个体行为的一致性（称为动物个性）和对环境变化做出反应的行为可塑性是塑造个体行为的重要因素。它们之间的相关性被称为人格依赖可塑性，表明人格可以影响个体对环境的反应。在农场动物中，这可能会影响对管理变化或压力源的反应，但尚未进行研究。在这里，我们使用超宽带位置传感器来测量个性和可塑性的运动90奶牛小牛长达56天开始在小对住房的外壳，随后转移到更大的社会住房。这是第一次小牛被证明是不同的个性和可塑性的运动时，改变住房。性格和可塑性之间存在显著的相关性，即旅行距离（0.57），这意味着在成对住房中旅行最远的个体在社会群体中增加了更多的运动，而停留时间（-0.65），因为那些留在同一地区的人随着住房的变化而减少得更多，这表明了个性依赖的可塑性。此外，小牛符合其圈养伙伴的行为成对，但这并没有继续在组。因此，个性，可塑性和社会效应影响农场动物如何应对变化，并可以为管理决策提供信息。
Individual consistency in behaviour, known as animal personality, and behavioural plasticity in response to environmental changes are important factors shaping individual behaviour. Correlations between them, called personality-dependent plasticity, indicate that personality can affect individual reactions to the environment. In farm animals this could impact the response to management changes or stressors but has not yet been investigated. Here we use ultra-wideband location sensors to measure personality and plasticity in the movement of 90 dairy calves for up to 56 days starting in small pair-housing enclosures, and subsequently moved to larger social housings. For the first time calves were shown to differ in personality and plasticity of movement when changing housing. There were significant correlations between personality and plasticity for distance travelled (0.57), meaning that individuals that travelled the furthest in the pair housing increased their movement more in the social groups, and for residence time (− 0.65) as those that stayed in the same area more decreased more with the change in housing, demonstrating personality-dependent plasticity. Additionally, calves conformed to their pen-mate’s behaviour in pairs, but this did not continue in the groups. Therefore, personality, plasticity and social effects impact how farm animals respond to changes and can inform management decisions.
