In 2011, 697 million chicks and turkey poults were placed for production in Canada, while 680 million chickens and turkeys were sold to processors that year. These numbers equate to a national culling and mortality rate of 2.42% (17 million birds). Although no data exists on the proportion of morbidities versus mortalities and practices will vary widely between farms dependent on management strategies, it is safe to assume that, under normal production conditions with no epidemic disease pressures, millions of birds annually need to be euthanized on-farm to prevent further suffering. However, there is little scientific data on the best manner by which to euthanize birds of different weights and ages. Building on our expertise, our experienced team of scientists from across North America will study the efficacies of three non-penetrating captive bolt devices, two commercially available mechanical cervical dislocating devices, and different concentrations of carbon dioxide gas for inducing rapid loss of consciousness and death in cull broilers, breeders, laying hens and turkeys in different weight classes, from day-old until end of production. We will utilize behavioural and physical measures of insensibility, post-mortem measures of traumatic brain, skull, vertebral and spinal cord injury, and when possible, brain activity as determined by EEG. This project will result in science-based recommendations on best practices to ensure euthanasia devices are humane, effective and pose minimal threat to the operators.

2011年，在加拿大，有6.97亿只小鸡和土耳其的盗窃者在加拿大生产，而当年有6.8亿只鸡和火鸡出售给了加工商。这些数字等于全国淘汰和死亡率为2.42％（1700万只鸟）。尽管没有关于病态与死亡率和实践比例的数据在依赖管理策略的农场之间会有所不同，但是可以肯定地假设，在没有流行病压力的正常生产条件下，每年需要数百万只鸟类在农场中进行安乐死，以防止农场进一步遭受进一步的痛苦。但是，几乎没有关于最佳方式的科学数据，使不同体重和年龄的鸟类实施。在我们的专业知识的基础上，我们经验丰富的科学家团队将研究三个非穿透圈养螺栓设备的功效，两个商业上可用的机械宫颈脱位设备以及不同浓度的二氧化碳气体，以诱导cull肉，饲养者，饲养犬和土耳其人的生产，直至不同的体重，直至造成库尔犬的意识和死亡的快速丧失，直至不同的重量，直到最终的生产。我们将利用不敏感性的行为和物理量度，外伤后的尸体衡量标准，头骨，椎骨和脊髓损伤，并在可能的情况下，由EEG确定。该项目将对最佳实践提出基于科学的建议，以确保安乐死设备是人道，有效和对操作员构成最小威胁。
