In the United States, empirical information on the sustainability of commercial-scale egg production is lacking. The passage of state regulations specific to hen housing created urgency to better understand the effects of different housing systems on the sustainability of the egg supply, and stimulated the formation of a coalition, the Coalition for a Sustainable Egg Supply (CSES), to conduct research on this topic. The CSES is a multi-stakeholder group with 27 members, including food manufacturers, research institutions, scientists, restaurants, food service, retail food companies, egg suppliers, and nongovernmental organizations. A commercial-scale study was developed to better understand the effect of 3 housing systems (conventional cage, enriched colony, and cage-free aviary) on 5 areas related to a sustainable egg supply. These 5 sustainability areas represent effects on people, animals, and the environment: animal health and well-being, environment, food safety, worker health and safety, and food affordability. Five teams of scientists, each associated with a sustainability area, conducted an integrated field study at a commercial site in the upper Midwest through 2 flock cycles in 3 housing systems. This paper provides a brief overview of the CSES project to serve as an introduction for the papers that follow in this volume of Poultry Science.
在美国，缺乏关于商业规模鸡蛋生产可持续性的实证信息。针对母鸡饲养的州法规的通过，促使人们迫切需要更好地了解不同饲养系统对鸡蛋供应可持续性的影响，并刺激了一个联盟——可持续鸡蛋供应联盟（CSES）的形成，以对这一主题进行研究。CSES是一个拥有27名成员的多利益相关方团体，成员包括食品制造商、研究机构、科学家、餐馆、食品服务公司、零售食品公司、鸡蛋供应商和非政府组织。开展了一项商业规模的研究，以更好地了解三种饲养系统（传统笼养、富集型群体饲养和无笼舍饲养）对与可持续鸡蛋供应相关的五个领域的影响。这五个可持续性领域代表了对人（类）、动物和环境的影响：动物健康与福利、环境、食品安全、工人健康与安全以及食品可负担性。五组科学家，每组负责一个可持续性领域，在中西部上游地区的一个商业场地，通过三个饲养系统中的两个鸡群周期，开展了一项综合实地研究。本文简要概述了CSES项目，作为本卷《家禽科学》后续论文的引言。
