The present study was carried out at the IVITA-Maranganí Experimental Station to evaluate the effect of two levels of feeding on the yield and quality of alpaca fibre.Twelve young male alpacas were used. A pre experimerntal phase was conducted for the adaptation of the animals to the balanced diet and an experimental phase with four periods was considered: Periods I and III of 28 days each were used to level body condition; in period II the animals were submitted to treatment T1 and T2, receiving 0.73 and 1.23 times the maintenance requirement for 84 days; and in period IV the animals of T1 were shifted to T2 and vice versa for another 84 days. In periods II and IV, fiber samples were taken from a 100 cm2 area on the right mid rib area, and was measured the yield, diameter (D), length (L), volume (V), L/D ratio and the contribution of L, D and (D)(L) on fibre volume. T2 was statistically superior to T1 (p<0.05) in fibre yield (5.22 vs. 4.43 g/100 cm2), D (25.75 vs. 23.97 μ), L (319.6 y 294.7 μ/d) and V (162.8 vs. 132.95 x 10-3 μ/d respectively) while the L/ D ratio was similar in both treatments. D, L and (D)(L) contributed with 68.6, 27.2 and 4.2% to fibre volume, respectively. It is concluded that the feeding levels in the alpaca influenced both the yield and volume of fibre, and that the contribution of D in the fibre volume resulted higher than the L contribution. |

Se utilizó 12 alpacas Huacaya machos jóvenes. Se tuvo una fase pre-experimental para el acostumbramiento de los animales a una dieta balanceada y una fase experimental con cuatro periodos: los periodos I y III, de 28 días cada uno, se usaron para igualar condiciones corporales; en el periodo II los animales fueron sometidos a los tratamientos T1 y T2 ofreciéndoles 0.73 y 1.23 veces el requerimiento energético de mantenimiento por 84 días; y en el periodo IV los animales del T1 pasaron al T2 y viceversa por otros 84 días. En los periodos II y IV se tomaron muestras de fibra de un área de 100 cm2 sobre el costillar medio derecho, midiéndose el rendimiento, el diámetro (D), la longitud (L), la relación de L/ D, el volumen (V), y el aporte de L, D y (D)(L) en el V de la fibra. El T2 fue significativamente superior al T1 (p<0.05) en rendimiento de la fibra (5.22 vs. 4.43 g/100 cm2), D (25.75 vs. 23.97 μ), L (319.6 y 294.7 μ/d) y V (162.8 vs. 132.95 x 10-3 μ/d, respectivamente), en tanto que la relación L/D fue similar en ambos tratamientos. D, L y (D)(L) aportaron el 68.6, 27.2 y 4.2% al V de la fibra, respectivamente. Se concluye que los niveles alimenticios en la alpaca influyen tanto en la producción como en el volumen de la fibra y que el aporte del D en el incremento de la fibra resultante es mayor que el aporte de L.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2009-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/60510.15381/rivep.v20i2.605Revista de Investigaciones Veterinarias del Perú; Vol. 20 Núm. 2 (2009); 187-195Revista de Investigaciones Veterinarias del Perú; Vol. 20 No. 2 (2009); 187-1951682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/605/479Derechos de autor 2009 Francisco Franco F., Felipe San Martín H., Miguel Ara G., Juan Olazabal L., Fernando Carcelén C.https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/6052020-03-16T17:55:49Z |
