The social and political pressure to change egg production from conventional cage systems to alternative systems has been largely driven by the desire to provide more behavioral freedom for egg-laying hens. However, a change of this magnitude can affect other components of the production system and may result in unintended outcomes. To understand this issue, a Socially Sustainable Egg Production project was formed to 1) conduct a holistic and integrated systematic review of the current state of knowledge about various aspects of sustainable egg production, and 2) develop a coordinated grant proposal for future extramural funding based on the research priorities identified from the review. Expert study groups were formed to write evidence-based papers in 5 critical sustainability areas: hen health and welfare, economics, food safety and quality, public attitudes, and environmental impacts. These papers were presented as the PSA Emerging Issues Symposium on Social Sustainability of Egg Production at the 2010 Poultry Science Association meeting.
将蛋鸡生产从传统笼养系统转变为其他系统的社会和政治压力，很大程度上是由为产蛋母鸡提供更多行为自由的愿望所驱动的。然而，如此大规模的变革可能会影响生产系统的其他组成部分，并可能导致意外后果。为了解决这个问题，一个社会可持续蛋鸡生产项目应运而生，其目的是：1）对可持续蛋鸡生产各方面的现有知识状况进行全面、综合的系统综述；2）根据综述确定的研究重点，制定一份协调一致的未来校外资金资助申请提案。成立了专家研究小组，就5个关键的可持续性领域撰写基于证据的论文：母鸡健康与福利、经济学、食品安全与质量、公众态度以及环境影响。这些论文在2010年家禽科学协会会议上作为蛋鸡生产社会可持续性的PSA新问题研讨会发表。
