Evaluation of Wearable Cameras for Monitoring and Analyzing Calf Behavior

It’s crucial to know how cattle behave in order to determine their health and management status. Manual livestock observation, on the other hand, is time-consuming and labor-intensive. Furthermore, the presence or position of a human observer during manual observations may affect the cattle’s regular behaviour. Because wearable cameras are small and light, they do not interfere with cow behaviour when connected to their bodies. As a result, the goal of this research was to see how well wearable cameras could be used to monitor and analyse cattle behaviour. From December 18 to 27, 2017, four 2-month-old, group-housed Holstein calves were employed in this investigation at the Obihiro University of Agriculture and Veterinary Medicine’s Field Science Center in Japan. From 10:00 to 15:30, calf behaviour was recorded every 30 seconds using a wearable camera (HX-A1H, Panasonic, Japan) and viewed firsthand between 11:00 and 12:00 and 14:00 and 15:00. The results were compared after the same observer saw the camera recordings corresponding to the direct observation periods. All behavioural data from direct and wearable camera video observations had substantial correlation coefficients (p 0.01). Because the halter extends around the wearable cameras utilised in our investigation, there is a risk of entrapment. As a result, in order to ensure their welfare, calves must be monitored on a frequent basis. Wearable cameras, we conclude, are ideal for watching calf behaviour, particularly posture (standing or laying), rumination, and feeding activities.
