Moringa oleifera leaves extract enhances fresh and cryopreserved semen characters of Barki rams

• This study was carried out to evaluate the efficacy of Moringa oleifera leaves extract (MOLE) to improve the characters of fresh and cryopreserved semen of Barki rams compared to vitamin E and Selenium combination. Twenty-four mature Barki rams (50-70 Kg) were randomly assigned into three groups, eight rams each. The first group was given distilled water orally. The second group was given MOLE orally daily at a dose of 40 mg/kg. The third group was injected with a combination of vitamin E and selenium at a dose of 3 ml (4.5 mg sodium selenite and 204 mg vitamin E)/head i.m twice a week for 64 days. Moringa oleifera leaves extract increased semen volume, sperm concentration, activities of seminal plasma catalase, glutathione peroxidase (GPx), glutathione reductase (GR), superoxide dismutase (SOD), alkaline phosphatase (ALP), acid phosphatase (ACP), levels of ascorbic acid and total antioxidant capacity (TAC). In addition, it significantly increased post thawing sperms motility, viability index, membrane integrity, and the activities of post thawing semen antioxidant enzymes. While it decreased seminal plasma concentration of malondialdehyde (MDA) and acrosomal defects and DNA fragmentation of sperm in cryopreserved semen. Vitamin E and selenium decreased semin volume, sperm concentration, seminal plasma ascorbic acid, TAC concentrations and activities of antioxidant enzymes while it increased sperm abnormalities, DNA fragmentation and MDA concentration in seminal plasma. This study indicated that Moringa oleifera leaves extract improved the characters of the fresh and cryopreserved semen of Barki rams via improving seminal plasma antioxidant defense mechanism.
