Abstract: In one or more arrangements, a system for tracking, coordination, and/or control of livestock birthing operations is presented. In one or more arrangements the system includes a backend system and one or more personal electronic devices communicatively connected to the backend system. The personal electronic devices are configured to provide a user interface for workers to monitor and update information for a set of farrowing livestock animals in the backend system. In one or more arrangements, the system provides a platform implemented by operations coordination software on the backend system and the user interface on the personal electronic devices. The platform is designed to serve as the epicenter of day-to-day operations in livestock operations, tracking and providing critical information about employee performance, animal health, animal production, and link with and/or control performance of automated agricultural equipment and/or third-party technologies.
