A large calf shed was completed in 2015 on the farm of Hugh Harbison, who farms with the help of his father Thomson, near Aghadowey, Coleraine, Co Derry. A herd of approximately 150 cows begins to calve down in early September. The farm operates a block autumn-calving system, with 75% of cows calving in the first six weeks and all cows calving within 12 weeks.

The shed has the capacity to hold approximately 100 calves at any one time and was designed in-house.
