Adult okapi range in weight
from 240 to 300 kg and have shoulder heights of 1.5 to
1.8 meters with females being larger (Nowak, 1983;
Citino, 2006). Giraffes have a characteristic long neck,
which if not controlled acts as a lever arm during induc-tions and recoveries, creating a danger to the giraffe
and/or the support staff. Mal-positioning of the neck
can lead to airway obstruction and/or cramping or focal
myopathies of neck muscles, which can produce fatali-ties
