ABSTRACT
Morphometric assessment of horses is an important instrument selection, because it is
related to the functionality of this species. In the first chapter we evaluated the evolution of
morphometric measurements of Mangalarga Marchador (MM). We used linear measures
stored in the database of the Genealogical Registry Service, in a completely randomized
design, with treatments consisting of the years between 1970 and 2010. The selection of
race MM gave the animals shorter head, greater stature, shorter torso length and larger
diameter of the bony rays. In the second chapter we compared measures of the current herd
MM with exemplary champions, and were determined morphometric measures of the true
type of race. The design was completely random, and the treatments for the herd MM
registered between 2000 and 2010, and the animals champions measured for three national
expositions. The differences between the measurements of mares champions, relative the
herd of females, are larger which among horses champions and herd male. Although
champions horses MM present greatest linear measurements, they are proportionally
similar to the population of the breed. In the third chapter we compared morphometric
measures of MM horses of categories batida and picada marcha. We compared
morphometric measurements of horses in both categories, in a completely randomized
design. In MM horses of categories batida and picada marcha most of the measures have
similar values, however, there are differences between some angles of members.
