这项研究测试了气质特质的两个主要特征，即跨时间的一致性和跨情境的一致性。感兴趣的气质特征是奶牛饲养期间的攻击性。在这项研究中，我们关注的是是否可以通过测量个体奶牛在饲喂过程中表达的行为反应来推断攻击性特征。攻击性行为出现在许多情况下，但本文重点关注圈养奶牛在饲料资源竞争的情况下的攻击性行为。重要的是，我们要充分了解奶牛在不同竞争和社会情况下攻击性的一致性。为了实现这一目标，我们研究了以下问题：（1）随着时间的推移，奶牛表达攻击行为的方式是否一致？ (2) 以及在标准和简化（竞争）界面的情况下？本研究的目的是以一种可以在商业农场上实际且轻松记录的方式测量圈养奶牛在喂养过程中的行为反应。将 10 头初产奶牛和 30 头经产健康泌乳牛分在一组（胎次 = 3.5 +/- 2.15；平均值 +/- S.D.）。饲料到达后 60 分钟内，记录攻击者和接受者每次攻击性互动的行为。重复性估计和肯德尔一致性系数都用于评估攻击者和接受者行为随时间的一致性。随着时间的推移，“攻击性指数”的奶牛内部重复性最高（r=0.31），无反应行为的重复性最低（r=0.04）。个人对标准和简化界面的反应与接触和非接触行为显着相关。这些结果强调了奶牛在饲喂过程中攻击性行为方式的复杂性，并说明攻击性饲喂行为的一些措施在奶牛中是可重复的。 (C) 2009 Elsevier B.V. 保留所有权利。
This study tests the two main characteristics of a temperament trait, consistency across time and consistency across situations. The temperament trait of interest was aggressiveness during feeding in dairy cattle. In this study, we focused on whether it is possible to infer a trait of aggressiveness from the measurement of behavioural responses expressed by individual cows during feeding. Aggressive behaviour appears in many contexts but this paper focuses on aggressive behaviour in a competitive situation over a feed resource in housed dairy cattle. It is important that we fully understand within-cow consistency of aggressiveness in different competitive and social situations. To achieve this the following questions were investigated: (1) are cows consistent in how they express aggressive behaviour over time? (2) and across situations at a standard and reduced (competitive) feedface? The aim of this study was to measure the behavioural reactions of housed dairy cattle during feeding in a way that can be practically and easily recorded on commercial farms. Ten primiparous and 30 multiparous healthy lactating cows were housed in a group (parity = 3.5 +/- 2.15; mean +/- S.D.). The behaviour of the aggressor and recipient was recorded for each aggressive interaction for 60 min after feed arrival. Repeatability estimates and Kendall's coefficient of concordance were both used to assess consistency of aggressor and recipient behaviours across time. The within-cow repeatability was highest for 'aggressive index' (r=0.31) and lowest for non-response behaviours (r=0.04) across time. Individual's responses to the standard and reduced feedface were significantly correlated for contact and non-contact behaviours. These results highlight the complexity of aggressive style of cows during feeding and illustrate that some measures of aggressive feeding behaviour are repeatable within cows. (C) 2009 Elsevier B.V.
