Abstract Although group housing of naturally social animals like rabbits (Oryctolagus cuniculus) is desirable for ethical reasons, social conflicts can significantly increase the risk for injuries as well as stress incidences and negatively affect their welfare. A common housing system in Switzerland is the "semi group-housing". Here, rabbit does are kept individually shortly before the birth of their kits until 12 days post-partum (pp) after which they are regrouped. Despite positive aspects of this housing system, like the reduction of pseudo pregnancy and crushing of kits, fights between the does often occur after the regrouping process. This study examined whether prolonged postpartum separation may reduce agonistic interactions, stress, and lesions. In total, data were collected over 5 trials on 57 Hycole breeding does. Per trial, three groups of 8 does each were artificially inseminated on day 10 pp and regrouped on either day 12, 18 or 22 pp. Non-pregnant does were replaced in every trial. Agonistic behaviour, anogenital distance, lesions and increased body temperature, as a stress indicator, were documented. The effect of the regrouping treatment on the rate of injury and agonistic interactions was different depending on the trial (lesions: interaction trial x treatment χ2 = 44.21, df = 8, P

半群养兔的不同重组时间表确实：对激动行为、压力和损伤的影响

摘要 尽管出于伦理原因，像兔子（Oryctolagus cuniculus）这样的自然群居动物的群体住房是可取的，但社会冲突会显着增加受伤和压力发生的风险，并对它们的福利产生负面影响。瑞士常见的住房制度是“半集体住房”。在这里，兔确实在它们的套件出生前不久被单独饲养，直到产后 12 天 (pp)，之后它们会重新组合。尽管这种住房系统有积极的方面，比如减少了假怀孕和破碎的工具包，但在重组过程之后，它们之间的争吵确实经常发生。这项研究检查了延长产后分离是否可以减少激动相互作用、压力和损伤。总共收集了 57 只 Hycole 育种的 5 次试验的数据。每次试验，三组每组 8 只在第 10 天进行人工授精，并在第 12、18 或 22 天重新组合。在每次试验中都更换了未怀孕的 do。记录了激动行为、肛门生殖器距离、病变和体温升高，作为压力指标。重组治疗对损伤率和激动相互作用的影响因试验而异（病变：相互作用试验 x 治疗 χ2 = 44.21，df = 8，P
