Summary: | This research aimed to evaluate the morphology of Brasileiro de Hipismo foals using digital image analysis and girth measurements to estimate body indexes of animals. The linear and angular measurements were obtained by digital images of the foals with camera triggered by Simi Reality Motion Systems®. The measures were based on anatomical landmarks highlighted with 19 reflective markers. A descriptive statistical analysis of the results was performed using the SAS program. The foals were growing, with increased linear measurements of height at withers and croup, body length, distance from shoulder-fetlock and neck length, leg length and forearm length. The angles humerus-radial, metacarpal-falangeano, femoro-tibial, tibio-metatarsal increased with age, whiles the angles of the head, neck, coxofemoral, metatarsal-falangeano, shoulder-floor and coxae-floor were variable among the periods. The foals were classified as medium shape and hypermetric by Corporal Index, Dactilo-thoracic Index, respectively. Assessment of growth of the foals was possible through a digital image. Key words: conformation, equines, equestrian sports, digital image, morphology. Objetivou-se avaliar a morfologia de potros da raca Brasileiro de Hipismo, utilizando analise de imagens digitais e medidas de perimetros corporais para estimativa de indices corporais dos animais. As mensuracoes lineares e angulares foram obtidas utilizando imagens digitais dos potros com camera acionada pelo aplicativo Simi Reality Motion Systems®. As medidas foram baseadas em pontos anatomicos realcados com 19 marcadores reflexivos. A analise estatistica descritiva dos resultados foi realizada utilizando o programa SAS. Os potros estavam em crescimento, com aumento das medidas lineares de altura na cernelha e na garupa, comprimento do corpo, distancia escapulo-metacarpofalangica e nos comprimentos do pescoco, da perna e do antebraco. Os angulos umero-radial, metacarpofalangico, femoro-tibial, tibio-metatarsico aumentaram com a idade, enquanto que os angulos da cabeca, do pescoco, coxofemoral, metatarso-falangico, escapulo-solo e coxo-solo foram variaveis entre os momentos de avaliacao. Os potros foram classificados em mediolineos e hipermetricos pelos indices Corporal e Dactilo-toracico, respectivamente. A avaliacao do crescimento dos potros foi possivel atraves da imagem digital. Palavras-chave: cavalos, conformacao, hipismo, imagem digital, morfologia. |
