农场动物的个性特征令人感兴趣，因为它们可以帮助预测个体行为和生产力的变化。然而，目前的人格特征是通过行为测试来推断的，这在研究环境之外是不切实际的。为了符合人格特质的定义，个体之间的相关行为差异必须在时间上和背景上都是稳定的。在这项研究中，我们使用了电脑喂奶器在两种情况下收集的数据，即结对饲养和集体饲养，以检验个体之间在喂食率和进餐频率方面的差异是否符合个性特征的定义。结果表明，个体间在摄食率和进食频率上的差异是相关的，对于每种行为，个体之间的差异在不同的环境中都是正相关的，并且显著相关。此外，喂食率和进食频率与体重增加呈显著正相关。总而言之，这些结果表明存在一种个性特征，即高进食频率、快速饮酒、快速生长的小牛在一端，而低进食频率、缓慢饮酒和缓慢生长的小牛在另一端。我们的结果表明，商业农场上已有的数据可以用来建立个性特征。
Farm animal personality traits are of interest since they can help predict individual variation in behaviour and productivity. However, personality traits are currently inferred using behavioural tests which are impractical outside of research settings. To meet the definition of a personality trait, between-individual differences in related behaviours must be temporally as well as contextually stable. In this study, we used data collected by computerised milk feeders from 76 calves over two contexts, pair housing and group housing, to test if between-individual differences in feeding rate and meal frequency meet the definition for a personality trait. Results show that between-individual differences in feeding rate and meal frequency were related, and, for each behaviour, between-individual differences were positively and significantly correlated across contexts. In addition, feeding rate and meal frequency were positively and significantly associated with weight gain. Together, these results indicate the existence of a personality trait which positions high meal frequency, fast drinking, fast growing calves at one end and low meal frequency, slow drinking, and slow growing calves at the other. Our results suggest that data already available on commercial farms could be harnessed to establish a personality trait.
