The use of unrelated F1 bulls with the same breed composition in a mating system with cows of the same breeds and fractions (A*B x A*B) will result in a retention of 50% of maximum calf and dam heterosis and an improvement productivity (defined as the increase in weaning weight per cow exposed) of 12%. Finally, crossbreeding can also lead to instability in populations. However, most operations using a crossbreeding system will expand the number of breeding pastures and breeds of bulls.
