Due to increasing public concern regarding separation of the dairy cow and calf within the first days after birth, alternative systems, where cows and calves stay in contact for an extended period, are receiving increasing interest from a broad array of researchers and other stakeholders. With more research in the area, there is a risk of inconsistencies emerging in the use of terminology. To create a better consensus in further discussions, the aim of this Research Reflection is to provide definitions and propose a common terminology for cow-calf contact in dairy production. We also suggest definitions for various systems allowing cow-calf contact and describe the distinct phases of cow-calf contact systems.

牛犊接触系统研究和讨论的方法学术语和定义

由于公众越来越关注奶牛和小牛出生后头几天的分离，奶牛和小牛长时间保持接触的替代系统越来越受到广泛研究人员和其他利益相关者的关注。随着该领域的研究越来越多，术语的使用可能会出现不一致的情况。为了在进一步的讨论中达成更好的共识，本研究反思的目的是为奶制品生产中的牛-小牛接触提供定义并提出一个通用术语。我们还建议定义允许牛-小牛接触的各种系统，并描述牛-小牛接触系统的不同阶段。
