Electroejaculator and artificial vagina the most used to
collect bull
semen. The procedure for taking the semen sample is done with a
dummy and an artificial vagina. Semen extraction from the bull to perform
artificial inseminations is done with two known methods. One is to make the
bull believe that he will ride a cow, and the other is to stimulate it with
electrodes. Both are recommended and viable to obtain bull semen.
The genetics trade is a business that increasingly
generates more interest among producers. However, extracting semen from bulls
is a procedure that requires experts to have quality sperm, and that at the
time of being evaluated meets all the minimum requirements to be sold.
There are currently two procedures with which semen can
be collected. The first is the artificial vagina, and the second is the
electroejaculation. Both are natural, do not generate any damage to the animal
and the material collected is of high quality.
1.
Artificial Vagina
The artificial vagina has two collection methods. One is
to have a fake vagina made of leather and rubber where the outer part is
leather, and the inner part is rubber. That part is filled with warm water at
the same temperature that a real cow would be between 38 C and 40 C. Once the
vagina is ready, it approaches the bull that rides. A professional diverts the
penis into the artificial vagina so that the animal ejaculates inside it.
The other way is to use a dummy inside which the
artificial vagina goes. The device is made of a rigid metal housing, where a
person sits inside it to hold the artificial vagina. The dummy is approached by
the bull to mount it and once the penis is removed; the assistant simply
directs the artificial vagina to the limb so that the male ejaculates. The
ejaculate of the bull will have a higher sperm concentration with a low
percentage of liquids from the accessory glands. It is an ideal sample to work
in freezing the bull semen.
2.
Electroejaculation
It is a part physiological procedure to collect semen. It
consists of using electrical stimuli similar to those sent by the brain to the
sexual, accessory glands and the penis, which results in an erection and
ejaculation. The electroejaculation is used using a device. It is introduced
rectally from the male and sends light and oscillating electric shocks to the
reproductive system of the bull to obtain semen.
Semen collection should be done in a collection room. The
collection can be made with artificial vagina (VA) or manually, either with a
gloved hand (the so-called Japanese method) or by entering the penis in a
disposable rubber cylinder (IMV, France). In the case of semen collection for
field diagnosis, the most indicated (and probably the only form of a group) is
to use a sow in heat, age and size fit body for the bull. The semen is
collected in a plastic bag mounted in a thermos or a wide-mouth insulating
container.
