Partially derived from the outputs obtained from the DairyICT project, the start-up company Silent Herdsman from the University of Strathclyde, Glasgow, was created. Silent Herdsman is an internet of things (IoT)- inspired decision support platform that supports the optimisation of animal husbandry within dairy farms and in turn maximises productivity (milk production, milk quality, health) and welfare. Silent Herdsman developed a tracking system consisting of a neck-mounted collar, which is very accurate, and highly scalable. In 2016, the company Afimilk Ltd (a global leader in farm management software and milk analysis tools for dairy operations in 50 countries) acquired the neck collar developed by Silent Herdsman. The collar allows the tracking of each cow individually and provides alerts related to changes associated with the onset of heat and/or the health of the animal in real time. By analysing the time spent eating and ruminating behaviour patterns for individual animals, Silent Herdsman also provides early indications of illness. The deployment of the collars has proven to decrease the calving index (CI) from 40 days (for poorly performing farms) to 20 days (for high-performing farms). For example, on a UK farm, collar deployment has yielded a 40-day improvement in the CI for a 500-cow herd, which translates to >£100k additional revenue and represents a return on investment within seven months.
