Coenzyme Q10 (CoQ10) serves as an antioxidant, and it is considered an energy source. Ubiquinol inhibits lipid peroxidation and protein oxidation. We fed CoQ10-ubiquinol in donkeys' feed and investigated its effect on plasma hormone concentrations of Testosterone (T), Activin-A, Luteinizing Hormone (LH), follicle-stimulating hormone (FSH), Antimullerian hormone (AMH), estradiol (E2), and Q10 in donkeys. For this purpose, Dezhou jacks, n=30, were equally divided into groups A, B, and C. Group A donkeys were given 2 g Uboquinol (CoQ10)/day. Group B received 1.5 g CoQ10/day, and group C served as the control group. Experimental duration was 56 days. The objective of the present study was to check the effect of various concentrations of Coenzyme Q10 (Ubiquinol) on plasma hormones that ultimately affect semen quality in donkeys, especially during the non-breeding season. Results indicate that the addition of Ubiquinol in donkey feed has a tendency to improve plasma hormone concentrations of T, FSH, LH, AMH, Activin-A, E2, and Q10. Our findings suggested that feeding 2 g of Ubiquinol/day mixed into 1 pound of grain-based concentrate with molasses improved plasma hormone concentrations. In conclusion, our findings suggest that feeding CoQ10 may improve donkey semen quality.
