The aim of this research was to evaluate the phaneroptic and morphometric traits of the peruvian creole cattle in Ayacucho, Puno and Cajamarca; including coat traits, biometric measures and indexes. The data was collected from 421 cattles (194 males and 227 females) with four or more permanent teeth. The phaneroptic traits (color pattern, coat denomination and primary color) were evaluated by observation and photographic record. The biometric traits were evaluated in two regions (Ayacucho y Puno). The phaneroptic traits were analyzed by frequency tabulations and comparison of proportions. The analysis of the biometric measures included the estimation of central tendency and dispersion, a completely ramdomized design was used to compare the differences between regions, a factorial arrangement (2x3) was used to evaluate the effect of the sex and the age, and pearson correlation was used to evaluate the associations amount the traits. The results indicate higher incidence of black coat and simple pattern (92,5 and 83,6; 62,8 and 42; 47,1 and 38,8 percentage in Puno, Cajamarca, Ayacucho, respectively). The creoles in Puno had more body development than the creoles in Ayacucho (124,89 ± 0,59 cm vs. 113,53 ± 1,15 cm of height at withers; 169,55 ± 1,44 cm vs. 157,09 ± 1,03 cm of toracic perimeter; 146,20 ± 2,46 cm vs. 127,56 ± 1,51 cm of body length, respectively). The biometric indexes of creole of Ayacucho do not correspond to a dairy or beef orientation (dactylo-thoracic index of 10,42 ± 0,08 and body side index of 89,13 ± 1,02); while the fineness of the skeleton of the creole of Puno show a milk orientation (dactyle-thoracic index of 9,89 ± 0,08). The creole bovines show differences in their phaneroptic and morphometric traits according to the region; which they should be considered in breeding programs.
