The objective of this study was to investigate the feasibility of use of cervical artificial insemination (CAI) method in Karya sheep breed. Planning the mating plans and controlling the inbreeding may be possible with the use of effective artificial insemination techniques. In the present study, 89, 16 and 85 ewes showing estrus were cervically inseminated with diluted fresh semen from 13, 4 and 9 head rams at 2005, 2007 and 2009 mating seasons, respectively. Data were evaluated with respect to gestation length, litter size and AI success rate. The least square means for mentioned traits were found as 147.61 days, 1.73 and 57.30% for 2005 lambing season and 148.57 days, 1.71 and 43.80% for 2007 lambing season and 147.53 days, 1.47 and 50.59% for 2009 lambing season respectively. The difference between means of years were not statistically significant (P> 0.05) for all the evaluated variables except gestation length and litter size. These results have been close to the values indicated in the literature. Our results show that cervical insemination will be a useful tool in field conditions.
