Abstract

Bu çalışmanın
amacı, 7-dehidrokolesterol yüklenmiş siklodekstrinin (7-DCLC) +4 C⁰’de kısa süreli saklanan koç spermasının spermatolojik
parametrelerine etkisinin araştırılmasıdır. Her bir
hayvandan spermalar elektroejakülatör yardımı ile sezon dışında alınarak dört eşit gruba ayrıldı, farklı oranlarda 7-DCLC (1,5 mg, 3,0 mg and 5
mg/120x10⁶)  içeren ve
içermeyen kontrol (C) tris/yumurta sarısı sulandırıcı ile sulandırıldı.
Sulandırılan spermalar, +4 C⁰’de saklanarak 96 saat süresince motilite, membran bütünlüğü ve anormal
spermatozoa yönünden incelendi. Saklama süresi boyunca anormal spermatozoa
yönünden gruplar arasında bir farklılık bulunmazken (P>0,05); motilite
açısından gruplar arasında farklılıklar tespit edildi (P<0,05).  72. ve 96. zaman dilimlerinde en yüksek
motilite 7-DCLC 1,5 mg/120x10⁶ grubunda tespit edildi (P<0,05).
En yüksek dozlu (5 mg) 7-DCLC grubu diğer gruplarla karşılaştırıldığında
spermatozoa motilitesini ve membran bütünlüğünü düşürdüğü tespit edildi.
Ayrıca, 72. saatte 7-DCLC 3,0 mg grubunun membran bütünlüğü kontrol grubuna
göre daha az olduğu tespit edildi (P<0,05). Sonuç olarak, 7-DCLC 1,5 mg
içeren tris/yumurta sarısı sulandırıcısı koç spermasında motiliteyi ve membran
bütünlüğünü +4 C⁰’de 96 saat süresince koruduğu belirlendi.

Effect of 7-Dehydrocholesterol on Ram Semen Spermatological Parameters on Short Term Preservation

Abstract

The aim of this study
was investigated to effect of 7-dehydrocholesterol loaded cyclodextrin (7-DCLC) on ram semen
spermatological parameters on short term preservation at +4 ⁰C. Collected semen with electroejaculator at non-breeding
season. Each animal native ejaculates were mixed and divided into 4 equal groups, diluated with tris/egg yolk extender
with included different rates of 7-DCLC (1.5 mg, 3.0 mg and 5 mg/120x10⁶)
and control (C). After extended semen samples were preservation at +4 ⁰C and evaluated motility, membrane integrity and
abnormal spermatozoa rate until 96. hour. There were no significant differences
between the groups on abnormal spermatozoa rate (P>0.05); there were a
significant differences between the groups on motility at all storage period
(P<0.05).The highest motility were observed in 7-DCLC 1.5 mg at 72. and 96.
hour (P<0.05).  The highest dose (5
mg/120x10⁶) 7-DCLC were decreased the motility and membrane
integrity compared to other groups. Besides, 7-DCLC 3.0 mg group membrane
integrity was lower than control at 72. hour (P<0.05). In conclusion, tris/egg yolk extender which is contain 7-DCLC 1.5 mg
were protected to ram semen motility and membrane integrity up to 96. hour at
+4°C preservation.
