This is my lab set-up.
During breeding week, it lives on my dining room table. Most of it is pretty inexpensive, and there isn't a computerized semen analyzer anywhere in sight.
But before I put several hundred dollars' worth of semen into a sowโand bet a litter on itโit allows me to answer one pretty important question:
๐๐ฐ๐ฆ๐ด ๐ต๐ฉ๐ช๐ด ๐ด๐ฆ๐ฎ๐ฆ๐ฏ ๐ญ๐ฐ๐ฐ๐ฌ ๐ญ๐ช๐ฌ๐ฆ ๐ด๐ฐ๐ฎ๐ฆ๐ต๐ฉ๐ช๐ฏ๐จ ๐ ๐ธ๐ข๐ฏ๐ต ๐ต๐ฐ ๐ฃ๐ณ๐ฆ๐ฆ๐ฅ ๐ธ๐ช๐ต๐ฉ?
For a few hundred dollars, you can build this setup at home.
๐ช๐๐๐ง ๐ ๐จ๐ฆ๐:
โข Basic binocular microscope โ mine came from Amazon (SWIFT SW380B)
โข Microscope slides
โข Disposable plastic pipettes
โข Clean boar semen bottles and lids
โข Insulated tumbler
โข Digital meat thermometer
โข Two reusable ice packs
You can piece this together online, and I highly recommend ๐ฅ๐ฒ๐ฝ๐ฟ๐ผ๐ฑ๐๐ฐ๐๐ถ๐ผ๐ป ๐ฃ๐ฟ๐ผ๐๐ถ๐๐ถ๐ผ๐ป๐ ๐ฎ๐ ๐ฎ ๐ด๐ฟ๐ฒ๐ฎ๐ ๐๐ผ๐๐ฟ๐ฐ๐ฒ ๐ณ๐ผ๐ฟ ๐ฒ๐๐๐ฒ๐ป๐๐ถ๐ฎ๐น๐น๐ ๐ฎ๐น๐น ๐ผ๐ณ ๐๐ผ๐๐ฟ ๐๐๐ถ๐ป๐ฒ ๐ฏ๐ฟ๐ฒ๐ฒ๐ฑ๐ถ๐ป๐ด ๐๐๐ฝ๐ฝ๐น๐ถ๐ฒ๐.

Gently rotate the semen bottle until any settling or clumping is no longer present, then draw a small amountโusually a couple mL or soโinto a disposable pipette.

This sounds silly to emphasize, but it took me a minute to figure out.
If it's sitting in the stem, put your finger securely over the tip and gently swing the pipette. Allow gravity and a little centrifugal motion to pull the semen into the bulb.
That's important because the ๐๐ฒ๐บ๐ฒ๐ป-๐ฐ๐ผ๐ป๐๐ฎ๐ถ๐ป๐ถ๐ป๐ด ๐ฏ๐๐น๐ฏ is what we're going to submerge in the warming bath.
๐ฎ. ๐ช๐๐ฅ๐ ๐ง๐๐ ๐ฆ๐๐ ๐ฃ๐๐
Fill an insulated tumbler with warm water and use a digital meat thermometer to bring it to approximately ๐ญ๐ฌ๐ฌยฐ๐ (๐ฏ๐ณโ๐ฏ๐ดยฐ๐).
Submerge the bulb of the pipette, making sure the semen itself is below the waterline, and put the lid on.
I usually feed the pipette through the drinking opening in the lid and push the cover tight against it. That keeps the bulb submerged instead of allowing it to float back up.

๐ถ๐บ๐ฎ๐๐ฒ๐น๐ ๐ญ๐ฑ ๐บ๐ถ๐ป๐๐๐ฒ๐ ๐ฎ๐ฟ๐ผ๐๐ป๐ฑ ๐ญ๐ฌ๐ฌยฐ๐, but I follow the stud's recommendation for their product.
Good studs appreciate the feedback and are usually excellent resources if something doesn't look right. Their goal is the same as ours:

I don't want to warm a semen sample and immediately put it onto cold glass.
My sophisticated solution: ๐๐๐ผ ๐ฟ๐ผ๐ผ๐บ-๐๐ฒ๐บ๐ฝ๐ฒ๐ฟ๐ฎ๐๐๐ฟ๐ฒ ๐ฟ๐ฒ๐๐๐ฎ๐ฏ๐น๐ฒ ๐ถ๐ฐ๐ฒ ๐ฝ๐ฎ๐ฐ๐ธ๐ ๐ฎ๐ป๐ฑ ๐ฎ ๐บ๐ถ๐ฐ๐ฟ๐ผ๐๐ฎ๐๐ฒ.

Sandwich your slides between the warmed packs while you wait for your semen sample to warm.

After warming, get the semen back toward the pipette tip. Again, a finger securely over the end and a few gentle swings can help move it.
You'll probably encounter some air bubbles. Work through those until you're getting good semen drops, then place ๐ผ๐ป๐ฒ ๐๐ผ ๐๐๐ผ ๐ฑ๐ฟ๐ผ๐ฝ๐ ๐ผ๐ป ๐๐ผ๐๐ฟ ๐๐ฎ๐ฟ๐บ๐ฒ๐ฑ ๐๐น๐ถ๐ฑ๐ฒ.
Now, take a look.

This isn't a computerized semen analysis, and I'm not pretending to generate a laboratory-grade motility percentage.
For an at-home field check, I'm asking:

This isn't a tutorial on how to use your particular microscope. Ask your veterinarian friend, vet-tech friend, high-school biology teacher or community-college microbiology professor.
And if you don't have any of those kinds of people in your life, start building your community.
Bring baked goods. Bring donuts. Whatever it takes to establish a little goodwill. ๐๐ผ๐ผ๐ฑ ๐ถ๐ ๐ฎ ๐ฝ๐ฟ๐ฒ๐๐๐ ๐๐ป๐ถ๐๐ฒ๐ฟ๐๐ฎ๐น ๐น๐ฎ๐ป๐ด๐๐ฎ๐ด๐ฒ ๐ณ๐ผ๐ฟ ๐ด๐ฒ๐ป๐ฒ๐ฟ๐ฎ๐๐ถ๐ป๐ด ๐ธ๐ถ๐ป๐ฑ๐ป๐ฒ๐๐.
You don't have to be a veterinarian or reproductive physiologist to learn to focus a microscope and recognize whether s***m are moving progressively.

Some semen packaging is easily sampled. Some isn't.
I keep clean, purpose-made boar semen bottles and fresh lids on hand. If necessary, I can transfer a dose into a clean bottle so I can sample it and know what I'm working with.

Breeding protocols are breeding protocols. I'm no genius at knowing the nuances of ๐๐ผ๐๐ฟ sows (nor do I aspire to be).
There is no replacement for ๐ฌ๐ข๐จ ๐ธ๐ป๐ผ๐๐ถ๐ป๐ด ๐๐ผ๐๐ฟ ๐๐ผ๐๐ to gauge when to breed. Their reproductive history, heat detection, timing, insemination technique, fertility, semen storage and handling all matter. And good-looking semen certainly doesn't guarantee pigs.
This little lab simply helps answer one more question:
๐๐ผ๐ฒ๐ ๐๐ต๐ฒ ๐๐ฒ๐บ๐ฒ๐ป ๐'๐บ ๐ฎ๐ฏ๐ผ๐๐ ๐๐ผ ๐๐๐ฒ ๐น๐ผ๐ผ๐ธ ๐น๐ถ๐ธ๐ฒ ๐๐ฒ๐บ๐ฒ๐ป ๐ ๐๐ฎ๐ป๐ ๐๐ผ ๐ฏ๐ฒ๐ ๐๐ต๐ถ๐ ๐น๐ถ๐๐๐ฒ๐ฟ ๐ผ๐ป?
If it doesn't, knowing that ๐ฃ๐ฆ๐ง๐ฐ๐ณ๐ฆ ๐บ๐ฐ๐ถ ๐ฃ๐ณ๐ฆ๐ฆ๐ฅ gives you options: recheck it, check another dose, call the stud, choose another boar, or use it and follow with something stronger.
The risk isn't simply using a questionable sample.

People ask what I'm breeding a particular sow to, and my answer is often:

Of course I make mating plansโbut the first objective is still ๐ฃ๐๐๐ฆ.
At today's semen prices, and with how much the age and timing of a litter can affect its value, a few hundred dollars invested in a miniature semen lab is cheap insurance.
It won't tell you when to breed. It won't guarantee pigs.
