The llama (lama glama) in the Bolivian Highlands region is a most important potential resource from the socio-economic point of view for the dedicated producer to the management and exploitation of these Andean camelids, considered as national heritage of our country. The llama is completely adapted to the high plateau system, being considered a three purposed animal in this environment: producer of fiber, meat and work (load). However, due to the expansion of sheep and cattle, they have been marginalized to the poor areas, where they prosper well because they are rustic, sober and greatly efficient in the conversion of food and resistance to the weather of the ecological environment of the Andes. The overuse of pastures, due to the increasing number of heads, has caused imbalance, as the burden of the animal is greater than the load capacity of the native prairie. This translates to the dietary deficiency that affects the rate of fertility, birth, fiber production, meat production and others. The llama is characterized by its great capacity to take advantage of the native grasses, which do not have any studies on the degradability in different seasons and the grade of degradability of forage consumed in different fermentation times in the first compartment of the stomach. Therefore, this work of research, through its results, will create the implementation of conservation programs, improvement and implementation of native grasslands and cultivated to meet the nutritional needs of the llama. In the present work, the degradability of forages from the native prairies, for llamas in the rain season, has been planted to know to determine how long it takes to produce maximum degradability and know in what percentage the nutrients are utilized. With the results, programs can be developed to determine whether or not there is an unmet demand for nutrients.
