项目摘要

Impoverished environments, such as small barren cages, can adversely affect animals' interactions with each other. Interactions needed for productivity (e.g. mating, maternal care) can be impaired; interactions that reflect or cause good welfare (e.g. play) often decline; and aggression often increases. This holds for many species, but in laboratory mice, for instance, enriched-housed mice are better than barren-housed mice at producing and raising viable pups, and (especially if female) they fight less with cagemates. I will therefore investigate how the behavioural, cognitive and 2) anxiety- and depression-like changes (anhedonia and negative judgment biases) reduce motivations for positive social interactions and cause predispositions to interpret neutral social cues as threatening. Mice (C57Bl/6, DBA/2 better at demonstrating information in social learning tasks; preferred over barren-raised females as cage-mates; and better stress buffers' than barren-raised females; b) enriched-raised males are more attractive to females, and also induce better maternal care in those that they mate, than barren-housed males; and c) enriched females are better mothers (e.g. faster & more responsive in pup retrieval tests), and that pregnant/lactating females prefer enriched females to barren-raised females as communal nesting partners. As potential mediators of all effects found, we will test the hypotheses that i) enriched mice are less perseverative (helping them make appropriate adjustments to changing social signals), and that ii) enriched mice find social contact more rewarding and less threatening than do barren-reared mice. How impoverished environments compromise social interactions has never before been systematically investigated, and the hypotheses under test are novel. This work has broad application, not just for laboratory mouse breeders & colony managers, but beyond to farm, zoo & other laboratory animals, via identifying environmental improvements as potential ways to boost both productivity and welfare by reducing social problems.
贫穷的环境,如小而贫瘠的笼子,可能会对动物之间的相互作用产生不利影响。生产力所需的互动(例如交配、产妇护理)可能会受到损害;反映或导致良好福利的互动(例如游戏)往往会减少;攻击性往往会增加。这适用于许多物种,但在实验室小鼠中,例如,在繁殖和饲养可存活的幼鼠方面,有丰富住所的老鼠比没有住所的老鼠更好,而且(特别是如果是雌性的)它们更少与笼子打架。因此,我将研究行为、认知和类似焦虑和抑郁的变化(快感缺乏和消极判断偏差)如何减少积极社交互动的动机,并导致倾向于将中性社交线索解读为威胁。 小鼠(C57BL/6,DBA/2)在社会学习任务中更善于展示信息;与缺乏饲养的雌性相比,它们更适合作为笼中伴侣;以及更好的压力缓冲能力;b)富裕饲养的雄性比没有饲养的雄性更吸引雌性,也能为它们交配的雌性提供更好的产妇护理;c)富裕的雌性是更好的母亲(例如,在取回幼崽的测试中速度更快,反应更灵敏),怀孕/哺乳期的雌性更喜欢拥有丰富的雌性,而不是不育的雌性作为共同的筑巢伙伴。作为已发现的所有影响的潜在调节因素,我们将测试以下假设:i)饲养丰富的小鼠不那么坚持不懈(帮助它们对不断变化的社会信号做出适当的调整),以及ii)饲养丰富的小鼠发现社会接触比不育的小鼠更有回报,威胁更小。 贫穷的环境是如何影响社会互动的,以前从未被系统地研究过,测试中的假设也是新颖的。这项工作不仅适用于实验室的老鼠饲养者和群体管理者,而且还适用于农场、动物园和其他实验室动物,因为它确定了环境改善是通过减少社会问题来提高生产力和福利的潜在途径。
