Determinación del valor nutricional de la pradera nativa provincia José Manuel Pando Municipio de Santiago de Machaca
Abstract
El presente trabajo de investigación fue realizado en el municipio de Santiago de Machaca es la primera sección de la provincia José Manuel Pando, se encuentra al Sureste del Departamento de La Paz, a una distancia de 205 km, de la ciudad de La Paz, los objetivos de la investigación fueron: Determinar la biomasa y composición florística según sitio vegetativo, la capacidad de carga animal de pastizales nativos y la composición química de la pradera nativa, los resultados fueron los siguientes: La composición biomasa y composición florística es diversa, se identificó (35) especies forrajeras nativas en el sitio vegetativo pampa, bofedal (11), ladera (18) y cerro (33). La capacidad de carga animal (C.C.A) de los pastizales nativos, Urtica flabellata (Itapallu) (2,46); Bromus atharticus (Cebadilla) (1,26); Trifolium pratensis (Layulayu) (1,38); Iberi ssp. (Lágrimas de virgen) (1,55) y Hordium muticum (Cola de ratón) (1.64), respecto a composición química, la especie forrajera con mayor contenido de proteína cruda (%) es de Urtica flabellata (Itapallu), 25,77%, la especie forrajera con mayor contenido de valor energético Kcal100/g es de Bromus catharticus (Cebadilla), 181,66 Kcal100/g. y la especie forrajera con mayor contenido de hierro mg/100g es de Iberis sp. (Lágrimas de virgen), 20,97 mg/100g. Estas especies identificadas deben ser conservadas y difundidas, debido a que mostraron mayor cantidad de producción y calidad en cuanto a su contenido de nutrientes requeridos por los animales. La conservación de estas especies nativas identificadas favorecerán a mejorar en la ganancia de peso, consumo de forraje nativo a lo largo del año, el contenido químico de estas especies nativas estudiadas, mejoran la calidad y cubren los requerimientos de consumo de materia seca y nutrientes requeridos por los animales. Finalmente esta condición incidirá positivamente en la economía de los productores. Se recomienda que estas especies nativas deban ser conservadas y difundidas en las praderas, debido a que mostraron mayor cantidad de producción y calidad en contenidos de nutrientes requeridos por los animales.
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.
