Abstract

The aim of this study was to search for the effects of antioxidants taurine, GSH and trehalose on liquid storage of ram semen at +5oC. Ejaculates obtained from three mature Akkaraman rams were used in this study. Ejaculates were collected using an artificial vagina twice a week during the reproductive season. After pooling, each pooled ejaculate was split into four equal aliquots and diluted with extender with taurine 50 mM, GSH 5 mM, trehalose 50 mM and no additives. Diluted semen samples was evaluated in point of spermatozoa motility, percent abnormal spermatozoa, HOS-test result and pH at +50C for 0, 24 and 30 hours of liquid storage. It was observed that antioxidants were not effective on motility during storage at +5oC for 0. and 24. hours of storage. but trehalose provided the best protection (50.7±5.1%) for 30. hour. While taurin 50 mM ve trehaloz 50 mM gave the lowest rates (7.1±1.1% ve 7.8±0.7%) of abnormal spermatozoa at 0. hour (P<0.01), Statistical difference did not exist among the groups for 24 and 30. hours of storage. Trehalose 50 mM gave the highest results (60.0±1.2% ve 58.1±1.8%) at integrity of spermatozoon plasma menbrane at 24 and 30 hours (P<0.01). Semen pH value was lower in samples with glutathione than other groups during storage period (P<0.01). Consequently, it was observed that antioxidants added to extender provided the important contributions on spermatozoon survival at +5oC for liquid storage of semen.

Özet

Sunulan çalışmanın amacı, koç spermasının +5oC’ta kısa süreli saklanmasında antioksidanların taurin, glutatyon (GSH) ve trehalozun etkisini araştırmak olmuştur. Çalışmada üç baş ergin Akkaraman koçundan alınan eakülatlar kullanılmıştır. Ejakülatlar yetiştirme mevsiminde sun’i vajen kullanılarak haftada iki kez toplanmıştır. Alınan ejakülatlar birleştirildikten sonra dört eşit kısma bölünerek taurin (50 mM), glutatyon (5 mM), trehaloz (50 mM) içeren ve antioksidan içermeyen (kontrol) sulandırıcıyla sulandırılmıştır. Sulandırılan sperma numuneleri, +5oC’ta kısa süreli saklamanın 0., 24. ve 30. saatlerde spermatozoa motilitesi, anormal spermatozoa oranı , HOS-test sonucu ile pH yönünden değerlendirilmiştir. Çalışmada, koç spermasının kısa süreli saklanmasında (0. ve 24. saatlerde) antioksidanların spermatolojik parametrelerden motiliteyi etkilemediği, trehalozun 30. saattte en iyi korumayı (%50.7±5.1) sağladığı görülmüştür. En düşük anormal spermatozoa oranını in vitro saklamanın 0. saatinde 50 mM taurin ve trehaloz (%7.1±1.1 ve %7.8±0.7) vermesine rağmen (P<0.01), saklamanın 24. ve 30. saatlerinde gruplar arasında istatistiksel farklılık görülmemiştir. Spermatozoon plazma membran bütünlüğünün korunmasında kısa süreli saklamanın 24. ve 30. saatlerinde 50 mM trehaloz (%60.0±1.2 ve %58.1±1.8) en yüksek sonuçları vermiştir (P<0.01). Sperma pH değeri ise saklama süresi boyunca glutatyon içeren numunelerde, diğerlerine göre daha düşük çıkmıştır (P<0.01). Sonuç olarak, koç spermasının +5oC’ta kısa süreli saklan-asında sulandırıcıya ilave elden antioksidanların spermatozoon yaşamı üzerinde önemli katkılar sağladığı kanısına varılmıştır.
