Use of B-mode, linear array ultrasonography for evaluating the technique of bovine artificial insemination.
B-Mode, linear array ultrasonography was used to evaluate the site of semen deposition in live cows. The insemination sheath was modified to hold a brass bead that was deposited at the simulated site of semen deposition. The position of the bead was identified by ultrasonography and the bead was recovered by pulling a nylon line that was attached to the bead. An ultrasound technician identified placement of the bead in the site designated for semen deposition by a skilled inseminator in 24 of 25 cases. This procedure improves methods for inseminator training by providing a method of evaluating insemination technique using live animals rather than excised reproductive tracts. The ultrasound equipment used for inseminator evaluation is affordable, portable, and does not pose a human health risk.
