Silent Herdsman is a monitoring system for cows and heifers based on a neck mounted tag.

Silent Herdsman continually monitors a cow’s activity and automatically detects changes in normal behaviour, indicating patterns related to parturition and oestrus.

[T]he collar triggers an alert to farmers when cows are on heat, providing farmers with advanced knowledge to activate insemination at critical times. This in turn enables them to produce more milk from the impregnated cows and increase their yields from each herd.

The Silent Herdsman triggers its alert via wireless technology to any mobile device such as a farmer’s mobile phone, tablet or laptop.
