|Demographic||Capture dosages||Tranquillisation dosages|

Body weight: 220–300 kg.
Social behaviour: Breeding herds consist of 5–12 animals, with a dominant bull leading the herd. Roan bulls are not territorial and bachelor herds occur in the area as the breeding group.
Habitat: Open woodland with long grass and enough open water.
Mating season: The whole year.
Calving season: It peaks from August until the peak of the rainy season. A single calf is born after a gestation period of 276–290 days.
General Remarks Relating to Capture
Roan antelope are currently the most highly valued plains game animals in southern Africa owing to their decline in numbers over the years.
These selective feeders are extremely sensitive to habitat change and disturbances, particularly to new development, which they will move away from. They appear not to calve each year, like sable do, which may be a result of nutritional stress during conception owing to their specific requirements.Roan are the largest antelope in southern Africa after eland.
They are extremelyaggressive towards one another and must never be confined together, particularly during capture. This behavior is prevalent amongst all the animals in the herd, even the yearlings to some extent.
Capture needs to be arranged to accommodate the problem of aggression. Roan adults should be transported separately even when tame.Bulls frequently separate from the herd, wandering off alone to return to theherd later.
On small game farms it may be necessary to manage sub-adults separately to ensure that they do not become isolated from supplementary feed and other management facilities.As roan are extremely valuable animals, capture cost is not a major consideration as with other species. Even aerial capture and air lifting of individuals is considered economical. Mass capture combines boma capture with darting.
The herd is caught in the conventional way, much like sable, and boxed between the second and third gates. Thereafter, the animals are individually darted and crated separately. The darting operation should be carried out as soon as possible after capture, from the side or from a blind prepared beforehand inside the boma.
On difficult terrain, consideration should also be given to darting individual animals from the air and cargo slinging them to a central loading point.Tranquillisers should be kept to a minimum as roan, like sable, are very sensitive to them.
