  1. The traits were specified in column 1 using the following abbreviations: BFT backfat thickness, BCS body condition score, HH hip2hip, DL depthleft, DR depthright, VL volumeleft, VR volumeright, DPL distpinleft, APL areapinleft, DML distmidleft, AML areamidleft, DPR distpinright, APR areapinright, DMR distmidright, AMR areamidright (compare List of Abbreviations and camera trait description in paragraph "Further processing: application "ExT"" and Figure9). "NS" indicates that group means did not differ significantly. Means between cows were significantly different with very large effect sizes for all traits. Season effects were small to medium, except for "VL" within the Grub dataset.
