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 ...

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.

El descerdado de la fibra disminuye el diámetro medio de la fibra, desviación estándar, coeficiente de variabilidad y aumenta el factor de confort e í...

This review is based on the publication «Definition of breeds of alpacas and llamas», by Animal Genetic Resources journal, which places the alpaca at the primary level in the evolution of domestic animal breeds. and makes a review of the domestication of the alpaca, the treatment received during the conquest and colonialism, the inclusion of the alpaca fibre in the international textile market, the technical management during the Republic until the present, first in large farms (haciendas), then in the associative companies and currently in medium-sized properties and in State institutions and universities. Management testimonies are also presented with figures from some producers and finally the morphological differential characters and the fibre structure that characterizes and defines the Suri and Huacaya breeds.

Five technological characteristics of llama fiber were evaluated: average fibre diameter (AFD), the coefficient of fibre diameter (CVD), the comfort factor (CF), the fibre curvature (FC) and the spinning fineness (SF) before and after dehairing. Fibre samples (10 g) were collected from fleece of 227 llamas Chaku from the Apurimac region of Peru. Fiber samples before and after dehairing were analyzed with the OFDA 2000 (Optical Fibre Diameter Analyser). Sex and age (1-2 years and >2 years old) were considered as variables and the data was analyzed in a randomized complete design with a factorial arrangement. The results showed that dehaired llama fibre showed better quality, less AFD (0.70 μm), CVD (1.8%) and SF (1.06 μm) and better CF (2.74%) and FC (4.66°/mm). Sex had no significant effect on the technological characteristics of the fibre but younger animals had better quality fib...

Se evaluaron cinco características tecnológicas de la fibra de llama: diámetro medio de fibra (MDF), coeficiente de variación de MDF (CVMDF), factor de confort (FC), índice de curvatura (IC) y finura al hilado (FH) antes y después de descerdar. Se tomaron muestras de 10 g de fibra de vellones de 227 llamas Chaku de la región Apurímac, Perú. Las fibras sin descerdar y descerdadas fueron analizadas con el equipo OFDA 2000 (Optical Fibre Diameter Analyser). Se consideraron las variables sexo y edad (1-2, >2 años) en el análisis estadístico a través de un diseño completamente al azar con arreglo factorial.

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...

An environmental enrichment programme was applied to pumas (Pumas concolor) of the Taraccasa Zoological Park in Abancay (Apurímac, Peru) to monitor behavioural changes. Four pumas or cougars (three females, one male) from 3 to 9 years old were observed. Four types of environmental enrichment were used: physical (wooden stools, tree trunks), food (equine meat, balanced feed for cats), sensorial (sacks with aromatic essences and spices, urine of foxes and deer), and social (balls made with equine skin). The study considered the stage prior to environmental enrichment (24 days) and the stage during environmental enrichment (24 days). The behaviours were recorded with video camera between 09:00 to 12:00 and between 16:00 to 18:00. Individual behaviours with a significant increase were body care, locomotion, observation, exploration, search (p<0.001) and reduction of abnormal behaviour su...
