Dopplerfluxometria na avaliação andrológica de bovinos no período peripuberal / Dopplerfluxometry on breeding soundness evaluation of peripubertal bulls

ABSTRACT

The aim of this study was to evaluate the testicular Doppler and sperm traits in young bulls at differentage groups (24 months of age). Doppler ultrasonography was performed to study testicular bloodflow. It was conducted breeding soundness evaluation and physical and morphological characteristics of semenwere evaluated. The 24 months old animals. In pubertal animals, the percentage of normal spermcells did not differ significantly. The Doppler evaluation of testicular plexus and parenchyma blood vesselsshowed no significant differences in velocimetry nor flowmetry. It was concluded that there is no significantrelationship between scrotal circumference, sperm characteristics and testicular Doppler data in normal bullsduring the peripubertal period.
