Ruminant feeding behavior significantly impacts their health and productivity. Traditional methods for monitoring this behavior are often labor-intensive or impractical in free-grazing conditions. This study aimed to develop a low-cost wireless system for this purpose. We designed a system using off-the-shelf components and LoRa technology to acquire single-channel sEMG data from the masseter muscle of ruminant animals. Proof-of-concept testing demonstrated successful system operation in long-distance (simulated) and short-distance (on-animal) scenarios. This system can potentially be a valuable tool for monitoring feeding behavior in free-grazing ruminants. Further research will validate the system’s ability to differentiate between grazing and ruminating activities.

摘要

Ruminant feeding behavior significantly impacts their health and productivity. Traditional methods for monitoring this behavior are often labor-intensive or impractical in free-grazing conditions. This study aimed to develop a low-cost wireless system for this purpose. We designed a system using off-the-shelf components and LoRa technology to acquire single-channel sEMG data from the masseter muscle of ruminant animals. Proof-of-concept testing demonstrated successful system operation in long-distance (simulated) and short-distance (on-animal) scenarios. This system can potentially be a valuable tool for monitoring feeding behavior in free-grazing ruminants. Further research will validate the system’s ability to differentiate between grazing and ruminating activities.
