  1. VHAT Voluntary Human Approach Test, TUFC time [s] until the first contact (touching the observer) of a pig with the person in the pen, TUOS time [s] until the observer is completely surrounded by pigs within a radius of approx. 2 m, PPSO percentage of pigs relative to group size [%] surrounding the observer after 1 min, PPAC percentage of pigs relative to group size [%] completely avoiding contact with the observer during the entire test period
  2. a study population: 1668 pig groups (pens) from 214 herds
