Abstract
Por efectos de la degradación y baja producción de pastos naturales, se presume no se cubren los requerimientos nutricionales de la llama. El objetivo de la investigación fue evaluar la degradabilidad in situ de materia seca (DISMS), de proteína bruta (DISPB), fibra detergente neutra (DISFDN) y fibra detergente ácida (DISFDA), de la dieta seleccionada por llamas según meses y tiempos de incubación, en la comunidad Jila Huta Manasaya, Sajama Oruro. Se seleccionaron 4 llamas machos de 3 años de edad, tipo q'ara de 70 kg/llama; de tamas de la comunidad en los que fueron aplicadas mediante cirugía implante de cánulas en el primer compartimento (C1). Las muestras de ingesta colectada a nivel esofágica de llamas pastoreadas en pastizales naturales fueron secadas, molidas, almacenadas 3 g en bolsas Dacron de 1700 poros/cm2 no digeribles, luego incubadas en el C1 durante 0; 6; 12; 24; 36; 48; 72, y 96 horas en los meses de octubre, noviembre y diciembre. Las técnicas de análisis de laboratorio empleadas son el análisis proximal de Weende y análisis de Van Soest. Los datos fueron analizados con arreglo factorial 3*8 en diseño completamente al azar y las diferencias mediante la prueba de comparación de medias de Duncan. Los resultados obtenidos fue la degradabilidad in situ se da en un proceso y velocidad lento en el primer compartimento del estómago de llamas.
Due to the effects of degradation and low production of natural grasses, it is presumed that the nutritional requirements of the flame are not covered. The objective of the research was to evaluate the in situ degradability of dry matter (DISMS), crude protein (DISPB), neutral detergent fiber (DISFDN) and acid detergent fiber (DISFDA), of the diet selected by flames according to months and times of incubation, in the Jila Huta Manasaya community, Sajama Oruro. Four 3-year-old male llamas, q'ara type of 70 kg / llama, were selected; of community sizes in which they were applied by surgery to implant cannulas in the first compartment (C1). The samples of ingestion collected at the esophageal level of llamas grazed in natural grasslands were dried, ground, stored 3 g in Dacron 1700 pore / cm2 non-digestible bags, then incubated in C1 for 0; 6; 12; 24; 36; 48; 72, and 96 hours in the months of October, November and December. The laboratory analysis techniques used are the proximal Weende analysis and Van Soest analysis. The data were analyzed with a 3 * 8 factorial arrangement in a completely randomized design and the differences using the Duncan mean comparison test. The results obtained were the degradability in situ occurs in a slow process and speed in the first compartment of the llama stomach.
