	abstract = {Stocking rates for maximum production and economic performance  of Holstein-Friesians and Jerseys were predicted by calculating response  curves from the regression equations of stocking rate on cow  performance. Holstein-Friesians produced higher yields, gross milk  incomes and net incomes per cow while Jerseys produced higher milkfat  and protein yields, gross milk incomes and net incomes per ha when both  breeds were stocked at the same liveweight or for maximum production or  optimum economic performance. Maximum net income based on 1990/91 costs  and prices occurred at 3.0 and 3.7 cows/ha for Holstein-Friesians and  Jerseys respectively. At these stocking rates net income for Jerseys  was 5\% higher than for Holstein-Friesians.  },
