The concentration of cortisol, oestradiol-17 beta , prolactin and the amount of social behaviour shown during oestrus were measured in 3 groups of 3 sows (Swedish X Swedish Yorkshire) grouped after weaning and correlated with aggressive behaviour. No relations between the amount of aggression received and any of the hormone levels were found. In contrast, the frequency and characteristics of the oestrous behaviour were related to the amount of received aggression; the sows that received the highest amount of aggression showed significantly less social behaviour during oestrus compared with the other sows.This difference in oestrous behaviour between dominant and subordinant sows suggests that detection of oestrus may be more difficult in subordinate animals.
