The study was carried out with Creole sheep in flocks from the communities of Cruzpata and Siusay, both in the Lambrama district, Apurímac, Peru. The study aimed to characterize its productive capacity for meat and wool. Samples were taken from 60 sheep from two flocks to determine live weight, carcass weight, carcass yield, fleece weight and lock length. In addition, using 187 sheep from six flocks from the same area, samples of rib wool (10 g) were taken for analysis using OFDA 2000 equipment. The phenotype of the Creole sheep presents an angular body covered with fleece of various colours; bare face, belly and long legs, which grazes the puna, in an extensive system and without technical support from the State. Live weight, carcass weight and carcass yield are low, mainly affected by age, with variations like what occurs in other places in the mountains; Measurements of fleece weight...

El objetivo del estudio fue establecer el perfil de las principales características físicas de la fibra de alpaca que pueden servir para su mejor comercialización y para fines de mejoramiento genético. Se hicieron mediciones de 145 muestras de colores blanco, intermedio y obscuro pertenecientes a alpacas de cinco comunidades del distrito de Cotaruse, Apurímac, Perú, utilizando el equipo ODFA 2000 para determinar el diámetro de fibra (DF), el coeficiente de variación (CV[DF]), el factor de confort (FC) y el índice de curvatura (IC). Se estimaron los efectos de la comunidad, el sexo, edad, color de la fibra y sitio de muestreo sobre el DF, CV(DF), FC e IC y la relación entre ellos. El promedio del diámetro de fibra (MDF) estuvo influenciado por la edad (p<0.01) (valores entre 21.61 y 24.32 ìm), por color de fibra (22.30, 23.81 y 26.69 ìm para blanco, intermedio y obscuro, r...

The objective of the study was to establish the profile of the main physical characteristics of the alpaca fibre that can serve for a better commercialization and for breeding purposes. Measurements were made of 145 white and coloured fibre samples (brown and dark shaded) from five communities of the district of Cotaruse, Apurímac, Peru, using the ODFA 2000 equipment to determine fibre diameter (DF), coefficient of variation (CV[DF]), comfort factor (FC) and curvature index (CI). The effects of community, sex, age, fibre colour and body area of sampling on DF, CV(DF), FC and IC and their relationships were estimated. The mean fibre diameter (MDF) was affected by age (p<0.01) (values between 21.61 and 24.32 μm), by fibre colour (22.30, 23.81 and 26.69 μm for white, brown shaded and dark shaded, respectively) and by community (21.9 μm for Iscahuaca and 24.2 μm for San Miguel de Mes...
