Using Gum Arabic in Place of Egg Yolk as Cryoprotectant for Cryopreservation of the Buck Semen

Background: Egg yolk (EY) is well known to be toxic for buck spermatozoa, which creates restrictions of its use in cryopreservation. Therefore, this study compare the effect different levels gum Arabic (GA) an extender on quality and fertility cryopreserved sperm. Methods: Each ejaculate six bucks was frozen Tris with one concentrations GA contained 3, 6, 9 12 gm/ 100 ml place EY. Control containing 2.5% Result: A percentages total motile sperm (54.92%; P less than 0.05) progressively (26.22%; semen 9% GA. Similar control group, pregnancy rate does inseminated (50.0%) were significantly higher those 6% (8.33%), 3% (0.0%) 12% (0.0%). Semen evaluation similar when replacing EY cryodiluent, after cryopreservation semen. The present shows that high motility acceptable can obtained using cryopreserving
