Research on the growth potential of three crossbreeds between Charolais, Red Angus and Droughtmaster bulls with Brahman crossbred female from birth to 21^st  month of age reared in Hanoi, Hung Yen and Thai Nguyen. The results of monitoring 60 crossbred cows (20 heads/crossbred) showed that the average weight of the Charolais and Red Angus combination was higher than that of the Droughtmaster cross (P<0.05) at the age milestones from birth to birth 21^st  month of age. At 21^st month of age, the weight of the Charolais × Brahman crossbred female combination was the highest (478.9 kg), followed by the Red Angus × Brahman Brahman crossbred female combination (451.2 kg) and the lowest was the Droughtmaster × Brahman crossbred female combination (410.7 kg). The ability to increase weight of crossbred cows from birth to 21^st month of age of the Charolais and Red Angus crosses was higher than that of the Droughtmaster combination (P<0.05) respectively reaching 710.9; 669.5 and 608.1 g/head/day.
