A quick outline of steps for use.
1 Heat check and put the boar away. This will stimulate the females into standing heat.
2 Wait 20-30 minutes. The delay will allow the female to cycle into refractory heat.
a. Standing heat starts the cervical contractions.
b. After 20-30 minutes the contractions will continue but will become weak allowing the diaphragm to traverse the cervix more easily.
3 Lubricate the foam tip of the catheter.
4. Load the catheter in an upward motion into the cervix with a good push and a twist in the female to be bred. (If breeding in crates you can load the catheter in up to 10 females and then move to the next step.)
5 Pull back on the catheter to straighten the cervix.
6 Hold the catheter at the base of the vulva. This will keep the catheter from moving if the female moves during insemination. If the catheter moves, you will potentially have the foam tip of the catheter up against a fold preventing the diaphragm from deploying.
7 Attach the bottle / tube / bag squeeze the bottle / tube / bag quickly. This will deploy the diaphragm through the cervix.
8 After insemination tip the catheter in a downward motion with the bottle / tube / bag still attached. If the diaphragm did not deploy semen will run back into the bottle / tube / bag. No run back then insemination is successful.
9. Remove the catheter from the female by pulling back on the catheter.
