ABSTRACT
This study was designed to assess the cryosurvival of beetal buck spermatozoa with the supplementation of Glutathione (GLU) and L-cysteine (CYS) in the extender. In the first experiment, semen samples from each of the five mature bucks were pooled and diluted in Tris-citric acid (TCA) extender containing Glutathione (0.5mM, 1mM), L-cysteine (5mM CYS, 10mM CYS), and control. In experiment 2, semen samples (n=5) were diluted in TCA extender containing differential doses of combined antioxidants (0.5 mM GLU+ 5mM CYS, 0.5mM + 10mM CYS, 1mM GLU + 5mM CYS, 1mM GLU + 10mM CYS and Control). At post-thawing, progressive motility, plasma membrane integrity (PMI), and livability of buck spermatozoa were higher (P< 0.05) with 1mM GLU and 10mM CYS as compared to control. In the second experiment, post-thaw progressive motility, PMI, and livability were higher (P< 0.05) with 1mM GLU + 10mM CYS and 1mM GLU + 5mM CYS compared to other doses of GLU+CYS and control. We concluded that optimized supplementation of Glutathione and L-cysteine in TCA extender ameliorated frozen-thawed quality of beetal buck spermatozoa.
