Boğa Spermalarının İki Farklı Sulandırıcı ile Dondurulması ve İn Vitro Değerlendirilmesi Freezing of Bull Semen with Two Different Extenders and In Vitro Evaluation
TUNCER, Pürhan Barbaros
In this study effect of AndroMed (AS) and Laiciphose W 488 (LS) extenders on the sperm motility and abnormal spermatozoa rates was examined in Holstein bull semen after they were diluted equilibrated and, thawed. In the study 40 ejaculates collected from 4 bulls were used. Averaga semen volume (8.47±0.69%), sperm concentration (x106/ml) 1030.55±7.11, and abnormal spermatozoa (3.47±0.18%) were found. The motility rates of fresh semen and after equilibration that diluted with LS and AS were 83.37±0.37%, 73.50±0.80% and 83.12±0.38%, 72.25±0.83% respectively. After thawing motility rates of sperm diluted with LS and AS extenders were 54.63±1.47%, 52.75±1.16% and, abnormal spermatozoa percentages of the sperm were 7.75±0.34% and 8.25±0.30%. According to this study, neither of these extenders a...
Evaluation of Some Spermatological Characteristics in Denizli Cocks
Tuncer, P. B.
The aim of this research was to prove the principal spermatological characteristics by in vitro datas in Denizli cocks in Turkey. In this experiment, 31 Denizli cocks were used. Semen was collected from cocks by abdominal massage method, two times a week. The spermatological characteristics of samples are as following: Ejaculate volume average 0.70±0.01 ml, spermatozoa motility 72.32±0.80%, spermatozoa concentration 2.38±0.03x109/ml, percentage of abnormal spermatozoa 7.33±0.18%, percentage of live-dead spermatozoa 21.65±0.81% and pH 7.68±0.01. Acrosome, head, middle piece and tail deformations of 558 ejaculates had been collected were recorded as average 0.62±0.04%, 1.34±0.05%, 2.47±0.05% and 2.89±0.08%, respectively.
