Özet
This study was conducted to determine the effects of cysteamine, hypotaurine and aminoacids solution (BME) on standard semen parameters, lipid peroxidation and antioxidant activities of Angora goat semen after the freeze-thawing process. Ejaculates collected from four Angora goats were evaluated and pooled at 37 degrees C. Semen samples, which were diluted with a Tris-based extender containing the antioxidants hypotaurine (5 mM) and cysteamine (5 mM), and an aminoacid solution (13%), and an extender containing no antioxidants (control), were cooled to 5 degrees C and frozen in 0.25-ml French straws in liquid nitrogen. Frozen straws were thawed individually at 37 degrees C for 20 s in a water bath for evaluation. Supplementation with cysteamine, hypotaurine and BME caused significant (P < 0.05) increases in sperm motility, and significant (P < 0.05) decreases in total abnormality rates in comparison to the control group. While all in vitro treatments did not affect the acrosomal abnormality rates, hypotaurine and BME but not cysteamine significantly (P < 0.05) increased the HOST results as compared to the control group. Supplementation with antioxidants and BME did not significantly affect MDA levels and CAT activity in comparison to the control group (P > 0.05). The antioxidants hypotaurine and cysteamine decreased SOD activity when compared to the BME group and controls (P < 0.001). (c) 2009 Elsevier Ltd. All rights reserved.
