The financial profitability of these sheep is dependant on the extra money obtained from the much bigger and more numerous lambs, because the dams clip about 32kg, or $5 worth of wool less than a longwool fleece. Compared with NZ's average Romney producing 4.5kg wool and 1 lamb, the Border Dorsets have produced 3.2kg wool and 1.33 lambs and each carcase weight is 2kg heavier.
