The current and future research topics in dairy cattle breeding aim at gaining scientific knowledge in the field of resource efficiency, environmental relevance, understanding the physiological relationships, animal health and animal welfare. For knowledge-based approaches to clarify these complex questions, the continuous measurement of individual animal feed intake is an absolutely essential prerequisite. The implementation of a measuring platform for feed intake by dairy cows is planned in the newly built dairy cattle barn at the research farm of Kiel University in Karkendamm, which is in charge of the Institute for Animal Breeding and Husbandry. The device configuration ensures the recording of time points, the duration and the amount of feed taken up for each individual feeding process of a dairy cow at the respective feed trough. For this purpose, the specially manufactured feed troughs are equipped with weighing devices consisting of load cells and detection electronics, which in turn are electronically connected to a central unit. The identification of the individual animal takes place via RFID (radio-frequency identification) transponders; this means that each eating process can be assigned to a specific animal. The amount of fresh feed taken up is calculated from the weight difference between the contents of a weighing trough before and after the animal’s visit. This information is transmitted to the central unit together with the animal identification. All individual feeding processes are saved chronologically and aggregated into daily values ​​via the various weighing troughs visited. Regular feed analyzes and standardized feed drying procedures, which are partly carried out at the farm allow to determine the dry matter intake for each individual animal. Based on this, the data collected by the device together with data routinely recorded on the farm (milk quantities, milk ingredients) can be used to determine the energy balance, feed and nitrogen efficiencies at the individual animal or herd level. The central unit on the farm is connected to the institute's own database via a dedicated line and automated data transmission is once daily. For specific scientific questions, the animal-specific information can be linked with e.g. genotyping results or physiological parameters and evaluated integrally.The system is integrated into the normal process of dairy cattle feeding and the troughs are filled, cleaned and maintained by the employees of the farm. All responsible researchers have free access to the device; all other users have access to the institute's own data base at the computing center in order to use the measurement data.

奶牛育种当前和未来的研究主题旨在获得资源效率，环境相关性，了解生理关系，动物健康和动物福利领域的科学知识。对于基于知识的方法来澄清这些复杂的问题，连续测量个体动物的摄食量是绝对必要的先决条件。计划在Karkendamm的基尔大学研究农场新建的奶牛畜棚中实施奶牛采食量测量平台，该研究所负责动物育种和畜牧业研究所。该设备配置确保记录奶牛在相应饲料槽处的每个单独饲喂过程的时间点、持续时间和采食量。为此，专门制造的饲料槽配备有称重装置，包括称重传感器和检测电子设备，这些称重装置又与中央单元电子连接。通过RFID（射频识别）应答器识别个体动物;这意味着每个进食过程都可以分配给特定的动物。根据动物访视前后称重槽内容物之间的重量差计算摄取的新鲜饲料量。该信息与动物标识一起被传输到中央单元。所有单个喂养过程按时间顺序保存并汇总为每日值 通过访问的各种称重槽。定期的饲料分析和标准化的饲料干燥程序（部分在农场进行）可以确定每只动物的干物质摄入量。在此基础上，该设备收集的数据以及农场常规记录的数据（奶量、奶成分）可用于确定个体动物或牛群水平的能量平衡、饲料和氮效率。农场的中央单元通过专用线路连接到研究所自己的数据库，每天自动传输一次数据。对于特定的科学问题，动物特定的信息可以与基因分型结果或生理参数相关联，并进行整体评估。该系统集成到奶牛饲养的正常过程中，由农场员工填充，清洁和维护槽。所有负责的研究人员都可以自由使用该设备;所有其他用户都可以访问该研究所在计算中心的数据库，以使用测量数据。
