The objective of this study was to assess the influence of spermatozoa surface antigenic proteins on the functional competence of bovine neat and frozen-thawed semen. The breeding bulls (n = 38) were screened for seminal antigenic levels in neat semen based on the agglutination titrations with anti-sperm antibody (ASA). Bulls having high (n = 8) and low (n = 7) antigenic levels were selected and spermatozoa functional parameters were analyzed in neat and frozen-thawed semen samples. In neat semen, kinematics such as straightness (73.6 ± 1.0 and 66.9 ± 1.5%), linearity (48.6 ± 1.2 and 40.1 ± 3.9%), curvilinear velocity (103.3 ± 2.6 and 93.4 ± 3.8 μm/s), straight-line velocity (65.7 ± 2.6 and 53.7 ± 2.2 μm/s) and average path velocity (53.8 ± 2.5 and 39.8 ± 2.3 μm/s) were significantly high (p < 0.05) in samples with lower antigenicity. The percentage of spermatozoa that can penetrate mucus (49.9 ± 2.3 and 37 …
