Koç spermasının +4 C⁰’de saklanmasında gallik asitin spermatolojik parametreler üzerine etkisi

saklanmasında sulandırıcıya farklı oranlarda ilave edilen Galik asitin etkilerinin ortaya konması amaçlandı. Gereç ve Yöntem: Çalışmada Burdur Çallıca kasabasında bulunanözel bir koyun işletmedeki 4 baş Merinos koç (2-3 yaş) kullanıldı. Çalışma süresince koçlardan sperma elektro-ejekülatör yardımıyla haftada iki kez olmak üzere elde edildi. Toplanan ejkülatlardan spermatozoa motilitesi %80>, yoğunluğu 0 mM (kontrol) ile 1.5x10⁹ spermatozoa/ ml üzerinde olanlar pooling yapıldı ve deney grupları oluşturuldu.Deney grupları sırasıyla antioksidan içermeyen (kontrol), 2 mM, 5 mM ve 10 mM dozlarında gallik asit içeren sulandırıcı grupları olacak şekilde belirlendi ve +4 C⁰’de saklandı. Grupların oluşturulmasında sonra 24 saat aralıklar ile 96 saat süresince subjektif motilite (%), morfolojik (%) ve membran bütünlüğü (HOS test, %) bakımındandeğerlendirildi.Bulgular: Çalışmada 48. saatin sonunda kontrol grubuna (%51.0±2.7) göre en yüksek motilite Gallik asit 2 mM (%72.7±5.3) ve 5 mM (%69.4±4.8) içeren sulandırıcı gruplarından elde edildi (P

Effect of gallic acid on ram semen spermatological parameters at +4 ⁰C storage

Aim: The purpose of this study was to investigate the effect of different rate of gallic acid on ram semen liquid storage in non-breeding season. Materials and Methods: In this study, four Merino rams (2-3 ages) were used and belonging to the special sheep farm in Callica, Burdur/ Turkey. Ejaculates were collected from the rams using a electroejaculator, the ejaculates containing spermatozoa with >80% motility and concentrations higher than 1.5x10⁹ spermatozoa/ml were mixed and used in the study. The mixed ejaculates were divided into four equal aliquots and samples were extended with tris containing 0 mM (control), 2 mM, 5 mM, 10 mM gallic acid and they were stored at 4°C. After the groups were created, sperm motility (%), morphologic integrity (%), membrane integrity subjective (Hipo Osmotic Swelling Test, HOS test, %) were examined 24 hour intervals until 96 hour. Results: The highest motility at 48. hour was seen gallic acid 2 mM (72.7±5.3%) and 5 mM (69.4±4.8%) groups compared the control (51.0±2.7%) group (P
