El propósito de estudio fue evaluar la estrategia adecuada para el control y tratamiento de la sarna (Sarcoptes scabiei var aucheniae) en vicuñas (Vicugna vicugna) de la Reserva Nacional Pampa Galeras Bárbara D‘Achille – Ayacucho. Se realizó dos capturas con la técnica llamado chaccu, siguiendo lineamientos del bienestar animal. Se trasladaron 24 vicuñas con signos clínicos de sarna en un vehículo acondicionado para tal fin. Luego diez días del encierro y a los 14, 48 y 77 días se realizaron raspados profundos de áreas lesionadas de cada uno de los individuos, las muestras fueron procesadas según lo descrito por (Pence & Ueckermann, 2002) y usando un estereoscopio se realizó la identificación de ácaros y huevos de Sarcoptes scabiei. Los individuos fueron clasificados según la intensidad de la sarna en leve, moderada y severa (Beck, 2014, 2020) y se formaron tres grupo...

This study aims to analyze the determinants of cheese production, focusing on Huaytará, Huancavelica. The research, carried out with 31 milk producers during rainy and dry seasons, revealed that 80.6% of the producers are married, suggesting the influence of family stability. In addition, 67.7% are women, indicating their significant participation in the cheese activity. With 41.9% having secondary education, the need to improve technical capacity is highlighted. Although the majority own their own home (96.8%), the low minimum income (S/. 950) raises economic concerns. The average age of 46.42 years indicates considerable experience in the industry. Milk production focuses on cows and goats (45.2%), but only 12.9% are engaged in cheese production. Pasture-based feeding affects milk composition, and 61.3% of producers milk fewer than 10 cows, reflecting low productivity. Cheese producti...

The objective was to compare the dandruff of dirty and washed fleece in topographic regions of the vicuña (Vicugna vicugna mensalis). The sample consisted of 55 fleeces of vicuña fiber and the following steps were taken to obtain the results; the vicuña fleece was divided into 15 uniform quadrants of 40 cm x 40 cm, delimited in a frame of 1.20 m long x 2 m wide, corresponding to different topographic zones of the animal's body. The following are used: AI = right arm, AII = neck, AIII = left arm, BI = right shoulder, BII = withers, BIII = left shoulder, CI = right rib, CII = back, CIII = left rib, DI = right flank, DII = loin, DIII = left flank, EI = right thigh, EII = rump and EIII = left thigh. For unwashed vicuña fiber, the highest percentage of dandruff was identified in the DII sector (10.45%), corresponding to the back, and high ranges in sectors such as EII (8.65%), CII (7.05%)...

The aim of this study was to evaluate the survival rate and growth patterns in five populations of Festuca dolichophylla under similar conditions. Five accessions were obtained from each population: Comunidad Campesina Pastales Huando – Huancavelica (CCPH), Lachocc South American Camelid Research and Development Center of the National University of Huancavelica (CIDCSL), as well as from the regions of Junín, Pasco and Puno. Each accession was divided into six plants and installed in a uniform CCPH soil. After 12 months of establishment, the survival rate and monthly morphological characteristics during growth were estimated. Survival rates were from 43.3% in CIDCSL plants up to 96.7% in Puno plants (p<0.05) and with high variability within each population. Plant height, growth rate, number of stems, stem appearance rate and number of leaves also showed high variability and differen...
