[Suckling behavior of llamas (Lama glama)].

In the present study the suckling behaviour of six Ilama crias was analysed. A total of 3398 suckling bouts were observed and evaluated. The crias mostly suckled in a reverse parallel position with no side preference. The cria initiated suckling in most suckling bouts whereas the dams usually ended them. The total number of suckling bouts could be divided into two types: suckling bouts of short duration and suckling bouts of long duration. There were no significant differences in duration per suckling bout among the different ages of crias. But the animals suckled less frequently and spent less total time suckling as they grow older. The age related differences and evidence for a dual function (nutrition, social contact) of suckling behaviour are discussed.
