Breed differences in the position of the urethral meatus of gilts.
In a strain of Pietrain the distance between the vulva and the urethral meatus is greater than that of other breeds of pig. This difference is such that it is difficult to catheterise the bladders of Pietrain gilts since the available specula are either too short in length or too wide in diameter.
