There are
several reasons for gelding a male llama that will not be used for
breeding. Primary amongst them is that it eliminates the possibility of
accidental breeding. While it will reduce the aggressiveness of the llama
towards intact males when there are open females nearby, there will not be
large differences in personality as you might find with other species.
Male llamas that are to be used as guard animals for sheep must be gelded
and they should not have been used for breeding prior to having been
gelded.
Gelded llamas
are frequently the first choice for new llama owners because they are
reportedly the easiest to manage.
Normally
gelding should not take place until the llama is at least 18 months of
age, and preferably not until the llama is two or three years old, because
skeletal development may be affected by earlier gelding. The absolute
earliest we will consider gelding a llama is at age two.
