ResumoFour experiments were conducted to study the anatomical structure of the ovine cervix and to investigate a quick non-surgical intrauterine insemination into the uterus using carbon dioxide (CO2)gas in the reproductive tract. In Experiment 1, the types of the cervical orifice were classified by the method of Dun (1) (Fig 5) and it was found that types 6 and 8 (Fig.1 b & e) had significant difference in the rate of successful penetration through the cervical canal at the 5% level compared with the other three types. In Experiments 2, 3 and 4, using abattoir specimens, the technique with CO2 gas shortened times required for intrauterine insemination, as there was no need to penetrate the whole length of the cervical canal. The use of CO2 gas should be investigated in live animals for a quick method of non-surgical intrauterine insemination.
