Abstract
In this experiment, some andrological examinations of 18 Arabian race stallions aged from 8 to 12 and removed from races were performed for using as stud. For this purpose, employability of stallions as a stud was investigated by testing of libido sexualis and sexual behaviours and determining of spermatological parameters. Libido sexualis, sexual behaviours (coming, mounting, clutching and ejaculation) and accomodation to artificial vagina of stallions were evaluated from 0 to 5 in the presence of a oestrus female. Three ejaculates from each stallion were collected on consecutive days using an artificial vagina and totally 54 ejeculates were evaluated. In collected ejeculates, semen volume, motility, live sperm, abnormal sperm, and pH values were determined. Examined 18 stallions were evaluated as 4 stallions were normospermic, 12 stallions were disspermic, a stallion was necrospermic and the ejaculate from a stallion could not been collected. According to obtained results, the stallions removed from races immediately afterwards would not use as a stud. It was concluded that they would show libido sexualis and collected semen depend on individual properties of stallions by collection of semen orderly, improvement of care and feeding conditions and adaptation to environment

Abstract
Bu çalışmada, yaşları 8-12 arasında değişen ve yarışlardan çıkarılmış 18 safkan Arap ırkı aygırın damızlık olarak kullanılması amacıyla bazı androlojik muayene ve değerlendirmeler yapılmıştır. Bu amaçla cinsel istekleri ve aşım davranışları test edilerek, spermatolojik parametreleri saptamış damızlık olarak kullanılabilirlikleri araştırılmıştır. Aygırların östrusdaki bir kısrak varlığında gösterdikleri cinsel istek (libido sexualis), aşım davranışları (yaklaşma, atlama, kavrama ve yüklenme) ve sun’i vaginaya uyumları 0-5 arasında puanlanmıştır. Onsekiz aygırın herbirinden birbirini takip eden günlerde olmak üzere suni vagina ile üç kez ejakülat alınmış ve toplam 54 ejekülat muayene edilmiştir. Alınan ejekülatlarda sperma miktarı, spermatozoa motilitesi, spermatozoa yoğunluğu, anormal spermatozoa oranı, ölü spermatozoa oranı ve sperma pH değerleri saptanmıştır. Muayene edilen 18 aygırdan 4’ ü normospermik, 12’ si disspermik, 1’ i ise nekrospermik olarak değerlendirilmiştir. Bir aygırda cinsel istek ve aşım davranışını gözlenmemiş ve sperma alınamamıştır. Elde edilen sonuçlara göre, aygırların yarışlardan çıkarıldıktan hemen sonra damızlık olarak kullanılamayacağı, ancak düzenli aralıklarla sperma alınması, bakım ve besleme koşullarının iyileştirilmesi ve ortama adaptasyonları sonucunda bireysel özelliklere bağlı olarak cinsel istek gösterebilecekleri ve sperma alınabileceği sonucuna varılmıştır
