Breeding occurs throughout the year with two peak periods in summer and fall. During breeding, the dominant, usually solitary, males stay with a receptive female from 1-3 weeks. During this courtship, the pair often chases, clash horns, and vocalize with each other. After mating, the female leaves the bull's territory. The gestation period is around 16 months. The single young weighs around 50 kg and is very active soon after birth. Calves are weaned anywhere from 1-2 years after birth. After about 2-3 years, the female drives the calf away and mates again. Sexual maturity is reached around 6 years in females and 10-12 years in males.
