A total of 24 ejaculates were obtained from six cross-bred bulls using an electro-ejaculator. The extract of Eurycoma longifolia jack was distributed into three low doses and three high doses; cryopreserved samples were evaluated into three different times to confirm the results of kinetic motilities through different times and between groups. Path velocity (VAP μm/s), progress velocity (VSL μm/s), track speed (VCL μm/s), lateral amplitude (ALH μm/s), Beat Frequency (BCF Hz), straightness (STR %), linearity (LIN %), were evaluated three different times using Computer-assisted sperm analysis. Results revealed that the percentage of VAP, ASL and VCL were higher (p}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
