This work was carried out to evaluate angular measures of foals, from birth to 12 months age, and mature animals of the Mangalarga Marchador horse. Eleven angular measures of 98 foals, 55 males and 43 females, were taken on the birth day and at each thirty days up to complete 12 months of age. Results of measures were submitted to analysis of variance and mathematical model included effects of sex, region, nutritional management, herd, month and year of birth. The variables studied were not influenced by sex, herd, nutritional management, month and year of birth. The values increases and decreases at each month, what can be result of unequal growth of bones that form the angles. Average values observed for shoulder-floor angle of foals varied from 58.3 to 63.4(0), for males, and from 58.1 to 63.1º, for females. The average value of shoulder-floor angle was 66,8º for stallions and mares. There were observed a relative agreement between the angles of anterior and posterior legs comparing values of angles shoulder-humerus with coxae-femur, humerus-radius with femur-tibia, metacarpus-phalanx with metatarsus-phalanx and tibia-metatarsus with metatarsus-phalanx. In anterior leg was observed variation directly proportional of the angles shoulder-floor and shoulder-humerus, while in posterior leg the variation there were inversely proportional between the angles coxae-floor and coxae-femur.
