				Abstract 
 
              
              
              Aim: 
              
              Viable spermatozoa could be recovered from the cauda epididymides 
              for the purpose of preservation of genetic material of male 
              animals with desirable traits and for use in reproductive 
              biotechnology. The aim of this study was to determine the effect 
              of storage time on testicular and epididymal biometry, sperm 
              reserves and epididymal sperm characteristics of red Sokoto bucks 
              post mortem. 
              
              
              Materials and Methods: 
              
              Testes-epididymides were collected immediately after slaughter of 
              mature red Sokoto bucks and trans-ported in ice chest to the 
              laboratory. The samples were either processed immediately or 
              stored at 5°C in refrigerator for 24, 48 h and then processed. The 
              testes and epididymides were measured and weighed. Sperm motility, 
              concentration, livability, morphology, intact acrosome from different treatment groups including control were 
              evaluated and means (±standard error of mean) were recorded. 
              
              
              Results: 
              
              There was no significant difference (p>0.05) in the testicular and 
              epididymal dimensions determined between the means of the groups. 
              Percent sperm motility and viability decreased significantly 
              (p<0.05) after 24 h from 69.00±0.46 and 71.27±0.50% to 50.60±0.48 
              and 60.47±0.70% at 48 h, respectively. Significant decreases 
              (p<0.05) in epididymal sperm concentration and intact acrosome 
              from 2.86±0.08 and 92.87±0.39 at 0 to 24 h of storage, 
              respectively, were observed. 
              
              
              Conclusion: 
              
              The results of this study suggest that spermatozoa recovered from 
              the epididymides of red Sokoto bucks were viable after storage for 
              up to 48 h. Furthermore, this finding offers some hope that 
              epididymal sperm recovered post-mortem can be used in assisted 
              reproductive technologies.
