Improving Libido and Sperm Quality of Bali Bulls by Supplementation of Moringa oleifera Leaves

Moringa oleifera (Moringa) leaves contain high levels of nutrient that can be utilized as a feed supplement to increase libido and semen quality.This study was aimed to evaluate the effect of Moringa leaves supplementation on libido and sperm quality of Bali bulls.This study used two-sample t-test on four Bali bulls were kept under individual pens for two periods of eight weeks.During the first period (control), the experimental Bali bulls were fed concentrates (1% of body weight) and rice straw ad libitum.During the second period, the experimental Bali bulls were fed similar to the first period with an additional of Moringa leaves 15% of the weight of the concentrate (treatments).Libido and sperm quality were measured twice a week.Plasma samples were taken three times a day (06:00, 14:00, and 22:00h) on the last day of each period.Plasma testosterone concentrations were analyzed by using ELISA techniques.Variables measured were compared using paired student's t-test.Supplementation of Moringa leaves increased testosterone levels (P<0.05)(4.57vs 4.79, 0.45 vs 4.78, and 2.35 vs 5.63 ng/ mL, respectively during 06.00; 14.00; and 22.00h), increased libido (P<0.05)(7.20±1.49vs 3.49±0.40min), and increased both the total motility (P<0.05)(63.99±3.37%vs 84.96±3.09%)and the progressive motility (P<0.05)(52.77±1.76%vs 67.03±3.74%) of sperm.Supplementation of Moringa leaves also increased (P<0.05) the velocity and the amplitude and decreased (P<0.05) the linearity of sperm.It can be concluded that the supplementation of Moringa leaves could increase plasma testosterone concentrations, libido, and sperm motility of Bali bulls.
