Simulation maternal care improve welfare

项目摘要

For a domestic chick, the mother hen is an important role model; chicks learn a great deal from their mother about what to peck, when to rest and how to behave when there is a threat. However, in large farms, allowing hens to rear their own chicks is not commercially viable and in the UK last year, around 900 million domestic chicks were hatched in large incubators and reared artificially, without a mother hen. Chicks reared without a mother in this way are more fearful and more likely to develop behavioural problems, such as pecking the feathers and skin of other chickens; a highly prevalent and serious welfare concern. Since natural brooding is not an option on commercial farms, the aim of this project is to artificially simulate a number of important features of maternal care that result in healthy, less fearful, higher welfare chickens. For example, one method of simulating the mother's role in directing chick pecking activity might be to play recordings of maternal feeding calls near to feeders, to encourage the chicks to peck at food rather than the feathers of their brood mates. To develop these artificial simulations of maternal care, I will first observe how effective mother hens behave by identifying features of maternal care that result in less fearful, higher welfare chicks. After pinpointing the most effective features, small scale studies with non-brooded chicks will allow me to assess whether artificial simulation of these features is feasible and effective in improving chick welfare. Finally, candidate artificial features of maternal care will then be rolled out onto commercial laying hen farms to determine whether the welfare benefits can be replicated on a large scale and persist until the end of the production period. This project will not only provide fundamental new insight into avian maternal behaviour, but will result in practical and effective animal welfare solutions; a strategic priority for BBSRC.

对于一只家养的小鸡来说，母鸡是一个重要的榜样;小鸡从它们的母亲那里学到了很多关于啄什么，什么时候休息，以及当有威胁时如何表现。然而，在大型农场中，允许母鸡饲养自己的小鸡在商业上是不可行的，去年在英国，大约有9亿只家禽在大型孵化器中孵化，并在没有母鸡的情况下人工饲养。以这种方式饲养的小鸡在没有母亲的情况下更害怕，更有可能出现行为问题，例如啄其他鸡的羽毛和皮肤;这是一种非常普遍和严重的福利问题。由于自然育雏不是商业农场的一种选择，本项目的目的是人工模拟产妇护理的一些重要特征，从而产生健康，更少恐惧，更高福利的鸡。例如，一种模拟母亲在指挥小鸡啄食活动中的角色的方法可能是在喂食器附近播放母亲喂食的录音，以鼓励小鸡啄食食物而不是它们的育雏伴侣的羽毛。为了开发这些人工模拟母性护理，我将首先观察母鸡的行为如何有效，通过识别母性护理的特征，从而减少恐惧，提高福利。在确定了最有效的功能后，对非育雏鸡的小规模研究将使我能够评估人工模拟这些功能是否可行，并有效地改善鸡的福利。最后，产妇护理的候选人工特征将被推广到商业蛋鸡养殖场，以确定福利效益是否可以大规模复制并持续到生产期结束。该项目不仅将为鸟类的母性行为提供基本的新见解，而且将产生实用和有效的动物福利解决方案; BBSRC的战略优先事项。
