Abstract

    The study was conducted to investigate the effects of various concentrations of bovine serum albumin (0, 2.5, 5, 10, 15 and 20 mg/ml) in extenders based on tris and egg yolk on the Mahabadi goat spermatozoa after freezing-thawing. Semen samples were collected by an artificial vagina, twice a week from four matured goat. The extender containing semen was frozen in liquid nitrogen and then was store until using for assessment. semen was thawed at 37C and then motility and progressive motility were assessed by CASA. Membrane integrity, viability, morphology and acrosome status were assessed too. The results of this experiment showed that extender containing 10 and 15 mg bovine serum albumin significantly improved motility, progressive motility and viability compare to control treatment (P0.05). It can be conclude that adding 10 and 15 mg bovine serum albumin in to goat extender is suitable for preservation of sperm and its fertility.
