| Abstract: | The aim of this study was to determine the effects of raffinose and hypotaurine on sperm parameters after the freeze–thawing of Merino ram sperm. Totally 40 ejaculates of five Merino ram were used in the study. Semen samples, which were diluted with a Tris-based extender containing 10 mM raffinose, 5 mM hypotaurine, 5 mM raffinose +2.5 mM hypotaurine (H + R) and no antioxidant (control), were cooled to 5 °C and frozen in 0.25 ml French straws and stored in liquid nitrogen. Frozen straws were then thawed individually at 37 °C for 25 s in a water bath for evaluation. |
