The effect of transcervical intrauterine and intravaginal insemination methods on fertility in dogs

摘要

This study was carried out to determine the effect of transcervical and intravaginal artificial insemination on the pregnancy rate in dogs. Semen was collected by the massage method from dogs brought to our department. Collected semen was examined in the laboratory and stored in liquid nitrogen after dilution with Tris extender. During the study 31 bitches brought to our department for artificial insemination were used. One of the bitches was not evaluated. Oestrus was detected by vaginal cytologyand the bitches were inseminated twice during the oestrus period. Fifteen of the 30 bitches were inseminated transcervically and the other 15 intravaginally. The pregnancy rate was 60.00% with the transcervical insemination method and 26.66% with the intravaginal insemination method (P < 0.05). In conclusion, we have detected that transcervical insemination with frozen dog semen is more effective than intravaginal insemination in terms of fertility.
