. A comparison of these systems led to the latter being selected. The final classification system involves eight groups based mainly on the orientation of production, size, productivity per breeding cow, and productivity per work unit.
Highlights
This work forms part of a study with the overall aim of establishing a farm typology that allows the current status of the cattle sector in the mountains of León to be analysed.The establishment of such a typology can be divided into two stages: the f irst involves identifying the variables responsible for the differences between farms, while the second establishes homogeneous groups according to these variables
This paper describes the second of the two stages mentioned above: the establishment of homogeneous groups of farms, using cluster analysis, for characterising the cattle farms of the mountains of León
The cluster analysis performed in this work involved the use of classification variables obtained via Principal components analysis (PCA)
