Step 1:
Identify the female in standing heat. Provide face-to-face contact with a mature, "ranty" boar.

• If necessary, clean the vulva with a soft paper towel.
• Lubricate the catheter tip with a small amount of sterile, water soluble, nonbactericidal lubricant.
• Standing on the left side of the female, facing backwards, use left hand to spread the vulvula lips, insert the catheter about 3 to 4 inches.
• Reposition yourself to the rear of the female.
• Position the catheter at a 20 to 30 degree angle with the tip pointed upwards. Gently push forward and backward until the tip is about 4 to 6 inches forward. (This will avoid entering the urethral [bladder] opening.)

Step 2:
Position the catheter more horizontally and continue to gently move it forward until resistance is felt. This should indicate that the tip is at the cervical opening.

• Gently rotate the catheter counter-clockwise as the cervix is entered. Obtain a firm lock which is indicated when the catheter feels tight and will spring back about 1/4 turn. Do not force it too much.

Step 3:
Connect the bottle/tube to the shaft of the catheter and hold in an upright position. Initiate semen flow by application of gentle pressure on the bottle/tube. Gentle, alternating movement of the catheter may enhance flow of semen. Stimulate the female via back pressure, rubbing the underline and flank area. Be patient, some females will "take" the semen with little or no pressure being applied to the bottle/tube, while others may require alternating pressure on the bottle/tube. Allow 2 1/2 to 3 minutes, minimum, per female. Some require more time than others. DO NOT RUSH.
