ABSTRACT
The aim of the study was to compare fertility data obtained from bitches after vaginal vs. transcervical intrauterine endoscopic insemination with frozen-thawed semen. The experiment was carried out on 34 bitches divided into two groups. Vaginal insemination using bovine infusion pipette was performed in the group 1 of bitches. Transcervical insemination of semen direct into uterine lumen after visualisation of cervical portion was performed in the group 2 of bitches. Semen of 14 stud dogs was used in the study. Whelping rates in group 1 and 2 were 27.8% and 68.7%, respectively (p<0.05). Mean litter sizes at birth/mean litter sizes at weaning were significantly higher (p<0.05) in group 2 of bitches (4.9 ±1.7/4.6 ±1.7) than in group 1 of bitches (3.0 ±1.2/2.6 ±0.9). The present study showed successful results of trancervival endoscopic technique of insemination of bitches with frozen-thawed semen. Fertility and fecundity indices obtained in this study are encouraging and make opportunity for widen use of frozen-thawed dog semen for insemination of bitches in routine veterinary practice.
Key words: bitch, dog, insemination, semen, cryopreservation.
