Alpacas are generally shorn annually in springtime when the
weather is warm. Most alpacas are shorn by lying them down on
the shearing board and restraining them in a rope harness, or
prone on the ground. This may look unusual but ensures that the
animal is kept as still as possible, to be shorn with the minimum
of fuss and without undue stress. Females are usually shorn between
birthing and mating or between 6 and 45 weeks of gestation, thus
avoiding the periods when the foetus is most vulnerable.
