Abstract

Background: Unique omega-3 fatty acids may contribute to the membrane fluidity which is necessary for the motility of sperm tails and also dietary fish oil (FO) can improve sperm quality. The positive effects of L-carnitine (LCAR) on male reproductive performance have been reported in some species. This study has been focused on the plasma membrane integrity and mitochondrial membrane potential in Iranian ram fed FO and/or LCAR, that till now, there is no report this issue.Materials and Methods: Nineteen Zandi rams were randomly assigned to experimental groups and were offered an isoenergetic and isonitrogenous ration. The treatments consisted of control (CTR; n=4); fish oil (FO); 35 g/d/ram; n=4); L-carnitine (LCAR; 220 ppm/d/ram; n=4) and FO+LCAR (n=4) with constant level of Vitamin E. In addition, three rams were used without Vitamin E.Diets were fed to the rams for 70 days and semen was collected once a week. Sperm routine parameters were analyzed by CASA. Sperm plasma membrane integrity and mitochondrial membrane potential (MMP) assessed by hypo-osmotic swelling test (HOST) and JC-1 respectively.Data were analyzed by SPSS 16.Results: The results showed that all sperm characteristics increased with FO. HOST-positive spermatozoa were significantly different between control and FO+LCAR (87 vs.82 vs.77 and 76% for FO+LCAR, FO, LCAR and CTR, respectively; p<0.05). MMP was affected and increased by inclusion FO+LCAR in diet (85.5 vs.76 and 75 vs.64%, FO+LCAR, FO, LCAR and CTR, respectively; p<0.05).Conclusion: Addition of FO in combination with LCAR could improve sperm functional test significantly.On the other hand, lonely LCAR at this supplemental level did not improve plasma membrane integrity in comparison with CTR, but it is effective on mitochondrial membrane potential. FO and LCAR treatments have similar effects on mitochondrial membrane potential.
