It has been found that Mn2+ supplementation improves (P¡Ü0.05) the motility at 0, 2, 4 and 6 h of incubation. MDA (malondialdehyde), end product of lipid peroxidation, decreases significantly (P¡Ü0.05) with the supplementation of manganese at 0- and 6-hr of incubation both in fresh and chilled semen. Manganese also increases acrosome reaction significantly (P¡Ü0.05) both in fresh and chilled semen at 0, 4 and 6 h of incubation. Therefore, our findings suggest the role of Mn2+supplementation in improving the quality of cattle bull semen by its scavenging property i.e. reduction in the production of reactive oxygen species during its storage at 4¡ãC or incubation at 37¡ãC for capacitation. %K Acrosome reaction %K bull %K capacitation %K manganese %K spermatozoa %U http://www.pagepress.org/journals/index.php/vsd/article/view/3479
