It's that time of year ... time for cough drops

I paid attention during the job requiring basic knowledge so said product could be shipped across state lines. Do you really think farmers line up 100 boars and 100 sows, then say, "Hey, go to it?"

Just to prove it, I found this helpful article. Just substitute the phrase "Bubbler's tongue" or "Bubbler's lips" in place of "hand" or "fingers":

Collecting semen
Use a shady, draught-free area when collecting semen since exposure to ultra violet light, sudden temperature changes and water contamination, lower the spermatozoas viability.

When the boar is mounted on the dummy grasp the spiral end of his penis with the hand (gloved or bare, it must be clean, dry and warm). Allow the boar to thrust through the clenched hand a few times before applying pressure. Hand pressure on the spiral part of the penis, imitates that of the oestrus sows cervix, stimulating ejaculation. With experience, it becomes obvious that some boars prefer more pressure than others. The long hairs around the boars prepuce should be clipped to minimise injury.

When the penis is 'locked' in the hand and the boar relaxes, a four-phase ejaculation follows in a few seconds, taking 5 to 10 minutes to complete. The first phase, called the pre-sperm fraction, has clear seminal fluid, some gel, dead sperm cells and is heavily contaminated with bacteria. It should not be collected.

The next phase is the sperm-rich fraction, easily recognised by its creamy- white colour. Although only 50 ml in volume, it contains the greatest density of spermatozoa. Because spermatozoa are very sensitive to rapid temperature change, a warm, dry, insulated collecting flask is required to safeguard semen fertility. The third fraction, greyish because of lower density of spermatozoa, accounts for about 80 ml of the collection. Fractions two and three only are collected when semen is to be diluted for storage over a few days.

The fourth phase or post-sperm fraction provides the large semen volume peculiar to pigs. Up to 250 ml of clear seminal plasma free of spermatozoa, plus gel is secreted from the accessory glands. The gel portion apparently has no physiological significance. It is separated from the collection by several layers of gauze or a similar filter fastened over the collection flask. Filtering particles of gel from the semen prevents catheter blockage during insemination. Hair, skin or dust particles from the boar or dummy must also be excluded from the flask during collection.

Large amounts of gel signal the end of ejaculation. When it is clear the boars erection is fading, a second ejaculation can be stimulated with brief, firm, pulsating hand pressure applied to his penis.
