"Curtición de Pieles de Cuy para Peletería con Utilización de Diferentes Niveles de Alumbre"

Abstract

At the Sking Tanning lab of the cattle and livestock Science Faculty of the Escuela superior Politécnica del Chimborazo, the cavy skin tanning was caried out for furriery with with the use of different alum levels (7, 8 and 9%) ,. The treatments corresponding to the alum levels (factor A), modeled under a completely at random design with a bifactorial arrangement in two consecutive trials (factor B), and 16 replications giving a total of 96 experimental units were used. In the analysis of physical resistance of lastometry (8.77 mm), and traction resistance (91.31 N / cm), the best results were recorded upon tanning the cavy skin with 9% alum (T3), white the highest elongation percentage (65%) , was obtained working with 7% alum (T1) ,: The highest sense marks were reported opn tanning uodn pa cavy skins with 9% alum (T3), As to the hair fineness (4.63 points), color intensity (4.19 points), and softness (3.94 points), scores of excellent and very good were recorded. For the benefit-cost analysis it was evident that upon using 9% alum (T3), profit was higher with 1.18 USD i.e. for each invested dollar an 18 cent gain is expected. It is therefore recommended to tan the cavy skins with 9% de alum sulfate as with it better sense marks and a higher profit are obtained.
