Resumen
Descripción
The type traits are important for selection decisions in dairy cattle, because they have direct influence in the traits of economic interest. However, the problem associated with these traits it is the large number of traits and the high degree of collinearity and interrelationships between them. Factor analysis is a useful tool to remove redundant information between correlated variables and represents them in a small set called factor. This study aimed to evaluate the phenotypic relationship between linear type traits by means of factor analysis in Holstein cows.
