One of the main factors known to influence quality and fertility of bovine cryopreserved semen is the extender used. In this matter, a great worldwide interest has been directed to the development of chemically defined media, free of animal origin products. The objective of the present study was to compare the efficacy of three bovine semen extenders: Tris–fructose (TRIS, control with 20% egg yolk), Botu-Bov (BB; 20% egg yolk), and Botu-Bov-soy lecithin (BB-L; 1% soy lecithin).
