The basic is the “linear description” of the different body areas of an animal through numbers that have a range between two extremes representing the biological extremes of the trait. This method allows the statistic elaboration of the Genetic Indices.

The aim is to use the morphological evaluation and check the conformity to the Breed Standards in order to accept or not the animal in the Herd Book and to know the genetic value of its morphological traits (size, leg-set, muscularity and fineness).
