This paper shows the results of several research works on the characteristics of the fleece of vicuñas reared under semi-captivity conditions in the multicommunals of Cala Cala and Picotani, located in the province of San Antonio de Putina, Puno, Peru. The results indicate the presence of three color tones: light, dark and yellowish, whose extension in the body varies according to sex and age. In the praxis only the useful (commercial) part of the coat is sheared. The total weight of fleece shows variations between females (354.71 g) and males (364.65 g) (p<0.05). The fleece yields in vicuñas were similar by sex and body region, while the yield in juveniles was 84.43% and in adults 81.87% (p<0.05). The proportion of clean fleece reaches 80%. The proportion of hair in the fleece shows variations according to sex, age, body region and rearing locality.

El objetivo de esta investigación fue construir un equipo medidor de fibra portátil para uso en el campo; para ello se realizaron diferentes pruebas de medición de muestras de lana de ovino, realizándose para ello pruebas interlaboratorios sobre la precisión del equipo.

The study was conducted in herds of llamas of peasant organizations in the district of Checacupe, Cusco Region, Peru, to determine the biometric measurements and live weight of the Ch’acu llamas based on sex and age. The measurements were grouped in cephalic, heights at withers and rump, cane perimeter and live weight, under a randomized complete design analysis with 2x5 factorial arrangement (α=0.5). Cephalic measurements showed significant differences in favour of the male (p<0.05), but the length of ears was similar; the heights were similar; body length, dorsal length and distance between shoulders favoured females (p<0.05); the measurements of the neck of the male llamas are different (p<0.05), except the length of the neck and its lower perimeter; females exhibit greater thoracic perimeter (p<0.05), but the thoracic perimeter and depth were similar; the thickness of ...

The morphology of 284 K’ara llamas was determined through biometric measurements and body weight based on sex and age factors. The animals were from breeder organizations in the Checacupe district of the Cusco Region, Peru. The measurements were grouped into cephalic, body and trunk heights, cane perimeter and body weight. The analysis was carried out in a 2x5 factorial arrangement (2 sexes, 5 ages) under a complete randomized design. At head level, head length is the only one that contributes to sexual dimorphism (p<0.05). Head height showed greater value, attributable to the presence of an elongated and upright neck. Body lengths show sexual dimorphism and have different growth and development. Male neck measurements were greater (p<0.05), except for the length of the neck. At the thorax level, the thoracic perimeter and depth were greater in males (p<0.05). Each morphologic...

In the Queulla sector, community of Chapimarca, province of Grau, Apurímac Region, the textile properties of the fibre of white Huacaya alpacas were determined, according to factors sex, body region and age group. The fibre analyses were carried out in the Fibre and Wool Laboratory of the National University of Huancavelica. The juvenile alpacas had a smaller fibre diameter (MDF), a higher comfort factor (FC), a higher yarn fineness (SF) and a better curvature index (IC) than the adult ones (p<0.05). Males presented better FC and yarn fineness (SF) than females (p <0.05). In general, the fibre of the rib area and the rump were of similar quality, but superior to the fibre of the shoulder (p<0.05). It is concluded that the fibre produced in the study is within the fibres of good quality.
