Sažetak

The social confrontation of a young growing pig with a comparable group immediately leads to very frequent agonistic interactions during the first 30 minutes accompanied with a rapid increase of heart rate and catecholamine concentrations and a delayed increase of cortisol concentrations. Confrontation of the animal with an unfamiliar group results in more agonistic interactions and a higher adrenocortical reaction compared to the confrontation with the familiar group. High rank animals have more agonistic interactions during the first 30 minutes, accompanied with higher heart rates and a higher adrenocortical reaction but show the ability to cope with the new situation after a short period. Further research is necessary to evaluate the existence of different adaptation strategies in pigs and the involvement in the observed physiological and behavioural reactions.
