Effect of Moringa oleifera on semen quality profiles in endangered Teressa goat under tropical humid island ecosystem

Objective: To investigate the effect of Moringa oleifera leaf extract on semen quality parameters in Teressa goat buck. Methods: A total of 25 semen samples from six bucks were selected for the study. Spermatozoa of 150× 106 were incubated in 0, 300, 500 and 700 μg of leaf extract as group I, II, III and IV, respectively. Liquid stored semen samples were analysed for motility, viability, total sperm abnormalities, plasma membrane, acrosomal and nuclear integrities, seminal plasma intracellular enzymes [aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH)] and total antioxidant capacity (TAC) and spermatozoa malondialdehyde (MDA) and cholesterol efflux in comparison with the control group (group I) for up to 72 h. Results: Moringa oleifera leaf extract (500 μg/150× 106 spermatozoa)-treated semen had significantly higher motility, viability, plasma membrane, acrosomal and nuclear integrities, and TAC (P
