Relationship between fiber diameter, weight and market price, in Junin sheep fleeces

Abstract

The objective of this study was to evaluate the relationship between the mean fiber diameter (MDF), its weight and the sale value, according to the classification categories of wool by the English-Peruvian method, such as the classification of: B, A, AA, AAA and AAAA; For this, we proceeded to obtain 25 samples of fleeces of the same number of sheep with 2 years of age, of the "Junín" breed, once the wicks were obtained, we proceeded with washing, after each wick five sub-samples were separated to measure the MDF, weight and then set the price with the help of Pro Lana as of October 13, 2021. The results indicate a high correlation between the MDF and its weight at a level of 0.01 with 0.756** and with a linear regression of 57.40%; In the same way, a high negative correlation was obtained between the MDF and its market price at a level of 0.01 with -0.985** with a linear regression of 97.10%. Concluding that the finest wool has a lower weight with a higher price and thicker wool has a higher weight with a lower price.
