| description |
To identify variations in fibre diameter in the type of medullation in Huacaya alpacas from the La Raya Experimental Centre, Puno; 6 g of fibre from the left side of the middle ribcage of 190 alpacas were collected, considering the factor sex (males: 89; females: 109) and age group (I: 1-2; II: 3-4; III: 5-6). ; IV: 7-8; V: 9-10 years). The variables considered included non-medullated fibres, with fragmented medulla, continuous medulla, discontinuous medulla and strongly medullated fibres with their respective percentages. The fibres were analysed using FIBER MED equipment and the evaluation of the percentages were subjected to Bliss angular transformation to obtain arcsine values. A 2x5 factorial arrangement was used under a completely randomized design. Also, Spearman correlation was determined. The average fibre diameter (AFD) increased with age (p<0.05). The percentage of total medullated fibres (TPM) increased from 34.79% in the 1-2 years group to 74.72% at 9-10 years (p<0.05) and the percentage of non-medullated fibres (NFM) decreased from 65.69 to 25.60% (p<0.05). The most notable correlations were between TMP and AFD (r=0.883) and between FNM and AFD (r=-0.883). It is concluded that in Huacaya alpacas the diameter of medullated fibres is greater than that of non-medullated fibres, whereas the percentages of medullated fibres are greater than those of non-medullated fibres. |

Las variables consideradas incluyeron fibras no meduladas, con medula fragmentada, medula continua, medula discontinua y fuertemente meduladas con sus respectivos porcentajes. Las fibras fueron analizadas utilizando el equipo FIBER MED y la evaluación de los porcentajes fue previa transformación angular Bliss a valores enteros arcoseno. Se utilizó un arreglo factorial 2x5 bajo un diseño completamente al azar. Asimismo, se determinó la correlación de Spearman. El diámetro medio de fibra (DMF) se incrementó con la edad (p<0.05). El porcentaje total de fibras meduladas (TFM) aumentó de 34.79% en el grupo de 1-2 años a 74.72% a los 9-10 años (p<0.05) y el porcentaje de fibras no meduladas (FNM) disminuyó de 65.69% a 25.60% (p<0.05). Las correlaciones más resaltantes fueron entre porcentaje TFM y DMF (r=0.883) y el porcentaje FNM y DMF (r=-0.883). Se concluye que en alpacas Huacaya el diámetro de fibras meduladas es superior a las fibras sin médula, en tanto que los porcentajes de fibras meduladas son superiores a las fibras sin médula.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2023-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/2695710.15381/rivep.v34i6.26957Revista de Investigaciones Veterinarias del Perú; Vol. 34 Núm. 6 (2023); e26957Revista de Investigaciones Veterinarias del Perú; Vol. 34 No. 6 (2023); e269571682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/26957/20382Derechos de autor 2023 Ceferino U.
