<br/><br/> Soybean lecithin has been attracted increasing attention and has been used to replace egg yolk in the semen extender. In the present study, effect of soybean lecithin on bovine semen freezability and in vitro fertilizing potentials were evaluated. Semen was cryopreserved in tris-based extender supplemented with different soybean lecithin concentrations (3, 5, 7, 10 and 20%) vs 20% egg yolk (control). Semen post-thawing motility, viability and acrosomal integrity, DNA damage, enzymes leakage, total antioxidant activity (TAC), lipid peroxidation and in vitro fertilizing potentials were assessed.
