Abstract

Rest is the etho-physiological activity with the most prolonged duration within the 24 hours: thus, males rest for about 61-62% of their time while females rest for about 66-68% of their time. Feed consumption in ad libitum feeding conditions lasts differently: thus, castrated males feed for about 16' 23" ± 0.44" while females feed for about 18'46" ± 0.62". Conflicts within the groups take place in 2.30 ± 0.34 sessions for attacks and in 0.45-0.83 session for defence fights. Attack sessions, foraging sessions, defecation sessions, and urinating sessions to differ between castrated males and females exploited in farming systems since neither feeding, nor living conditions are always acceptable and regular.
