Nyala
(Tragelaphus angasi)
Introduction
Nyala bulls are grey in colour weighing an average of
108kg and standing 1.1m tall, the young bulls are a
rusty red colour and changes grey once they become
sexually mature. The ewes remain the same rusty-
red colour with an average weight of 62kg and 0.97m
height. The stripes that are seen on the young will
disappear with age. Young bulls can be identified by
the white dorsal crest even before the horn buds can
be seen. 1,2
Habitat
Nyala are commonly found in and around riverine
areas and dry woodlands. They prefer dense tickets as
a hiding place when disturbed. The also take shelter in
dense bush to shelter from rain and cold. 1
Behavior
The are found in small groups from 2-3 usually
consisting of a adult ewe and her young. Feeding
leaves, twigs flowers, lush green grass and fruits. They
can be found in larger groups around water holes and
preferred areas. Ewes can be seen separate when
having a young lamb. This lamb joins the group from
about 18 days onwards. 1
Reproduction
Lambing peaks in August to September after a 200 day
gestation period and again in May. In intensive systems
a 3 lambs per 2 year cycle can be expected. 1,2

Darting
Low impact systems are crucial when darting young
animals. Although the adults have very tough skin.
Young animals can easily be injured and especially
the perineal area are delicate in adults as well. Using
a Motsumi Darts, Tel-Inject or Dan-Inject system
with 3/4” needles and 1/2” needles in young animals
works well. Telemetry or (Transmitter) darts can be
considered in areas of dense bush. Limitation due
to the distance these darts can be shot should be
considered and a careful on road approach should
be followed. Placement only in the hind quarters
with telemetry darts. Using a 3/4” or 1” double-
barb system. 1,2 Be careful with placing darts in the
thoracic region. Even with short needles it is possible
to puncture a lung. Only short range shot should be
attempted at the supra-spinatus/neck area. Do not
attempt to dart trough brush. Placement of dart may
be severely affected.
