| Abstract | This study aimed to compare the post-thaw quality of frozen semen from American Brahman and Charolais bulls using Computer-Assisted Sperm Analysis (CASA). Frozen semen from 8 American Brahman and 8 Charolais bulls, with 10 straws per bull, was thawed at 37 °C for 30 seconds and evaluated for total motility, progressive motility, sperm morphology, and kinematic parameters, including linearity, beat-cross frequency, amplitude of lateral head displacement, and the ratio of straight-line velocity to curvilinear velocity. The results showed that sperm from American Brahman bulls had significantly higher progressive motility and linearity compared to Charolais bulls (P<0.05), whereas Charolais bulls exhibited significantly higher beat-cross frequency than American Brahman bulls (P<0.05). No significant differences were observed in total motility or other evaluated parameters (P>0.05). These findings indicate some breed-specific differences in post-thaw semen quality, which can be used to support the selection of suitable sires for artificial insemination and genetic improvement of beef cattle under tropical conditions in Thailand. |
