Figure 1.

Multiple correspondence analysis solution for the management of replacement animals upon arrival to the farm, on 161 southern Ontario sow farms. Different categories of biosecurity practices are displayed in this two-dimensional solution that explains most of the variability in the data. Categories occur closely together if they are correlated in their respective dimensions. The categories of each variable are labelled in descending numerical order, with a value of 5 indicating the practice considered to have the highest risk. See Table‚ÄČ 1 for a description of which value label corresponds to which category.
