项目摘要

The welfare of farm animals has become an area of increasing concern. A research priority cited by animal-user groups is the development of more objective methods of assessment of animal welfare. My proposal addresses this priority by developing new methods for welfare assessment. One recent conceptual innovation has been to use changes in cognitive functioning to assess affective states. Borrowing on experimental approaches designed to assess depression in humans, recently modified for use in animals, my research will test the effects of changes in affective states (such as those associated with social separation) on how dairy calves respond to ambiguous stimuli. Arguably equally important, and more practical to assess, are changes in anticipatory behaviours that may also be used to assess subjective states, so I propose a parallel series of experiments testing the effects of social separation on anticipatory behaviour. The social separation model is particularly relevant for dairy calves, as these animals are typically housed in individual pens or hutches. A growing body of literature on rats suggests that rearing animals with this level of social isolation can result in cognitive deficits, characterized by problems in memory and learning tasks. I propose a series of tests assessing the effects of social and individual housing on measures of cognition in dairy calves; these will be the first ever tests of the effects social isolation on cognition in farm animals. Thus the proposed experiments will contribute to the basic literature on the effects of social experience on learning, and use measures from learning experiments to assess changes in welfare associated with social isolation. My research will use robotic calf feeders to train calves in learning tasks; these feeders are becoming common on dairy farms, increasing the potential for future application of my findings on commercial farms. The funding will be largely devoted towards the training of scientists, helping to meet a growing demand for academics and professionals with expertise in animal welfare.
农场动物的福利已成为越来越受关注的领域。动物使用者团体提到的一个研究重点是开发更客观的动物福利评估方法。我的建议通过开发新的福利评估方法来解决这一优先事项。最近的一个概念创新是利用认知功能的变化来评估情感状态。借用旨在评估人类抑郁症的实验方法,最近修改用于动物,我的研究将测试情感状态(如与社会分离相关的情感状态)的变化对乳牛如何应对模糊刺激的影响。可以说同样重要的,更实际的评估,是预期行为的变化,也可以用来评估主观状态,所以我提出了一个平行的一系列实验测试社会分离的预期行为的影响。社会隔离模式与产奶犊牛特别相关,因为这些动物通常被圈养在单独的围栏或笼子中。越来越多的关于老鼠的文献表明,饲养这种社会隔离程度的动物会导致认知缺陷,其特征是记忆和学习任务出现问题。我提出了一系列的测试,评估社会和个人住房的影响,在奶牛的认知措施,这些将是有史以来第一次测试的影响,社会隔离的认知在农场动物。因此,拟议的实验将有助于社会经验对学习的影响的基本文献,并使用学习实验的措施,以评估与社会隔离相关的福利变化。我的研究将使用机器人小牛喂食器来训练小牛学习任务;这些喂食器在奶牛场越来越普遍,增加了我的研究结果在商业农场未来应用的潜力。这笔资金将主要用于培训科学家,以满足对具有动物福利专业知识的学者和专业人士日益增长的需求。
