This research was carried out in the Huancavelica slaughterhouse, located at 3680 meters above sea level. Data were collected from 200 Huacaya alpacas to characterize the carcasses in relation to body weight (BW), hot carcass weight (HCW), cold carcass weight (CCW) and grading meat. BW was 49.5 and 55.6 kg for males and females, and 51.3 and 53.1 kg for 4-tooth and full mouth animals respectively. HCW were 27.3 and 30.0 kg for males and females, and 28.1 and 28.8 kg for 4-tooth and alpaca full mouth respectively. CCW were 26.9 and 29.6 kg for males and females, and 27.7 and 28.4 kg for 4-tooth and alpaca full mouth respectively. Most carcasses were classified as second grade (38.0%) and industrial meat (36.5%) and none was of extra grade. Simple linear equations to predict HCW and CCW from BW showed coefficients of determination of 68.5 and 68.3% respectively. Moreover, highly significan...

El presente trabajo se realizó en el Camal Municipal de Huancavelica, Perú, ubicado a 3680 msnm. Se tomaron datos de 200 alpacas Huacaya con el objetivo de caracterizar las carcasas en función a peso vivo (PV), peso de la carcasa caliente (PCC), peso de carcasa fría (PCF) y grados de clasificación cárnica. Las medias de PV fueron de 49.5 y 55.6 kg para machos y hembras, y 51.3 y 53.1 kg para animales de 4 dientes y boca llena, respectivamente. Las medias de PCC fueron de 27.3 y 30.0 kg para machos y hembras, y 28.1 y 28.8 kg para animales de 4 dientes y boca llena, respectivamente. Las medias de PCF fueron de 26.9 y 29.6 kg para machos y hembras, y de 27.7 y 28.4 kg para alpacas de 4 dientes y boca llena, respectivamente. La mayor parte de las carcasas correspondieron a clasificaciones de segundo grado y tipo industrial (38.0 y 36.5%, respectivamente), no encontrándose carcasas de...

The study aimed to estimate five technological characteristics of the white fibre of Huacaya alpaca of a rural community of the Andean region of Apurimac, Peru. Fibre samples (n=405) were taken from the middle of the rib area prior to shearing. The variables studied were: mean diameter of fibre (MDF), coefficient of variation of fibre diameter (CVDF), comfort index (IC), curvature index (ICur) and spinning fineness (FiHi), by sex and age group according to teeth (DL=Deciduous teeth; 2D=2 permanent teeth; 4D=4 teeth; BLL=all teeth). The MDF for males and females was 19.6 and 20.1 µm respectively (p<0.05), where values increased with age (p<0.05). No statistical difference was found by sex or age for CVDF. The IC was 96.8% in males and 95.5% in females (p<0.05), decreasing with age (p<0.05). The ICur was similar between sexes and difference due to age was only observed between...
