| Data of dry matter intake (DMI) individually measured in animals are critical to the feed efficiency (FE) indexes. This information guide the decisions made in breeding programs. Here, the objective was describes the technologies and protocols available to measure the DMI in cattle and the use of these information on genetic evaluations. The electronic identification by radio frequency when coupled with weighing bunks (plus storage of data) can be used for monitoring the DMI throughout the day. When performed at individual pens, the cattle feedlot may change the behavior, performance and, consequently, the FE. Thus, the relevance of data at these housing types can be questioned. Calan-gate is an alternative system for collective pens, however, dominant... |
