Because the reproductive tract is freely movable, cows that have strong rectal and
abdominal contractions in response to being palpated may actually push their reproductive
tract back into the pelvic cavity.
This will cause many folds to form in the vagina.
In such cases, the insemination gun will often get caught in these folds and little
or
no progress will be made until they are removed. If you can locate the cervix, grasp it
and
push it forward. This will straighten the vagina and the gun should pass freely up
to
the cervix. If you cannot locate the cervix, encircle the gun tip with your thumb and
forefingers.
With a straightening motion of your wrist, gently “milk” the folds out of the
vagina
a little at a time. Slide the gun forward and repeat the process until the cervix
is
reached.
