The boars are rushed into the sperm collection room, where they are allowed to sniff and arch the swine pedestal. The staff strokes the boar's genitals and abdomen to stimulate their sexual desire. When the boar's libido reaches a high level, it will climb. On the sow's table, and stick out penis glans back and forth. At this time, if the sperm extractor uses the right hand to collect sperm, he must lie on the left side of the boar. The right hand grasps the spiral head of the boar's penis and pulls the penis out of the way. He then shrinks slightly until he and the boar penis. At the same time, exercise, the left hand to pick the fine cup; if you use the left hand to collect fines, you have to lie on the right side of the boar, left hand to grasp the penis, the right hand to pick the fine cup. In this way, the picking personnel face the boar's head, mainly to be able to notice changes in the boar, prevent boars from jumping when the boar suddenly jumps, and at the same time, when the picking staff can issue a sow-like estrus. When the sound of the "click" sounds close to the sow, it will have a great effect on stimulating the libido of the boar, which will help the boar ejaculate. When holding the spiral part of the penis, the remaining three fingers fit together and, like cow milk, rhythmically bouncing along with the penis movement, giving the boar stimulation. When the sperm is collected, the hand holding the penis usually wears double-layered gloves, preferably polyethylene. The strength of the penis is too large or too small to prevent it from falling and catching. Too small, the penis is easy to fall off, less than fine: too much force, one is easy to damage the penis, and second, it is difficult for the boar to shoot semen. Once the boar starts ejaculation, the hand should immediately stop the kneading and just hold the penis. After the ejaculation, it should be pinched immediately to stimulate it to ejaculate again.
Before boar ejaculation, boars are stimulated to produce libido. When boars ejaculate, they should stop stimulating the penis of the boar. Immediately after ejaculation, stimulate the boar to ejaculate again to obtain the maximum amount of semen.
In order to obtain less contaminated semen, the residual urine in the foreskin of the boar should be squeezed out before the sperm is collected, and the foreskin and the exposed glans should be wiped with toilet paper. When ejaculation is started, the relatively dilute spermatozoa that have been shot before and the dirt are wiped off. Things.
In order to keep the spermatozoa high in vigor, the harvesting cup should be kept at a suitable temperature during the sperm collection process so as not to cause a temperature hit on the sperm, resulting in decreased sperm motility.
