Abstract: The aim of the present study was to assess and compare semen parameters in Mehsana buffalo bulls classified as high-fertile and low-fertile based on their conception rates (CR). Twelve bulls were selected and divided into two groups (high-fertile with CR > 43% and low-fertile with CR < 35%). Frozen semen samples (n=72) were randomly chosen for analysis. Results showed that high-fertile bulls exhibited significantly (p<0.05) higher live sperm counts compared to low-fertile ones. Additionally, low-fertile bulls had significantly (p<0.05) higher rates of head abnormalities and total abnormalities. However, differences in mid-piece abnormalities, percent abnormal tail and tail less head were not statistically significant between the two groups. There were no significant variations in percent HOS reactive sperm and lipid peroxidation (MDA) between high-fertile and low-fertile groups. The study suggests a correlation between head morphology, sperm viability and fertility in Mehsana buffalo bulls.
