Solution |
The sow will
not stand still during the insemination process |
She is not in
'standing oestrus'. If she is in
oestrus but not standing, remove from boar contact and retry one hour later,
with another boar |
The semen
does not flow freely |
Withdraw the
catheter slightly as its end may be against the wall of the cervix |
Remove the
catheter and check the hole in the end |
|
There is
excessive leak back of semen out of the vulva while inseminating |
The inseminator
may be trying to proceed too quickly |
The sow may not
be on heat properly |
|
The sow may not
have been stimulated properly |
|
The catheter
may not be in far enough |
|
The catheter
does not lock properly |
In older sows
the cervix is too relaxed and dilated. A catheter with a bulbous end may be
useful |
Urine pours
out of the end of the catheter |
Accidental catherisation of the bladder. Urine will harm the sperm cells so a fresh
catheter should be used. Inject the
sow with a single injection of a suitable antibiotic |
The sow has
urinated while inseminating |
Do not stop the
insemination and do not remove the catheter until the insemination has
finished. Record the incident |
The sow has
an abnormal vulval discharge |
Record on the
insemination sheet,
If noted prior to insemination do not inseminate. If you must mate the sow use a boar and
then treat his sheath with an antibiotic.
Now change gloves and wash your hands |
It is the
weekend and I have not done any AI before |
Do not start
now. Mate with a boar. Enrol on a course of tuition |
I am having
problems with the insemination technique |
Mate with a
boar and discuss your problems with your veterinarian or an AI centre |
