Validating Ultra-Wideband Positioning System for Precision Cow Tracking in a Commercial Free-Stall Barn

Area of Science:

• Animal Science
• Agricultural Engineering
• Technology in Agriculture

Background:

• Precision monitoring of dairy cow behavior is crucial for welfare and productivity.
• Ultra-Wideband (UWB) positioning systems offer potential for detailed behavioral analysis.
• Validation of UWB systems in complex commercial barn environments is needed.

Purpose of the Study:

• To evaluate the performance of the TrackLab 2.13 UWB system in a commercial dairy barn.
• To assess stationary and moving tag positioning accuracy and reliability.
• To determine the system's effectiveness for proximity detection in a livestock setting.

Main Methods:

• Assessed stationary tag positioning over seven days with ten fixed tags.
• Evaluated proximity detection between eight cows and ten stationary tags.
• Simulated cow movement using three tags on a stick for moving tag positioning analysis.

Main Results:

• Stationary tag reliability varied from 4.09% to 96.73%, with mean accuracy of 0.126 ± 0.278 m.
• Post-software update, only 0.62% of measures exceeded the 0.30 m accuracy specification.
• Proximity detection accuracy within a 2-m range was 81.42% for moving cows.
• Observed spatial variations in accuracy and reliability, especially near barn perimeters.

Conclusions:

• The UWB system demonstrates potential for precision livestock farming and welfare assessment.
• System performance is influenced by tag location and requires careful setup.
• Regular software updates and context-aware data interpretation are essential for optimal use in commercial settings.
