Let Sleeping Pigs

Sep

Let sleeping pigs….
img_8534
….make friends with the chickens….
img_8539
….show off their bums….
img_8538
….and look ridiculously cute because when the pigs wake up, they root around the yard, turn over every stone (literally, like in a rocked wall garden), and generally tear everything up.

So. An effort was made to block their escape path, which is the new larger pipe in the culvert.
img_8542
(A very dry creek, by the way.) Of course, they employed their young goat friend, Hickory, to show them how to push up the wire to get back into the pipe.
img_8543
And through!
img_8548
And they’re out again, to the other side!
img_8558
There’s a pool of water in the creek on this side.
img_8560
To be clear, it’s not as if they don’t have water. I’ve deliberately allowed them to create a puddle in the barn yard and I run water into it from the hose at the barn twice a day to give them a bathing puddle. Plus they have water pans and buckets of water around the barn yard. But, they want to be here.
img_8557
And I have to admit, it’s really hard to deny them because they’re so ridiculously cute.

I also have to admit that I really like these pigs. These are the first pigs I’ve ever had that I genuinely liked and enjoyed and have let free range around the barn. They’ve become very pet-like, and these are the first pigs I can foresee being truly difficult to see go to the butcher.

We never should’ve become friends.

Why Milking Machines Suck, and Should

Sep
16

My friend Jerry dropped by the farm one day and I showed him my new milking machines. He’s interested in mechanical things, so I showed him how they all go together–the inflations and lines and so on, describing how they’re attached to the cow or goat, and bringing out my old Surge milking machine also to compare the machines. I explained that the Surge was the first milking machine that brought it all together in terms of what makes a functional milking machine that is healthy for the cow by imitating the sucking action of a calf, and that it was the basis for all modern milkers today. He looked at all the equipment and said, “So what makes it work?” I said, “There’s a vacuum pump in the barn. The machines are connected to the vacuum pump.” He said, “But what makes it work?” I said, “You plug it in! The vacuum pump runs on electricity. There’s electric in the barn.” (Because, DUH, Jerry!) He said, “BUT WHAT MAKES IT WORK?”

In that (blonde) moment, I realized that, while I demonstrate and teach about milking and milking equipment during workshops at the farm nearly every weekend, I still sometimes can lose the details in the whole of the end result. There are many parts and pieces to the puzzle that makes up a complete milking machine. Basically, it takes a village–all those parts and pieces are necessary to make the whole. But, there is one part that came to the party late. It revolutionized milking machinery and, as a crucial component of the Surge milker, became the heartbeat of every other milking machine today–so omnipresent in modern milking that I can almost forget how critical it is when I’m looking at the complete puzzle put neatly together.

Jerry, being a very inquisitively- and mechanically-minded person, was looking for that one specific piece that would make the whole make sense.

“Oh,” I said, “You mean the pulsator! That’s what makes it work.”

At which point Jerry slapped me and went home. (JUST KIDDING.)

The original milking machine. (Patent: Mother Nature.)
IMG_7877
A baby can’t swallow in one long, continuous drink. It sucks and swallows, in a regular and repeating rhythm. Suck, release, suck release. When sucking, their mouth is closed over the top of the teat, pulling the milk from the teat into their mouths. Between sucks, they release the pressure, allowing more milk to fall naturally from the udder into the teat. The baby does this over and over, sucking and releasing, until they’re satisfied.

Hand-milking. (Patent: Ancient civilization.)
IMG_8436
In hand milking, we recreate the on and off action of the calf by closing off the top of the teat then pushing down to move the milk out the tiny pin hole at the bottom. With the top of the teat pressed shut, the milk has nowhere to go but down and out. Then you release the pressure on the top of the teat, allowing more milk to fall naturally from the udder into the teat. Then close off the top of the teat again and push the milk down and out again. And repeat again. And again, just like a baby.

Modern milking machines use inflations–rather than a baby’s mouth or a human’s hands–to cover the teat. The inflation is made up of an inner liner of flexible material housed inside a protective outer shell.
IMG_8448
The inflations (two for goats, four for cows) are connected to the machine with two lines per inflation–a milk line, which transports the milk cleanly and efficiently to the milking machine bucket, and a vacuum line, which supplies the suction from the vacuum pump.
IMG_8465
Connected between the vacuum pump and the inflation vacuum lines is one very important element, and that is the pulsator, which delivers the vacuum suction on a regular interval basis, known as a pulsation rate.
diagram_edited-1
Taking this back to simpler terms, this means the suck and release of a calf or the squeeze and release of a human hand. The pulsator breaks up the vacuum, creating a pull and let go pattern instead of a non-stop pull.
IMG_8437
This makes a machine that treats the animal in a manner that imitates nature, which previous incarnations of milking machinery did not. Early vacuum pump-based milking machine attempts relied on simple straight suction at a constant level. Imagine how damaging that was to a cow’s udder. The pulsator was first employed in milking machines in the late 19th century, but was not in widespread use until over half a century later when the creators of the Surge brought the pulsator together with a fully functional overall design.

Surge, with pulsator:
IMG_8457
And over half a century again since then, milking machines today are still based on that breakthrough format. While materials, designs, and efficiency have continued to advance, the pulsator is still….

….what makes it work.

In this video, you can see the action of the pulsator applying the suck and release to the inner lining of the inflations, and thus to the teats, creating nature-inspired machine milking. I’m using my goat milker from Hamby Dairy Supply to demonstrate because it has a clear outer shell which allows you to see the magic happening inside.

    July 12, 2016 - The Easy Way to Milk Goats

    In the days following the recent massive flooding in West Virginia, I was milking goats the hard way, by hand with a flashlight in the barn. To call that process challenging would be tantamount to calling the rain we had here on June 22 a light sprinkle. Boy, did I ever miss my goat bucket milker! But, without power (the generator was being used to run fridges and freezers at the house) … Continued…

    June 7, 2016 - Calf Update

    I haven’t updated about Dumplin because….there’s been nothing to update about Dumplin. She was with the bull last summer during the same period of time as Glory Bee and Moon Pie, who both delivered calves in April. Obviously, the bull wasn’t shooting blanks and he hit them up right off the bat. He was here for three months, so the mystery continued–Dumplin could still deliver in June.

    But, the mystery is now solved! … Continued…

    Got cows?

    Then you’ve got milk! And the baby doesn’t need all of it. You could use the original cow milking system….you know, your hands.

    After all, hand-milking is a low-tech operation. You need hands and a bucket. Clean up is as easy as putting the milk bucket in the dishwasher. But milking the cow…. … Continued…

    May 23, 2016 - The Mother Duck Rides Again

    Remember the white Pekin mama who lost one baby then trampled another? (See here if you missed that one.)

    I took the four babies she had left and put them in a pen for safekeeping, along with seven Blue Swedish ducklings I’d gotten from a hatchery.

    She wouldn’t leave them. She was dedicated, committed, obsessed with … Continued…

    May 17, 2016 - The Little White Duck That Could

    I love duck eggs. They make a great fried egg, and they’re awesome for baking. Duck eggs are huge, super jumbo size. I buy special dinosaur egg cartons for them, and I sell them when I have enough. I don’t always have enough because they hide them. The ducks are free-ranging, so they make their nests here and there and in secret spots. It’s like an Easter egg hunt … Continued…

The Slanted Little House

"It was a cold wintry day when I brought my children to live in rural West Virginia. The farmhouse was one hundred years old, there was already snow on the ground, and the heat was sparse-—as was the insulation. The floors weren’t even, either. My then-twelve-year-old son walked in the door and said, “You’ve brought us to this slanted little house to die." Keep reading our story....
