| description |
The aim of the study was to evaluate the variability of the percentage of medullated fibres, according to sex and location and to compare the colorimetric characteristics in white fibre from Huacaya and Suri alpaca. The study was carried out in two communities (Juntaya in the Oropesa district and San Juan in the Sabaino district) in the province of Antabamba, Apurímac region (Peru), located between 3950 and 4543 meters above sea level. In total, 451 (Huacaya = 410 and Suri = 41) fibre samples (10 g) were taken from the mid side area. The medullated fibres (%) and the mean fibre diameter (µm) were evaluated using the Fiber Med device. For the colour analysis, a spectrometer coupled to an integrating sphere was used and for the characterization of the chemical bands, an FTIR spectrophotometer. The percentage of total medullation, continuous medullation and strongly medullated fibres were greater in female Huacaya alpacas (p<0.01). The mean diameter of medullated and non-medullated fibres differed depending on the location, while the mean fibre diameter and mean diameter of medullated fibres were higher in males (p<0.01). The colorimetric parameters of luminosity (L*), chromaticity (C*) and tone (Hº) were similar (p>0.05) in the fibres of the two groups of alpacas. In conclusion, in Huacaya alpaca there is variability in the percentage of continuous medullation and mean fibre diameter, depending on sex and location, but the colorimetric characteristics of white fibres are like those of the Suri. |

El estudio se realizó en dos Comunidades (Juntaya del distrito de Oropesa y San Juan del distrito de Sabaino) de la provincia de Antabamba, región de Apurímac (Perú), ubicados entre 3950 y 4543 msnm. Se tomaron 451 (Huacaya= 410 y Suri = 41) muestras de fibra (10 g), del costillar medio. Las fibras meduladas (%) y el diámetro medio de fibra – DMF (µm) fueron evaluados usando el equipo Fiber Med. Para el análisis de color se utilizó un espectrómetro acoplado a una esfera de integración y para la caracterización de las bandas químicas se utilizó un espectrofotómetro FTIR. El porcentaje de medulación total, medulación continua y de fibras fuertemente meduladas fueron mayores en alpaca Huacaya hembras respecto a machos (p<0.01). El DMF meduladas y no meduladas fueron diferentes según el lugar de procedencia; en tanto que el DMF y el diámetro medio de fibras meduladas fueron supriores en machos (p<0.01). Los parámetros colorimétricos de luminosidad (L*), cromaticidad (C*) y la tonalidad (Hº) resultaron similares (p>0.05) en las fibras de los dos grupos de alpacas. En conclusión, en la alpaca Huacaya existe variabilidad del porcentaje de medulación continua y DMF, según sexo y lugar de procedencia, pero las características colorimétricas de fibras blancas son similares a las del Suri.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2024-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/2877810.15381/rivep.v35i4.28778Revista de Investigaciones Veterinarias del Perú; Vol. 35 No. 4 (2024); e28778Revista de Investigaciones Veterinarias del Perú; Vol. 35 Núm. 4 (2024); e287781682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/28778/21316Derechos de autor 2024 Franklin Lozano, Virgilio Machaca, Jesús Roldan-Juarez, Rubén Pinareshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:revistasinvestigacion.unmsm.edu.pe:article/287782024-08-31T05:05:03Z |
