Abstract

This study was conducted to investigate the seasonal changes in serum testosterone levels and spermatological characteristics in Akkaraman rams. In this investigation, 120 Akkaraman rams, which were brought to the slaughterhouse for slaughtering and whose ages ranged between 14-18 months, were used. Semen was collected by an electroejaculator. Volume, motility, concentration and rate of abnormal spermatozoa were determined in collected semen. Blood samples were taken from jugular vein and centrifuged at 5000 rpm for 10 minfor serum extraction. The amount of testosterone was determined by coated tube RIA method using the serum stored at deepfreeze at -20°CÎ. While the highest annual values of semen volume, sperm motility, sperm concentration and testosterone were determined as l.ll±0.03 ml, 84.66±1.01%, 3.21±0.07xl09/ml and 6.35±0.16 ng/ml respectively in September. The lowest values of these parameters were determined as 0.56±0.03 ml, 63.32±0.99%, 2.03±0.06xl09/ml, 2.69±0.08 ng/ml respectively, in February. Semen volume, sperm motility, sperm concentration and amount of testosterone reached their maximum levels in autumn and minimum levels in winter. Variations of these parameters among months, seasons were statistically significant (p

Özet

Bu çalışma Akkaraman koçların serum testosteron düzeyleri ve spermatolojik özelliklerindeki mevsime bağlı değişiklikleri araştırmak amacıyla yapılmıştır. Bu araştırmada mezbahaya kesilmek üzere getirilen 14—18 aylık, 120 Akkaraman koç kullanıldı. Sperma koçlardan elektroejakülatörle alındı. Alman spermada miktar, motilite, yoğunluk ve anormal spermatozoon oranları belirlendi. Vena jugularisten alınan kan örnekleri 5000 rpm'de 10 dak. santrifüj edilerek serumları çıkarıldı. Derin dondurucuda -20°C'da saklanan serumların Coated Tube RIA metoduyla testosteron miktarı tayin edildi. Yıl içerisindeki en yüksek ortalama sperma miktarı, spermatozoon motilitesi, spermatozoon yoğunluğu ve testosteron miktarı sırasıyla; 1.11±0.03 mi, %84.66±1.01, 3.21±0.07xl09/ml ve 6.35±0.16 ng/ml ile Eylül ayında tespit edildi. Bu parametrelere ilişkin en düşük değerler ise sırasıyla 0.56±0.03 mi, %63.32±0.99, 2.03±0.06xl09/ml ve 2.69±0.08 ng/ml ile Şubat ayında bulundu. Sperma miktarı, spermatozoon motilitesi, spermatozoon yoğunluğu ve testosteron miktarının sonbaharda en yüksek, kış mevsiminde ise en düşük düzeyde olduğu tespit edildi. Bu parametreler yönünden mevsimler ve aylar arasında gözlenen farklılıkların istatistikî açıdan önemli (p
