Various What Are Activity Monitors for Dairy Cows?

Activity monitors are electronic devices worn by dairy cows—typically on leg or neck—that measure movement, rumination, and behavior patterns to detect...
Activity monitoring has transformed reproductive management and health detection on dairy farms. By tracking behavior continuously, these systems detect changes humans would miss—catching more heats, earlier, and alerting to health problems before production drops.
Most systems measure activity (steps, motion), rumination (jaw movements), and eating time through accelerometers and microphones in tags worn on neck or leg. Advanced systems add lying time, location tracking, and even temperature sensing. Data transmits to base stations and management software.
Heat detection is the primary ROI driver for most operations. The distinctive activity spike (300-400% above baseline) reliably indicates estrus. Systems provide optimal insemination timing recommendations, improving conception rates while eliminating missed heats.
Health monitoring has become equally valuable. Drops in activity, rumination, or eating often precede clinical disease by 1-3 days. Fresh cow monitoring catches displaced abomasums, metritis, and ketosis earlier. Group-level changes may indicate ration problems or environmental stress.
Integration with herd management software creates powerful management systems. Activity data combines with reproduction, health, and production records for comprehensive cow management. Attention lists prioritize animals needing intervention.
System selection involves considering coverage (all cows or targeted groups), tag location (neck vs. leg), parameter depth (activity only vs. full behavior), and integration requirements. Costs range from $70-$200+ per tag plus infrastructure.
