Simple and reliable heat detection

• AiALERT™ Extra is a simple self-adhesive device which is easily attached to the cow to provide effective visual evidence of bulling behaviour

• AiALERT™ Extra detectors contain a pressure-sensitive capsule which is activated by the pressure exerted on the cow by the bulling behaviour of other cows in the herd

• The detector has a built-in time delay mechanism which means it requires approximately 3 seconds of mounting activity before it is activated

• This time delay mechanism helps to distinguish between true standing heat and false mounting activity, so that false positives are avoided
