INSTITUTO DE INVESTIGACION EN CIENCIA ANIMAL Y TECNOLOGIA (IICAT). Determination of nutritional value of native prairie José Manuel Pando Province, Municipality of Santiago de Machaca. J.Selva Andina Anim. Sci. [online]. 2015, vol.2, n.1, pp. 22-33. ISSN 2311-2581.

This research work was conducted in the municipality of Santiago de Machaca which is the first section of the province, José Manuel Pando, it is located at the southeast of the Department of La Paz, at a distance of 205 km, from the city of La Paz. The objectives of this research were to: determine the biomass and floristic composition according to vegetative site, the stocking of native grasslands and the chemical composition of native prairie. The results were the following: the biomass composition and floristic composition is diverse, (35) native forrage species were identified in the vegetative site pampa, Marsh (11), hillside (18) and Hill (33). The capacity of stocking ability of (DC a) stocking of native grasslands, Urtica flabellata (Itapallu) (2.46); Bromus catharticus (bromus) (1.26); Trifolium pratensis (Layulayu) (1.38); Iberis sp. (tears of Virgin) (1.55) and Hordium muticum (tail of mouse) (1.64). Regarding chemical composition, the forage species with higher crude protein content of (%) is  Urtica flabellata (Itapallu), Bromus catharticus (bromus), 181,66 is 25.77%, forage species with higher energy content Kcal100/g Kcal100/g. and forage specie with higher content of iron mg / 100 g was Iberis sp. (Tears of Virgin), 20,97 mg / 100g. These identified species should be preserved and disseminated, since they showed greater amount of production and quality in content of nutrients required by animals. The conservation of these native species identified improve  weight gain, consumption of native forage throughout the year, the chemical content, these native species studied, improve quality and cover the requirements from consumption of dry matter and nutrients required by animals. Finally this condition will positively affect the economy of the producers. It is recommended that these native species should be preserved and disseminated on the Prairies, since they showed greater amount of production and quality in content of nutrients required by animals.
