Abstract
The experiment aimed to assess the nutritional value of the silage Calamagrostis antoniana and Avena sativa in different proportions (treatments): chemical composition in terms of dry matter (%), crude protein (%), crude fiber (%) and intake voluntary (gr.MS / day) in alpaca tuis lower in 6 treatments: T1 (100% Calamagrostis antoniana T2 (80% and 20% Calamagrostis antoniana and Avena sativa ), T3 (60% Calamagrostis antoniana and 40% Avena sativa ), T4 (40% and 60% Calamagrostis antoniana and Avena sativa ), T5 (20% and 80% Calamagrostis antoniana and Avena sativa ) and T6 (100% Avena sativa ). Obtaining microsilos held in silage (4 replicates per treatment). Voluntary intake was assessed in 24 male alpacas, tuis smaller breed huacaya (4 replicates per treatment) for 21 days. The experiment was conducted in a completely randomized design. The Calamagrostis antoniana and Avena sativa silage as associated in different proportions (treatments), varies statistically (p <0.05) in the content of MS (%), PT (%) and FC (%) recorded higher values silage, for T1 (55.60% MS), T6 (11.02% PT) and T1 (33.18% FC). Regarding the voluntary intake of silage and Avena sativa and Calamagrostis antoniana in alpacas, silage that had greater treatment acceptance was T4 and T5, consuming an average of voluntarily: 307.18 and 226.87 (gr. MS / day / animal), respectively.

SUMMARY The experiment aimed to assess the nutritional value of the silage Calamagrostis antoniana and Avena sativa in different proportions: chemical composition in terms of dry matter (%), crude protein (%), crude fiber (%) and intake voluntary in alpaca tuis lower in 6 treatments: T1 (100% Calamagrostis antoniana T2 (80% and 20% Calamagrostis antoniana and Avena sativa), T3 (60% Calamagrostis antoniana and 40% Avena sativa), T4 (40% and 60% Calamagrostis antoniana and Avena sativa), T5 (20% and 80% Calamagrostis antoniana and Avena sativa) and T6 (100% Avena sativa)
Obtaining microsilos held in silage (4 replicates per treatment)
Voluntary intake was assessed in 24 male alpacas, tuis smaller breed huacaya (4 replicates per treatment) for 21 days
Summary
En el presente estudio se realizo en el mes de enero a julio ,ubicado a un nivel de 4350 m.s.n.m , donde se utilizaron 24 alpacas tuis menor de la raza Huacaya que pertenecen al Centro de Investigación y Desarrollo de Camélidos Sudamericanos Lachocc-CIDSL de la Universidad Nacional de Huancavelica-Perú, distribuidos al azar en 24 jaulas individuales de. Los tratamientos fueron sometidos a un proceso de fermentación por 60 días, posteriormente se tomaron muestras para los análisis químicos en el laboratorio de nutrición animal y evaluación de alimentos de la Universidad Nacional de Huancavelica, el análisis de las muestras fueron materia seca(% MS), proteína cruda (% PC), fibra cruda (% FC), el suministro del ensilado fue desde las (08:00 h) hasta las (18:00 h) registrándose diariamente la cantidad rechazada a objeto de evaluar el consumo voluntario (gr.MS/día/animal). Los resultados obtenidos para el análisis químico y consumo voluntario fueron conducidos bajo un diseño completamente aleatorizado, aplicando la prueba de Tukey, al nivel de 5% de probabilidad para analizar las diferencias entre las medias de las variables en estudio
