This study aimed to determine the participation frequency and competitive performance of Campolina and Mangalarga Marchador horses in national shows concerning marcha type, sex, and age. To that end, the trial results of national horse shows between 2007 and 2017, comprising 1,781 Campolina and 5,239 Mangalarga Marchador animals, were extracted from the databases of the breeders' associations of each breed. The results regarding participation frequency in these events and the performance achieved by horses were grouped by breed, marcha type, sex, and age group and then subjected to frequency distribution tests. In both breeds, most animals attended only one national show. However, when the specimens were separated by marcha type, sex, and age, it was observed that 54.39% of marcha batida Campolina males competed twice, with greater participation of adult horses (41.41%) than of young ones (22.22%). For Mangalarga Marchador, irrespective of gait type, the proportion of adult horses (67.22%) that competed was higher than that of young ones (25.63%). For marcha picada competitors, the proportion between young (13.97%) and adult (81.91%) was even higher. It was concluded that, over their competitive careers, most horses of either breed attended only one national show, that marcha picada animals usually compete only when adults, and that marcha batida females compete more often when young. In addition, the age group in which competitors achieve their best performances varies according to the specimen.
Objetivou-se com o trabalho caracterizar os equinos participantes de Pegas de Boi no Mato e verificar se esses animais permanecem com as características físicas do remanescente cavalo Nordestino, raça pioneira na lida com o gado no Sertão, ou se estão aproximando das dimensões corporais dos cavalos Quarto de Milha, raça exótica em ascensão no Nordeste brasileiro devido às Vaquejadas. Para tanto, foram utilizados 102 equinos participantes de Pegas de Boi no Mato. A primeira etapa do estudo consistiu em uma entrevista aos proprietários dos cavalos, com aplicação de questionário predefinido, para obter informações sobre os animais. Na segunda etapa foram obtidas 15 medidas lineares dos equinos e com elas calculados sete índices morfométricos. As medidas foram utilizadas para comparar dois grupos raciais, mestiços e animais sem raça definida, através do delineamento experimental inteiramente ao acaso composto pelos dois tratamentos (grupos raciais). Observou-se nas Pegas de Boi no Mato, predomínio de equinos machos castrados, na faixa etária entre 5 e 10 anos, de pelagens alazã, tordilha e castanha, cujas funções vão além das participações nas disputas. Os equinos mestiços apresentaram valores superiores aos animais sem raça definida em nove das 15 medidas lineares. Além disso, houve diferença entre os grupos raciais em cinco dos sete índices morfométricos. Concluiu-se que tanto os mestiços quanto os equinos sem raça definida participantes das Pegas de Boi no Mato possuem medidas e proporções corporais intermediárias entre o remanescente cavalo Nordestino e equinos Quarto de Milha de Vaquejada.
