OPERATING AND FINANCIAL REVIEW (CONTINUED) 3. Cattle Operations (continued)  Wagyu cattle The drier conditions have meant that the Group faced higher operating expenses, including increased water pumping costs, in the 3 months to 31  March 2013 than in the prior corresponding period due to the earlier start of cattle and cropping operations. Kilograms produced during the 31 March 2013 quarter were 8.5 million down from 11.1 million kilograms produced in the prior corresponding  period. The lower kilograms produced was largely due to the dryer conditions affecting all large trading herds. The herd continued to add value and perform well. External Wagyu sales also proved profitable.
