Possible association between age and reproductive parameters in Akkaraman rams during breeding season

Öz:
Bu çalışma aşım sezonundaki 2 ve 4 yaşlarındaki 10 adet Akkaraman koç üzerinde yapılmıştır. Klinik olarak (testis uzunluğu ve kalınlığı, scrotum çevresi, scrotum hacim ve kalınlığı ve reaksiyon süresi), spermatolojik olarak (sperma hacmi, viskozitesi ve pH'sı, kitlesel hareket ve spermatozoa motilitesi, spermatozoa yoğunluğu ve anormal spermatozoa oranı) parametreleri ve testosteron düzeyleri araştırılmıştır. Testisin morfometrik ölçümlerinde yaş grupları arasındaki fark önemli (P<0.05) bulundu. Spermanın viskozite ve pH'sı, spermatozoonların kitlesel hareketleri ve testosteron düzeyleri arasında fark gözlenmezken diğer parametreler yönünden yaş grupları arasındaki fark önemli (P<0.05) bulundu. Scrotum çevresi ile reaksiyon süresi (r:-0.90), sperma viskozitesi (r:-0.82) ve spermatozoa motilitesi (r:-0.81) arasında negatif (P<0.01) yönde ilişki gözlenirken scrotum hacmi (r:0.65) ile pozitif (P<0.1) yönde ilişki gözlendi. Spermatozoa motilitesi ile sperma miktarı (r:-0.89), pH (r:-0.85) (PO.05), sağ testis kalınlığı (r:-0.73) (PO.01) ile negatif yönde ilişki gözlenirken viskozite (r:0.93) (PO.01) ile pozitif yönde ilişki tespit edildi. Ayrıca sperma viskozitesi ile sol testis uzunluğu (r:-0.66) ve sağ testis kalınlığı (r:-0.92) arasında negatif yönde ilişki gözlendi. Anormal spermatozoa oranı ile scrotum kalınlığı (r:0.87) (P<0.01) arasında pozitif yönde ilişki gözlenirken scrotum hacmi (r:-0.81) ile negatif (P<.01) yönde ilişki tespit edildi. Testosteron düzeylerinin sperma miktarı (r:0.82) ile pozitif, kitlesel hareket (r:-0.81) ve motilite (r:-066) ile negatif yönde ilişkili olduğu belirlendi.

The study was carried to investigate the possible association between age and reproductive parameters in rams. Ten Akkaraman rams aged 2-4 years were used during the breeding season. Animals were allocated into two groups (aged 2 and aged 4) and following parameters were examined: lenght and thickness of testes, scrotal circumference, volume and thickness of sac, and reaction time; volume, viscosity and pH values of semen, mass activity and motility of spermatozoa, sperm concentration and abnormal sperm rate, and testosterone levels. Morphometric measurements of testes significantly differed between age groups (P<0.05). Although the viscosity and pH of semen, mass activity from spermatological parameters and testosterone levels indicated no differences, other parameters were significantly differed between age groups (P<0.05). Scrotal circumference was negatively associated with reaction time (r:-0.90), semen viscosity (r:-0.82), and motility (r:-0.81) and positively associated with scrotal sac volume (r:0.65). The motility was negatively correlated with ejeculate volume (r:-0.89), pH (r:-0.85), and thickness of the right testes (r:-0.73), but positively associated with viscosity (r: 0.93). It was also observed that the viscosity was negatively correlated with length of the left testes (r:-0.66) and thickness of the right testes (r:-0.92). Abnormal sperm rate was positively associated with scrotal thickness (r:0.87) but was negatively correlated with scrotal sac volume (r:-0.81). There was a positive correlation between ejeculate volume (r:0.82) and testosterone levels. However negative correalation was seen between masss activity (r:-0.81) and motility (r:-0.66 with mass).
