Smartbell Ear Tags were applied to 3 separate groups of calves in batches arriving during the autumn, winter and spring. For each batch, a control group arriving at the same time was left untagged. The Smartbell tag provided constant monitoring of the animals and if an anomaly was detected, an alert sent to the calf rearer on their phone prompting early examination for signs of early disease on-set. The Smartbell alerts provided daily guidance and group performance analysis, as well as the early warning alerts.
