Boar Training and Semen Collection
Boar: Age, Condition, Overall Attitude
Boars that are 7-8 months of age and have been exposed to some sexual
activity by running in groups with other males are ideal for training to collect off a
dummy (age of sexual maturity may differ with breed and genetics.)
Older boars, especially those used in pasture breeding situations, and
young boars that have been isolated, usually will take more time to train. The boars should be in good physical and nutritional condition - not
over or under fed.
Take note of the boar's personality. Any problems or quirks that have
been exhibited in the past might need to be remembered while training.
Collection Dummy: Wood, Portable, Stationary, Wall Mount
Construction: Any article or material that would
somewhat resemble a sow can be used to construct a dummy.
-
Wood or steel are most often used for construction. A very economical
dummy can be constructed using 2 x 4s or 2 x 6s. Another alternative is one-half of a hot water tank for the body of
the dummy.In an emergency, a bale of straw or similar article can be used as a
dummy.Approximate dimensions of the body should be 3 1/2 to 5 foot long and
10 to 14 inches wide. Height needs to range from 1 1/2 to 2 1/2 feet.The height of the dummy should be adjustable to accommodate different
boars. it would be beneficial to have an adjustment that can be easily accomplished by one
person. This is especially important when training younger boars and collecting mature
boars from the same dummy.The top portion of the dummy should be padded with burlap bags, foam
rubber or other material and then covered with a canvas, carpet, leather or rubber.SGI has plans for the design of the dummy and would be glad to work
with you to design a dummy that best fits your needs.
-
In some cases a portable dummy would be advantageous so that it can
be carried from pen to pen. This is helpful when training young boars or for collecting
boars in isolation.
-
In a permanent collection pen to prevent the dummy from moving, we suggest two options;
either mounting the dummy to the floor or the wall.
Purchase: SGI has portable or wall mounted
steel dummies for sale.
Area For Training:
Temperature: Comfortable for both you and the boar since it might take
some time.Lighting: Make sure there is enough light, especially on the side of
the dummy you will be collecting from.
Floor: The floor should provide excellent footing. If slick, not only
could the boar slip and cause injury to himself and you, but if his feet slide, he'll not
be able to concentrate on the job at hand. Rubber mats with holes or woven wire mats can
be used to provide good footing.
Area I - Bring Dummy to his Pen
Advantages: The dummy and yourself will be the only new items to
investigate and therefore, will possibly take less time. It is also the usual way to train
boars in isolation.
Disadvantages: If his pen is large, you'll need to block off a small
area (preferably in dry shavings or straw).
His attitude towards you will have to be somewhat amiable for you to
work close to him and not get hurt.
If his pen is in an area where there is activity, he will be more
easily distracted.
Area II - Collection Area
Advantages: Regardless of the conditions and activities going on around
the area, the collection room offers a permanent place that the trained boars will
associate with breeding. It will take less time when you're collecting many boars, be
safer and less frustrating. This room should be large enough to collect mature boars, but
not so large that it is difficult to keep the boar's attention toward the dummy. It should
be a room that offers the seclusion needed to help in keeping out any visual and audible
distractions. If possible, an area should be made accessible for untrained boars to
observe trained boars being collected.
Disadvantages: Extra expense, time and space to set up a room.
Patience: Never attempt to work with a boar when you are short of time or not in the proper
mood.
Never use negative behavior toward the animal when training - voice, hitting, etc.
Patience is probably the key factor to training and collecting boars.
Exposing Boar to Dummy or Collection Room:
Height Setting of Dummy: Prior to exposing boar to dummy - make
sure the dummy height is set so the boar can easily rest his head on it. There seems to be
a very strong correlation between a boar resting his head on an object and the action
triggering the desire to mount the object. The dummy will need to be reset to a higher,
more comfortable collection level after he is trained.
Odors: It helps to have a trained boar mount and be collected off the
dummy before exposing it to a new, untrained boar. The sheath fluid from a strange boar
can also be poured over the dummy. Boars are also intrigued by the gel produced while
ejaculating. This gel may be placed on top of the dummy and/or used to tease a boar's head
over the top of the dummy.
Position: Dummy should be placed perpendicular against the back center
of the wall. Ideally, if it is in a collection room, it will be secure, unable for a boar
to move. When collecting in a boar's pen, place the dummy at an angle so that the back of
the dummy is in a corner of the pen and where he will mount the front that points towards
the middle of the pen. Both ways, the boar can be worked with and mount from either side
or the front, but will not be allowed to circle the dummy - which can be frustrating and
time consuming.
Collecting:
Sheath Area: If possible, prior to exposing the boar to the dummy,
trim the hair around the opening of his sheath. This will prevent any hair from getting
caught in your hand while gripping the penis thus preventing you from extending the penis.
If it is not possible to trim sheath hair prior to dummy exposure, then carefully attempt
to do this once he has mounted. You may have to wait until he is trained.
Approach: Once the boar has mounted, approach him with ease. If you are
right handed, ease down on his right side. If you are left handed, ease down on his left
side. This approach enables you to use your strong hand to collect with and frees the
other hand to help tail the boar if necessary, free the sheath if it catches on the dummy,
or hold your collection container. Try not to get anxious; relax and don't worry about
getting out the collection container until the boar is extended and ready to ejaculate.
If the boar has mounted but has not started to thrust, gently
massage sheath area back and forth (head to tail) until he starts. This is especially
important for young boars who have had no exposure to breeding and are not quite sure what
happens next.
Once the boar has mounted and has started thrusting, squeeze out all of
the excess sheath fluid. This is extremely important! This fluid contains bacteria, dirt,
and potential disease problems. You don't want any of these in your collection. Any excess
that is not expelled can leak out and run down penis into the thermos or if a boar moves
closer to the dummy while you're collecting, the excess fluid can be forced out. If any
does get into the collection, you should dispose of the collection and not use it.
To maximize the strength in your arm and hand, use a palmsdown and
closed-fist approach. Using a clean, bare hand is easier in grasping penis; but once
you've gained confidence in collecting, you should use rubber gloves to provide a sterile
collection and to prevent any spreading of disease from boar to boar. When you approach
the boar's penis, remember to use your hand grip in attempting to simulate a sow's vagina
and cervix - start with back pressure and a gentle grip. The key is to grasp the curls at
the end of the penis in such a way (across the curls - like nuts and bolts) to stop them
rotating as if he was locking into cervix. When this is accomplished, he will
simultaneously thrust out to extend and you will gently pull to accommodate him in this
process. Never allow your grip to relax enough to allow him to rotate his curl once he is
extended. This means to him that he is not locked into cervix and the whole process will
have to start over again. If while attempting to firmly grip the boar's penis he begins to
back off dummy, let go. He should respond by moving back up on the dummy. If he does
dismount, he may not want to remount. He will tire more quickly if he continually mounts
and dismounts.
Once you have his penis extended and he has started to ejaculate clear,
gel-like fluids; reach for your collection container. Do not collect any of this first
clear or watery fraction of ejaculation. A creamy, white or sperm-rich fraction will
follow. Collect this portion since it contains the most concentrated amount of sperm.
Depending on how many doses you need from the boar, you can decide what portions of the
alternating phases of sperm-rich and clear fluid of the ejaculate you want to collect.
Collect all fractions subsequent to the discarded first clear fraction if you need to make
as many doses as possible. Collect just the sperm-rich fractions when you need only a few
doses. Remember that there are usually breed differences in ejaculate volume and
concentration. Yorkshires generally ejaculate a larger volume in lower concentration,
Durocs ejaculate smaller volumes and higher concentration, while Hampshire and other
breeds are usually somewhere in between.
The boar will generally go through two to three cycles during
ejaculation, taking five to fifteen minutes to complete the process. As you train the
boar, it is very important to attempt to have him go through several cycles if you want
the maximum semen produced during each collection. His penis will usually relax when he is
finished. Attempt to help him develop good habits during the collection process - bad
habits are hard to break.
Again, as emphasized earlier, use a positive approach when handling
your boar. Treat him with respect and have patience and you will both benefit from a
successful Al program.
