Özet
The aim of current investigation was to evaluate seasonal changes in the testicular measurements, fresh and post-thawing spermatological characteristics, serum testosterone (T) levels in Gurcu goats. Moreover, seminal plasma phospholipase A(2) activity levels were determined. Four adult Gurcu male goats (2-3 years old) were used as semen donor and ejaculates (n=113) from these goats were weekly collected with artificial vagina in the presence of natural estrus or estrogened female fantom during breeding season (BS, September-February) and non breeding season (NBS, March-August), respectively. Moreover, jugular blood was collected and serums were separated to determine Testesterone level during BS and NBS. All andrologic parameters, except testes width (P<0.05), were not changed statistically during BS and NBS in Gurcu bucks. It was determined that ejaculate volume (1.27 +/- 0.05 vs 0.76 +/- 0.04mL; P=0.001), fresh progressive sperm motility (80.39 +/- 1.00 vs 74.43 +/- 2.26%; P=0.019) were significantly higher in BS compared to NBS, respectively. However, sperm concentration (3.93x10(9) vs 2.48x10(9) spermatozoa/mL; P=0.001) was interestingly higher during NBS compared with BS, although total number of sperms per ejaculate were similar during BS (3.03x10(9) spermatozoa/ejaculate) and NBS (2.93x10(9) spermatozoa/ejaculate), P>0.05. Also there was no differences in post-thaw progressive sperm motility between BS and NBS (25.0 +/- 2.86 vs 19.32 +/- 2.55%; P=0.145). T did not any show significant change between BS and NBS (13.44 +/- 2.37 vs. 13.06 +/- 1.18 ng/mL). Although seasonal changes were …
