<br/><br/> Semen extenders containing egg yolk as a cryoprotectant may pose hygienic risks and are difficult to standardize. Although a new generation of semen extenders free of animal ingredients is available. egg yolk-containing extenders are still widely used for cryopreserving semen. The aim of the present study was to compare the effect of using soy lecithin-based extenders, Biociphos and Bioxcell, and egg yolk-based extender on buffalo spermatozoa freczability and fertilizing potentials. Extension of buffalo bull semen in the Bioxcell and the Biociphos extenders significantly increased (P<O.OI) the post-thaw spenn motility (61.67 and 60.00%, respectively) and the viability index (130.83 and 120.00, respectively) compared to semen that extended in the IRIS-egg yolk extender (38.33% and 88.33, respectively).
