| Production information of 29 milk producers in the southern region of Chile was studied with the objective of characterizing and classifying different dairy production systems, evaluating various associations between quantitative and qualitative studied variables and analyzing the effect of the production system and the quality of bovine milk according to the month of the year that it was processed. The classification of production groups was based on the implementation of the exploratory multivariate technique, main components analysis and conglomerates or cluster analysis. The applied statistical model was: y ijk = µ + Mi + SPj + MSPij + e ijk, where y ijk=dependent variables (fat, protein, count of somatic cells and colony forming units); µ=general... |
