For their 21st, many girls are happy to receive money, jewellery, possibly a new phone or even for the lucky few, a first car. For Mary Troy, the stand-out present for her on that memorable birthday was none other than a set of calving cameras, gifted to her by an aunt.

Flicking through the screens on her phone, Mary displays the different angles in the shed. Calving is well and truly underway in her dairy herd when Irish Country Living visits the farm in Co Waterford, just a stone’s throw from the Cork border – but firmly of the Déise variety.
