The Lincoln Longwool is a rare breed of sheep, named after the region, which was developed both for wool and mutton, at least 500 years ago, and has the longest fleece of any sheep breed.[4] The Lincoln Red is an old breed of beef cattle, originating from the county. In the mid 20th century most farms in Lincolnshire moved away from mixed farming to specialise in arable cropping, partly due to cheap wool imports, partly to take advantage of efficiencies of scale and partly because the drier land on the eastern side of England is particularly suitable for arable cropping.[citation needed]
