Abstract

This study was conducted to investigate the possible protective effect of ?-lipoic acid (ALA) supplementation to extender on damages in the quality of bull semen elicited by freze-thawing process-induced oxidative stres. Ejaculates were collected via an artificial vagina from the bulls at once a week. Then they were split into five aliquots and extended with the Tris base extender containing different doses of ALA, except control. The extended samples were equilibrated slowly to 4°C for 4 h and then frozen using a digital freezing machine. Frozen straws were thawed to analyse progressive motility and sperm motility characteristics as well as plasma membrane integrity. Biochemical assays were performed in a spectrophotometer using commercial kits. Treatment of extender with ALA groups caused a significant decrease in percentages of post-thaw sperm CASA, progressive motilities and sperm motility characteristics such as VAP, VSL and VCL except ALA0.5. Besides ALA0.5 showed lower percentages of acrosome and total abnormalities in comparison to the control. In conclusion, findings generated here showed that ALA0.5 supplementation in Tris based semen extender was of great beneficial effect on frozen-thawed bull semen in terms of morphology and plasma membrane integrity

Özet

Bu çalışma dondurma-çözündürme işleminin neden olduğu oksidadif stresden dolayı boğa spermasında meydane gelen hasarlar üzerine sulandırıcıya katılan ?-lipoik asidin (ALA) muhtemel koruyucu etkisini araştırmak amacı ile yapıldı. Ejakülatler haftada bir kez olmak üzere suni vajen yardımı ile toplandı, sonrasında beş eşit parçaya ayrıldı ve kontrol grubu dışında diğerleri farklı dozlarda ALA içeren Tris bazlı sperma sulandırıcısı ile sulandırıldı. Sulandırılan spermalar 4°C'de 4 saat süre ile ekülibre edildi ve otomatik sperma dondurma cihazı kullanılarak donduruldu. Dondurulan spermalar çözündürülerek plazma membran bütünlüğünün yanı sıra spermanın ileri yönlü hareketi ve sperma hareket özellikleri değerlendirildi. Biyokimyasal analizler ticari kit kullanılarak spektrofotometre de yapıldı. ALA0.5 grubu dışında ALA ilave edilmiş sulandırıcı ile sulandırılan gruplarda dondurma çözündürme sonrası CASA ve ileri yönlü spermatozoa hareketi ile VAP, VSL, VCL (spermatozoonun tüm hareketlerinin ortalaması, spermatozonun ilk harekete başladığı ve hareketini sonlandırdığı yer arasındaki en kısa mesafe, gerçek eğrisel yolda kat ettiği mesafe) gibi spermatozoa hareket özellikleri üzerine olumsuz etki gösterdi. Bunun yanında, kontrol grubu ile karşılaştırıldığında ALA0.5 akrozom ve total anormalitenin daha düşük oranlarda olmasını sağladı. Sonuç olarak, bu çalışmada elde edilen bulgular Tris bazlı sperma sulandırıcısına ilave edilen ALA0.5'in morfoloji ve plazma membran bütünlüğü üzerine olumlu etkilerinin olduğunu gösterdi
