ABSTRACT
Profit per day in the herd was estimated for five Holstein-Friesian x zebu crossbreeding strategies utilizing data from accumulated dairy production of crossbred animals at two levels of management. Sixteen profit functions were generated by all combinations of two levels of: prices for fat and protein, beef value of the animals and price of feed concentrates. Cost-price structure had only small effects on the relative merits of crossbreeding strategies.
