The pelvimetry is the metric determination of the pelvic dimensions and its use is directly connected with reproduction. In pacas, the pelvis is tight, elongated and in 5 diameters, radiographically analyzed, in up to 12-month old animals, 3 of them (longitudinal, coxal, and acetabular) presented crescent and different values in almost all of the time. The aim of this research is to perform, through radiography, pelvimetry in animals between 12th and 24th month-old animals, as for as the longitudinal, coxal and acetabular diameters, which did not reach stable values through the first year of live-in pacas, the second-largest Brazilian rodent, and an animal that has gained recent great scientific interest in many studies. Then, 8 animals will be evaluated with radiographs every month from 12th and 24th months of life, or until those diameters reach stable values for, at least, 4 months in a roll.
