MCA graph of the farm descriptors with different levels of removal. Multiple correspondence analysis (MCA) graph showing the relations between management practices and housing conditions (gradient-coloured) and removal levels (in black) mortality <5% (M_5), <median (M_med) and < 15% (M_15) and culling < 30% (C_30), <median (C_med) and < 50% (C_50) in 43 farms in Finland, 2014. The two perpendicular coordinate axes are referred to as Dim1 (x) and Dim2 (y). To interpret the graph, the dark orange coloured categories are considered to have the strongest contributions, whereas the light blue ones the least, and the points close together in the same quadrants along a similar direction from the centroid would be indicative of possible associations. The acronyms of the farm variable categories are specified in Table 1
