Activity budgets and use of enclosed space by wild boars (Sus scrofa) in captivity

摘要: This research was conducted on a captive group of eight wild boars: Four wildborn adults (one male and three females) four piglets females), born in captivity two months before the beginning study. They were housed Rome Zoo 1,000 sq m enclosure furnished with trees, mud pools, water basin, small barns. Data behavioral states (sleeping, resting, rooting, eating, walking, standing, scratching, nursing) collected by instantaneous sampling at 10-minute intervals. The spatial location each subject also noted, as well closeness to conspecifics. Results showed that differed their activity budgets. Activity patterns significant correlation mean temperatures. Furthermore, there difference use exhibit areas between piglets. This study suggests social structure which core is constituted females yearlings. nonbreeding female has more marginal position than breeding ones. Finally, tends be even peripheral solitary. Our results are partly consistent data obtained studies free-ranging boars (Mauget, 1980; Dardaillon, 1984).
