Due to their private habits, the mating period of this species is not known. However, it is well known that most births occur from October to May, the months of heaviest rainfall. Gestation period is estimated to be 12-16 months. During the first few days after birth, the young is hidden in dense vegetation near salt licks while the mother browses. After two months, it can be found wandering with its mother. At birth, the newborn is 60 cm high and 90 cm long, weighing approximately 25 kg. The coat of neonates is short, crisp and black, but later becomes long and shaggy. During earlier stages of development, the young may associate with one another, but they eventually become solitary. Weaning takes place at 16-17 months. Interbirth intervals last at least 3-4 years. By 7-8 years of age, the calves have reached sexual maturity.
