Basic manifestations were monitoring: standing, laying, feeding and moving. Strong difference was shown in social activity of groups in winter period (when were cattle in stable) - 18 contacts per a day for bulls vs. 7 contacts per a day for oxen. There were not marked different in social activity between bulls and oxen in summer monitoring (when were cattle on pasture). Other life manifests were comparable in both groups.In dependence of lower frequency of oxen social activity (in time when cattle are in limited place in stable) are oxen more tolerant to breeding technology. There is less number of aggressive behaviour in oxen also.
