Relationships between presence of feed and water and aggressive behaviour and correlations between dominance and use of these resources were investigated in 64 five to eight week old pigs (Sus scrofa ). Pens of four randomly-selected pigs were established. Social dominance order was obtained largely within the first four hours but aggressive behaviour reached zero 19.4 hours after regrouping four pigs. Whether feed or water were present, pigs fought at similar levels. Pigs who were more aggressive did spend more time drinking water when resources were limited. Pigs that headed the aggressive dominance order did not gain preferred access to resources when they were in limited supply nor when they were abundant.
对64头5至8周龄的猪（野猪）进行了饲料和水的存在与攻击行为之间的关系以及优势地位与这些资源利用之间的相关性研究。建立了由四只随机挑选的猪组成的围栏。社会优势等级在前四个小时内基本确定，但在将四只猪重新分组19.4小时后攻击行为降至零。无论是否有饲料或水，猪的争斗程度相似。在资源有限时，攻击性较强的猪确实会花更多时间喝水。处于攻击优势等级首位的猪，在资源供应有限或充足时，都无法优先获取资源。
