Zusammenfassung:The breeding soundness exam is an important tool in selecting improvers herd bulls, since it allows the identification of problems of infertility and subfertility in males, maximizing the use of these animals in the breeding season and considerably improving the squad pregnancy rates. The purpose of this study was to describe the spermatic profile bulls Sindi, a farm in the town of Johnstown Bridge in the north of Minas Gerais. We evaluated 11 separate two bulls G1 36 months (n = 5) raised on pasture. The animals were initially weighed and identified, measured scrotal circumference, where scores a 33.8 cm to 38.2 cm and G1 to G2 and subsequently collecting the semen was performed using the eletroejaculator. The ejaculate was subjected to microscopic analysis for evaluating motility swirling and place yielding 78.4 motility values and 65%, force and turbulence 3.5 and 2.6 2.4 for 3 and G1 and G2 respectively . A sample of this ejaculate was subjected to examination of morphology, using the rose bengal dye preparation and wet smear technique using hematoxylin eosin dye. The results obtained for the G1 was 1.85% of minor flaws and defects greater than 7.75% in the art with the Rose Bengal dye and 1.15% and 12.25% of larger and smaller defects respectively with hematoxylin eosin. G2 had values of 2.4 and 9.8% for major faults and minor staining with rose bengal and 0.7 and 9.4% for both major and minor defects using hematoxylin eosin. O exame andrológico é uma importante ferramenta na seleção de touros melhoradores do rebanho, pois possibilita a identificação de problemas de infertilidade e subfertilidade dos machos, maximizando o uso destes animais na estação de monta e melhorando consideravelmente os índices de prenhez do plantel. O propósito deste trabalho foi descrever o perfil espermático de touros da raça Sindi, de uma fazenda na cidade de São João da Ponte, no norte de Minas Gerais. Foram avaliados 11 touros separados em dois grupos G1 < 36 meses (n=6) e G2 > 36 meses (n=5) criados a pasto. Os animais foram inicialmente pesados e identificados, mensurada a circunferência escrotal, onde se obteve uma média de 33,8 cm para o G1 e de 38,2 cm para o G2 e, posteriormente, foi realizada a coleta do sêmen com o uso do eletroejaculador. O ejaculado foi submetido à análise microscópica para avaliação de turbilhonamento motilidade, e vigor obtendo-se os valores de motilidade de 78,4 e 65%, vigor 3,5 e 2,6 e turbilhonamento 3 e 2,4 para G1 e G2 respectivamente.
