Caracterización de la fibra de Vicugna pacos (Alpaca) de la parroquia san Juan, provincia de Chimborazo

Abstract

The quality fiber of 143 alpacas, before hearing, and, belonging to three communities (Chorrera Mirador, Pulingui San Pablo, Tambohuasha) of San Juan (Chimborazo province, Ecuador ) was evaluated from ten fibers randomly selected from each sample, the absolute length (LA), relative length (LR) number of crimps (NR), diameter (D) and medullation rate (M) were determined. The effect of sex, location and age was assessed by applying multifactorial ANOVA. Subsequently, correlations between parameters were determined by using the Pearson correlation coefficients. The effect of the location for LA, LR, NR, and M parameters; was observed. The sex an age affected the LA, LR, NR, D; significantly. For the variable M; it was not detected any difference caused by sex and age. Regarding to the correlations between the parameters evaluated; between the LA and LR, and, between LA and difference in lengths; a high and significant correlation was found out, in addition to his, an average and significant correlation between D and M was found. Talking into account the information previously mentioned, it can be concluded that the community of origin of the animals, affected significantly the quality of the fiber only in females. The sex and age showed effects on the diameter, total length, relative length and number of crimps; the effect of gender and age in the medullation of the fiber of the animals studied. It is recommended that this research contributes as database for producers in the country.
