AI Collection Protocols
|
1 |
Wash collection room and boar passages with clean water |
|
2 |
Ensure the collection room floor in non slippy. Place
non slip rubber mat if necessary |
|
3 |
Check collection stool has no sharp edges, is not loose and
has a properly fastened cover |
|
4 |
Ensure that two pig stock-boards are behind the safety
barriers |
|
5 |
Put the boar in the collection, room, and try to stay out
of sight. Leave him for approximately
5 minutes. Observe the boar
periodically |
|
6 |
While the boar sniffs around, put a disposable glove on
each hand and an additional loose fitting disposable glove on top of your
right hand (if you are right handed), so you have two gloves on one hand |
|
7 |
Collect the prepared collection cup. Do not touch anything whatsoever with the
single gloved hand |
|
8 |
Take extra care when entering the collection area. At this stage the boar can be
aggressive. If the boar has mounted
the stool, he will be doing thrusting movements. Place the collection cup on the shelf in
the collection room |
|
9 |
With the double gloved hand, remove any straw and dirt
from the underline of the boar. Rub his sheath and clean it out by grasping
behind the sheath and milking the hand forward |
|
10 |
Remove the top glove and throw it away |
|
11 |
Place clinched hand in front of the prepuce and lightly
rub the entrance of the prepuce to encourage him to start to erect |
|
12 |
Now reach for the cup |
|
13 |
Place the clench hand in front of the prepuce and lightly
rub the entrance of the prepuce. The
penis will erect and start to enter the clenched hand. The penis will relax and will allow the
stockperson to extend the penis. Once
fully erect the boar will settle down.
With the cup in one hand and the other holding the penis the boar
should be close to ejaculation |
|
14 |
The first stage will be gel and some cloudy fluid |
|
15 |
Then a clean fraction will flow. The first ejaculations
should be discarded to wash out the urethra. Further ejactulations should be collected followed by a milky
coloured fraction, known as sperm rich and then another clear fraction will
follow. All of this may be collected |
|
16 |
Finally, another gel fraction will be produced, this
should be collected |
|
17 |
During the collection of semen you may get preputial fluid (from the sheath) trickling down the
penis, this will kill the semen. You
can wrap a folded tissue around the penis during collection to avoid
this. In additional having a kink in
the penis just before the collection cup will prevent any preputial
trickle entering the cup |
|
18 |
Aim to keep the tip of the end of the penis in the pool of
semen held by the gauze to keep the tip warm |
|
19 |
Continue to hold the penis until the boar withdraws his
penis from your hand. The end of
ejaculation is often determined by a bouncing of the penis. Be very careful of contamination |
|
20 |
The whole collection process takes from |
|
21 |
Now throw away the gauze and gloves into the bin provided |
|
