Physical characteristics and fibre diameter profile of Huacaya alpacas from La Raya Experimental Centre (Puno, Peru), according to age and sex
Descripción del Articulo
The technological characteristics and the fibre diameter profile were determined according to age (1, 3, 5, 7 years) and sex (male, female) of Huacaya alpacas from the La Raya Experimental Centre (Puno, Peru). Fleece samples were taken from the middle rib at shearing and analysed with the OFDA 2000...

Physical characteristics and fibre diameter profile of Huacaya alpacas from La Raya Experimental Centre (Puno, Peru), according to age and sexCaracterísticas físicas y perfil de diámetro de fibra de alpacas Huacaya del Centro Experimental La Raya (Puno, Perú), según edad y sexoQuispe Coaquira, Jesús E.Apaza Zúñiga, EdgarOlarte Daza, C. UbertotextilefibreHuacayatextilfibraHuacayaThe technological characteristics and the fibre diameter profile were determined according to age (1, 3, 5, 7 years) and sex (male, female) of Huacaya alpacas from the La Raya Experimental Centre (Puno, Peru). Fleece samples were taken from the middle rib at shearing and analysed with the OFDA 2000 equipment. The data were adjusted to multiple quadratic regression for the analysis of the exchange rates. The average diameter, comfort factor, curvature index and fibre length were statistically similar between sexes, while for age, the diameter increased (from 19.48 ± 0.25 to 24.82 ± 0.80 µm), and both the comfort factor (from 98.15 to 86.95%) and the fibre length (from 102.18 ± 12.92 to 75.00 ± 11.34 mm) decreased, while the curvature index shows no defined trend. The parameters that characterize the fibre diameter profile showed a single maximum value of the mean fibre diameter, which showed a concave curve with two ascending and descending segments. Exchange rates were positive and negative, although their magnitudes were small. It is concluded that the alpacas in the study present their own technological characteristics and the diameter profile configures a characteristic seasonal pattern coinciding with the rainfall seasonality of the Altiplano.Se determinaron las características tecnológicas y el perfil del diámetro de fibra según edad (1, 3, 5 y 7 años) y sexo (macho y hembra) de alpacas Huacaya del Centro Experimental La Raya (Puno, Perú). Se tomaron muestras de vellón del costillar medio al momento de la esquila y se analizaron con el equipo OFDA 2000. Los datos fueron ajustados a regresión múltiple cuadrática para el análisis de las tasas de cambio. El diámetro promedio, factor de confort, índice de curvatura y longitud de fibra fueron estadísticamente similares entre sexos, mientras que para la edad, el diámetro incrementó (de 19.48 ± 0.25 a 24.82 ± 0.80 µm), y disminuyó el factor de confort (de 98.15 a 86.95%) y la longitud de fibra (de 102.18 ± 12.92 a 75.00 ± 11.34 mm), mientras que el índice de curvatura no mostró tendencia definida. Los parámetros que caracterizan el perfil del diámetro de fibra mostraron un solo valor máximo del diámetro medio de fibra, que mostró una curva cóncava con dos segmentos ascendente y descendente. Las tasas de cambio fueron positivas y negativas, aunque sus magnitudes fueron pequeñas. Se concluye que las alpacas del estudio presentan características tecnológicas propias y el perfil del diámetro configura un patrón característico estacional coincidente con la estacionalidad pluvial del Altiplano.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2021-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/2000410.15381/rivep.v32i2.20004Revista de Investigaciones Veterinarias del Perú; Vol 32 No 2 (2021); e20004Revista de Investigaciones Veterinarias del Perú; Vol. 32 Núm. 2 (2021); e200041682-34191609-9117reponame:Revista UNMSM - Revista de Investigaciones Veterinarias del Perúinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/20004/16535Derechos de autor 2021 Jesús E.
