Semen samples from 12 bucks Were extended with 10 different extenders containing glycerol, DMSO, glycerol + DMSO, and glycerol + lactose in varying concentrations as cryoprotective agents. The activities of acrosin, hyaluronidase, alkaline phosphatase (AKP), aspartate aminotransferase (AST), alanine amino transferase (ALT) and lactic dehydrogenase (LDH) were assayed in equilibrated (Prefreeze) and frozen thawed (Postfreeze) semen samples. Significantly (P < 0.01) higher intracellular activity of acrosin was recorded in semen samples extended with lactose than with the other extenders, with the maximum being with Tris yolk glycerol lactose (TYGL(180)). Effects of extenders on acrosin activity were significant (P < 0.01) at both of the pre-and postfreeze stages. However, extracellular activities of hyaluronidase, alkaline phosphatase, transaminases (AST and ALT), and lactic dehydrogenase were significantly higher in extenders containing DMSO than lactose. Leakage of these enzymes was found to increase from the prefreeze to the post freeze stage.
