Caracterización de la calidad de lana de ovinos 4m en el cantón Guamote, provincia de Chimborazo.

Abstract

The objective of this research was to characterize the wool quality of 4M sheep in Guamote Canton to determine the influence of sex and age. A completely randomized design with a combinatorial arrangement of two factors was applied: Factor A age (young and adults) and Factor B sex (males and females), and the interaction between the two factors, the separation of means through Tukey's test, To determine the degree of relationship between the variables, Pearson's correlation coefficient was used to evaluate the effect of sex and age on wool quality 60 sheep of different sexes, males and females, aged between 2 and 4 years, were selected from which wool samples were taken from the midrib and evaluated from ten fibers selected at random from each sample where the physical properties were determined such as the number of curls per inch, length of wick, diameter, and physical properties such as the number of curls per inch, To determine the rate of medulation, a lanometer was used to observe the presence or absence of pith through a lens with a 10x objective. There was influence of sex and age presenting significant differences, a greater diameter in animals of 4 years old with 24.76 μ, those of 2 years old 21.2μ, length of the wick of 9.23 cm for males and 7.84 cm for females, the samples did not present presence of medulation, the high superior correlations (r>0. 8) that determines an absolute correlation between two variables, it was concluded that 4M sheep presented fineness characteristics of 21.2μ and 24.76μ, it is recommended that the research serve as a basis for wool producers in the country.
