Résumé : | This study was conducted to evaluate the effects of different temperatures and doses on stallion sperm survival after 24 h and 48 h short-term storage. Ejaculates from four warm-blooded stallions were used in this study. Ejaculates were collected by an open-ended artificial vagina which separates fractions of semen into sterile plastic cups. Only the second and third fractions (spermatozoa-rich fractions) were used to obtain spermatozoa for the experiment. Semen was diluted with INRA 96 extender to final concentrations of 50, 100, 200 and 400x106sp/ml. Diluted semen were stored at different temperatures (2, 4 or 8C) for 24-48 h. After 24 h and 48 h cooled storage, spermatozoon motility, abnormal spermatozoon ratio and membrane integrity were evaluated. According to results the highest motility values (52.5% and 55%) were determined at 50 and 100 x106sp/ml concentration at 4C after 24 h cooled storage. After 48 h of storage, the highest motility was obtained from semen stored at 8C. Abnormal spermatozoon and membrane integrity values were not significantly different after cooled storage. Consequently, it was determined that semen with 50 and 100 million spermatozoa/ml concentration stored at 4C for 24 h and semen with 50, 100, 200, 400 million spermatozoa/ml concentration stored at 8C for 48 h gave better results with respect to motility than the others. |
