El estudio, cuyo objetivo fue determinar el efecto de la suplementación de aminoácidos sobre el índice folicular y las características textiles de la fibra de alpaca, se llevó a cabo en el Centro de Investigación y Desarrollo de Camélidos Sudamericanos – Lachocc, perteneciente a la Universidad Nacional de Huancavelica. Para ello, se utilizaron 44 alpacas Huacaya entre machos y hembras nacidas el año 2017, las cuales se desparasitaron 10 días antes del inicio del experimento, las mismas fueron distribuidas en dos tratamientos: T1 (testigo) a los cuales se les aplicó 3 ml de suero fisiológico por cada 5 kg de peso vivo, y T2, quienes recibieron 3 ml de aminoplex por cada 5 kg de peso vivo. Los tratamientos fueron aplicados vía intraperitoneal, cada 15 días desde enero a julio del 2018. Las muestras de fibra fueron obtenidas del costillar medio derecho de cada alpaca por medi...

The aim of this study was to determine the degradability of the association of forages and crop residues commonly used to feed cattle in the Huancavelica Region. The forage associations were white clover-Italian ryegrass and red clover-dactylis, while the harvest residues were maize, oat straw, peas, beans and quinoa. For the determination of the degradability of dry matter (DM), crude protein (CP) and neutral detergent fibre (NDF), three rumen fistulated Brown Swiss cattle were used. Samples of forages and harvest residues were placed in nylon bags and incubated for 4, 8, 12, 24, 48, 72 and 96 hours. Time zero (t0) was used for the calculation of the soluble fraction. The DM, CP and NDF degradability were influenced by forages and crop residues (p<0.05). The greater potential degradability of the DM and CP, and effective degradability of the DM, CP and NDF give the white clover-Itali...

This research was serialized in the Laboratory of Animal Nutrition and Food Evaluation (LUNEA) of the Professional School of Zootechnics of the National University of Huancavelica, Peru, with the objective of estimating the consumption of forage barley silage with levels of potato foliage (Solanum tuberosum) and wheat bran from neutral detergent fiber. Forage barley samples with a chopped size of 4 to 6 cm were used, where potato foliage and wheat bran were added at different levels 0, 10, 20 and 30%. The chopped material was ensiled in bag-type mini-silos with a capacity of 5 kg for 30 days. After the fermentation time, the mini-silos were opened and samples were taken to evaluate the neutral detergent fiber and apply the prediction equation for consumption. of dry matter (CMS). An analysis of variance was used for the variables under study. The %FND was in the range of 47.29±4.03% to ...
