When considering artificial insemination, you will need to think about the type of semen you will use and the method of insemination. The types of semen that can be used are fresh, chilled and frozen. The type of semen and method to be used will determine when to inseminate the bitch.
Types of Semen :
- Fresh- stud dog is present
- Chilled- semen is collected elsewhere, cooled down and stored
- Frozen- semen has been collected, frozen and stored
Methods of Insemination : Some methods work better with certain types of semen than others
AI (MAVIC) :
Semen is inserted vaginally using a catheter with a balloon that
inflates. This balloon simulates what would be the “natural tie”
in natural dog breedings. This is beneficial because it causes
uterine contractions which pushes the semen to the oviducts and
prevents backflow. The semen is deposited near the cervix. This
method is not recommended with frozen semen.
Semen is inserted vaginally using a TCI scope that delivers the
semen directly through the cervix into the uterus. This method can
be used with fresh,chilled or frozen semen.
- Surgical Insemination : For this method, anesthesia is required so that an abdominal incision can be made and semen is deposited into both uterine horns. This method can be used for all types of semen, and is recommended when using frozen semen, semen with unknown quality, and for females who have been previously infertile. Progesterone timing is very important with this type of insemination to ensure the success of a breeding, and to maximize conception and litter sizes.
