The College dairy herd consists of 140 Holstein Friesian cows plus followers, producing 1,000,000 litres of milk per annum.
Further quota is leased in annually if extra production is profitable.
All milk is sold through a local dairy farmer co-operative, North and East Riding Milk Producers, to M D Foods of Leeds. The dairy herd graze the parkland within the shelter belt during the spring, and are reliant on zero grazed grass and kale for the remainder of the grazing season. Winter housing consists of a single span portal framed building with cubicles in four rows, divided by a central feed passage. An adjoining lean-to provides further cubicle space. Considerable time was spent during summer 1998 upgrading cubicles by lengthening them and installing mats.
