Semen quality parameters (SQPs) such as motility, viability, total sperm abnormality, integrity of acrosome, plasma membrane and nucleus and vanguard distance travelled by sperm and biochemical profiles such as aspartate amino transaminase (AST), alanine amino transaminase (ALT) and lactate dehydrogenase (LDH) were studied in mithun at post thawed stage. Fifty ejaculates were collected through transrectal massage method from matured bulls and the ejaculates were divided into good and poor quality. The ejaculates were extended with Tris egg yolk citrate glycerol extender and stored in liquid nitrogen. PT seminal, biochemical profiles and zona binding per cent (BP) and binding index (BI) were studied with standard protocols. The results revealed good quality ejaculates has significantly (p<0.05) higher SQPs, BP & BI and has significantly (p<0.05) lower total sperm abnormality, AST, ALT and LDH than in the poor quality ejaculates. PT motility was positively (p<0.05) correlated with SQPs, vanguard distance, BI & BP and negatively correlated (p<0.05) with total sperm abnormality and biochemical profiles. In conclusion, the good quality sperm has higher functional sperm structures and higher intactness of sperm plasma and acrosomal membrane to motile faster in forward direction to reach the site of fertilization and successful fertilization.
