AbstractIn farm animals stress often occurs in chronic form. This problem is very important because the hormonal changes connected with social hierarchy affect the metabolic status. The experiment was carried out on 28 Polish Landrace x Polish Large White crossbreds gilts. Gilts were housed in straw bedded 240 x 350 cm pens in groups of 7 animals each. The two repeats of four day behavioural observations were made using video camera and time lapse video recorder. The ranking of gilts to the proper social hierarchy level on the basis of behavioural observations was made. Ranking of gilts was made on the basis of lying arrangement (taking lying places) and by the number and results of agonistic behaviour.
