Preparation for
service
When training tick off |
||
|
1 |
Remove
the boar from sight and sound of
the sow for at least one hour prior to breeding |
|
|
2 |
Parade a
boar in front of the
female outside the pen. If the signs of oestrus are demonstrated sit on her back and prove she will stand still |
|
|
3 |
Only
inseminate females which demonstrate "standing reflex" |
|
|
4 |
Wipe
vulva clean with a dry tissue. If the vulva
is clean do not clean with tissue |
|
|
5 |
Place
gloves on both hands |
|
|
6 |
Select
semen bottle by checking it is the required boar |
|
|
7 |
Mix
settled semen by gently rotating bottle (top over bottom 6 times) then place mixed
semen in overall top pocket |
|
|
8 |
Wipe
clippers clean with dry tissue and put clean clippers in overall top pocket |
|
|
9 |
Take
a new catheter. Do not use any
catheter which is not clean. You do
not need to lubricate a foam tipped catheter. If you do, avoid applying the lubricant to
the hole |
|
|
Insemination
procedure |
||
|
1 |
Part
vulva lips and gently insert catheter into vagina forwards and upward to
prevent catheter entering bladder |
|
|
2 |
Push the
catheter straight forward until the ridges of the cervix are felt. Do
not twist. Do not rotate a foam tipped catheter |
|
|
3 |
Take
semen from pocket, gently rotate (top over bottom once), cut top 1 cm off
spout |
|
|
4 |
Insert
semen bottle firmly into catheter.
Apply gently pressure to the bottle to prime the catheter. Keep bottle at an upwards angle of about 30• |
|
|
5 |
Use
free hand to rub female flanks, and apply back pressure during insemination
to stimulate and maintain standing still reflex |
|
|
6 |
Allow
the female to draw semen, Apply gentle
pressure on the bottle to overcome vacuum pressure It may be necessary to remove bottle half way
through to allow air back into bottle to release vacuum pressure |
|
|
7 |
If
any leak back occurs, stop inseminating immediately, remove bottle from
catheter. Re-lock catheters and start
again. If excessive leak back occurs
it many be best to re-inseminate with another bottle of semen or serve using
the boar |
|
|
8 |
When
bottle empty slowly remove catheter by rotating clockwise |
|
|
19 |
Record
service and score quality of service |
|
|
10 |
If this
is the first insemination, re-inseminate 24 hours later if the female passes
the standing reflex |
