The aim of this research was to prove principal spermatological characteristics by invitro data in Ross breeder cocks and expose factors effected semen quality. In this experiment 5 Ross breeder cocks were treated. During the research, semen was collected from cocks by manual message method twice a week. The spermatological characteristics of ejaculates from cocks are as follows: (1) Ejaculate volume averaged 0.3 0.0 ml (2) sperm motility 72.1 5.9 %, (3) sperm concentration 3.0 1.9 x 10**deg/ml, (4) percentage of abnormal sperm 4.8 0.7 % and (5) pH 7.5 01. Fresh semen was performed the thermorezistens test. During the incubation at 40 deg C, it was observed that sperm motility ceased at 240 minutes
