  Objectives: As very few studies were done on the freezability of pure Egyptian cattle bull sperm. So, we designed this study to evaluate the individual variations in freezability of native bull semen extended in Tris based diluent and sodium citrate-based diluent. Methods: Semen was collected by artificial vagina, examined at once in farm laboratory. Only semen samples fit the minimum parameters are extended in two extenders first the universal one (TRIS) and second modified Sodium citrate extender by adding glycerol (CU-16) which created at Cornell University to evaluate the individual bull variation and interaction between extender and bull. Results: Post-Thawing individual sperm motility, live, abnormal, acrosome integrity percentage was evaluated in addition to Hypo-Osmotic Swelling test (HOS). The highest value for .. View More»
