Whether it’s dairy, sucklers or sheep, a farmer’s fondness for a particular breed can often be let override profit from their system of farming. The animals in all these livestock-dependent businesses are the engine for producing profit. On page 45, Darren Carty profiles how a young hill sheep farmer is making changes to manage the resources available to him by modifying his breed to suit a less intensive hill-grazing business. His realisation that he was carrying all the costs of a lowland system while not achieving lowland output is a game-changer. His new plan better matches farm resources and the business making a return. There are lessons for all – not just the hill sheep farmers.
