Estimating forage intake by free-grazing livestock is difficult and expensive. AFSRC scientists developed an acoustic recording and analysis system that automatically detects, classifies, and quantifies ingestive events in free-grazing beef cattle. The system uses a microphone close to the animal’s mouth, mathematical signal analysis to detect and measure ingestive events, and streaming data analysis. Links to a movie and sound file are available at the AFSRC presentations page.

More information about the system is available in the scientific journal Computers and Electronics in Agriculture (Clapham, W. M., J. M. Fedders, K. Beeman, and J. P. S. Neel. 2011. Acoustic Monitoring System to Quantify Ingestive Behavior of Free-Grazing Cattle. Computers and Electronics in Agriculture, 76(1):96-104.)
