Online published on 23 January, 2012. Abstract Cryopreservation of semen is a capacitating as well as damaging process in which there is reduction in the post thaw semen quality. Free radical mediated damage is the key phenomenon which not only causes the loss of post thaw quality of semen but also impedes the molecular architecture of the sperm which instead questions the outcome of artificial insemination. With this over view, the present study was designed to evaluate the effect of oral supplementation of zinc and selenium on the post thaw quality of Barbari buck semen. The study was performed in 8 bucks of aged between 2–4 years which were orally supplemented with Zinc Sulfate (@ 150 ppm) and Sodium Selenate (@ 0.50 ppm) for 105 days. The post thaw quality of the semen was accessed by evaluation of progressive sperm motility, sperm liveability and normal and abnormal sperm count. The results obtained were compared with that of the non supplemented control group. The sperm quality was analysed on 0, 60, 75, 90 and 105 days following Zn and Se supplementation. The results exhibited a significant difference (P<=0.05) between the control and the experimental groups for post thaw progressive sperm motility, sperm liveability and abnormal sperm count. But the results between the treatment groups showed variable results. However, the significant difference was not observed between the different periods of the control groups. It can be concluded from the present study that oral supplementation of Zn and Se may have some protective effect on sperms which brought about the improvement in the post thaw quality of the sperms.
