Radiographic method for evaluation of bovine artificial inseminating technique.

Radiography was used to visualize the interior of excised bovine reproductive tracts during artificial insemination. Reproductive tracts were placed in a device that simulated the anatomical position of the reproductive organs in vivo. Air was introduced into the uterus to provide differential radiopacity between the uterine lumen and the surrounding soft tissue. Egg yolk extender was saturated with lead acetate to provide radiopacity, thus enabling the inseminate to be visualized following deposition. This radiographic technique enables the insemination syringe tip and the distribution of the inseminate within the reproductive tract to be visualized clearly without dissection.
