Misc. Breeding Services
Caslicks Procedure
A procedure named
after E. A. Caslick DVM. He discovered air had an
effect on broodmares maintaining a pregnancy. This
is because the mare acquires an infection that makes
the uterus an unfavorable place to carry a foal.
Surgically closing the upper part of the vulva has
been commonly practiced on broodmares for 60 years.
The vulva is normally vertical and has a good seal
to prevent contamination. Conformation abnormalities
can be genetic or due to injury during previous
births. This procedure is quick and simple and
usually done from 15 to 30 days after breeding. It
heals closed and remains in place until a month
before the mare is due to foal when Dr Winter can
surgically cut it open. If the mare foals with a
caslicks in place, a lot of damage can occur and the
birth is very difficult.
Recto-Vaginal Tear
During the foaling
process, if the foal does not present correctly,
damage can occur. This damage can be mild, such as
bruising or abrasions, or severe and cause permanent
problems. When a recto-vaginal tear occurs, the
tissue separating the rectum from the vagina tears
open and allows fecal material into the vagina. If
this injury is not corrected soon after the
incident, it can heal and leave scar tissue forever
complicating reproductive abilities. When the
anatomy is dramatically changed its ability to
perform its job is lost. The vagina no longer has a
good seal to protect the uterus from infection and
the rectum no longer has good tone to hold fecal
material within the body. This is a surgery that
requires an experienced practitioner who is familiar
with the equine reproductive anatomy. Dr. Winter has
performed the procedure numerous times and is
confident in his abilities.
Retained Placenta
After foaling a mare
should “clean” or deliver the placenta within 3
hours. If a retained placenta is not removed, the
milk production may be affected. The mare may
develop a fever which could result in founder and a
uterine infection may develop as well. Dr. Winter
may sedate the mare (if needed), and give an
injection to induce uterine contractions which
results in the release of the placenta. If needed,
he applies gentle downward pressure on the remaining
placenta to slowly pull it out. After removing the
membranes, he will flush the uterus with a lavage
solution.
