Comparison of Whole and Centrifuged Egg-Yolk Added to Kenney ’s and Lactose-EDTA Extenders for Donkey Semen Cryopreservation

Artificial insemination (AI) is the reproductive technique that most influences animal production and using frozen semen presents numerous advantages such as conservation, commercialization and ease of distribution of desirable genes, while allowing sanitary control of semen samples. Although whole egg-yolk (EY) has been the component most widely used as the external cryoprotectant for donkey semen extenders with any degree of success, among its disadvantages is that the large granular material and debris it provides may interfere with sperm metabolism and with semen evaluation as it is of the same size and shape as sperm.
