Mating takes place between August and November. It is unknown if saola exhibit any mating rituals.
There is little information available on the mating systems of saola, but estimations were made from examining a dead pregnant female. Saola give birth between April and June. It is not known whether saola use their horns as display for mating purposes. They are similar to other Bovinae, like four-horned antelope, in that gestation lasts 8 months. Saola only have one offspring per litter.
Other information on reproduction in this species is not available. These animals were only recently recognized as a species, and are quite rare.
Breeding interval: Saloa appear to breed once per year.
Breeding season: Breeding apparently takes place between August and November.
Range number of offspring: 1 (low) .
Average number of offspring: 1.
Average gestation period: 8 months.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (Internal ); viviparous
There is little information available on parental investment of saola, although Artiodactyl young are generally precocious. Like other members of the family, it is likely that most parental care is provided by the mother. Young receive nourishment from mother's milk, protection from mother, and probably some form of grooming. It has not been reported how long young are dependent upon the mother, although if soloa are like other members of the family, it is likely to be around one year.
Parental Investment: pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female)
