Graniteville, Vt. (AP)- (Excerpt) Robots have taken up residence at some small and medium sized dairy
farms across the country, providing reliable and more efficient labor and
helping businesses remain viable.
All praise to technology and computer geeks. I take back every bad thing I’ve ever said
about you. You’ve transformed the life
of the dairy farmer, the most oppressed, confined, and tethered of all farmers
in history bar none. This is the best
thing since sliced bread. Who am I
kidding, its way better than sliced bread.
It’s freedom. Pure unadulterated
freedom. God bless you programmers
locked in rooms unable to speak intelligibly because of the code running
through your heads. You wonderful geeks
may not even know what you’ve done.
My family and their predecessors milked Jersey cows on a
small farm between Danvers and Mackinaw for God knows how long, probably 100
years. They delivered raw whole milk,
coffee cream, and whipping cream to the people who lived in town until
pasteurization requirements put such small dairies out of business. They made their own butter and fed the skim
milk to the cats. In 1941 they invested
in the future as they saw it and built a modern state of the art dairy barn and
milk house that complied with looming health laws. They closed the Danvers delivery operation and
shipped Grade A milk to Prairie Farms Dairy until my Mom and Dad retired and
sold the cows in 1979. Let’s just take a
stab at quantifying how much work that represents.
If the Sloanes or those before them began milking cows in
1879 (that’s possible) and the McClures took up that task after them not
stopping until 1979, they milked cows for 36,500 days not screwing around with
leap years and the like. Dairy farmers milk
cows twice a day rain or shine, sickness or health, weather so bad you can
hardly get to the barn. That’s 73,000
milkings. Spouses and children die, wars
break out, calamities occur, tornadoes threaten, ice storms force you to chip
open the milk house door, but twice a day you quietly go to the dairy barn,
open the door, feed the cows, and relieve them of their milk. Their milk is both your food and your
livelihood. Selling milk is a steady
year round source of revenue. Your labor
is rewarded, but oh my how it affects your life. Morning and night, morning and night, milking
cows with no end in sight. Committing
yourself to dairy farming is like a sentencing yourself to a lifetime of hard
labor. Until now, the dawning of a new
age, when cows milk themselves with the aid of robots.
In the past if you milked cows you could of course go
anywhere you wanted. It’s still a free
country. You can go anywhere, after you
milk the cows in the morning that is, and as long as you can get home by 4:30
to milk them again.
Want to look at that more closely? You get up, often in the dark, put on your
chore clothes and make your way to the kitchen.
Mom has made coffee. You may have
some, with conversation, or you may just sit there under the dim kitchen light
and listen to AM radio; ads, jingles (still in my head), and bouncy
announcers. You go to the basement and
put on your coveralls and boots, hat and gloves. Outside you make your way to the barn. In winter the cows are kept inside, two rows of twelve facing outside windows. When you open the door an entire row of
twelve cows facing you, twenty four big black eyes, look at your
expectantly. You are their keeper. You know them each by name. The first thing you do is feed them.
In summer when the cows are on night pasture the cows are
outside the barn, waiting at the door.
You put scoops of feed in the manger in front of each cow’s place,
knowing which stall each cow goes to, adjusting the amount of feed, more for
the heavy milkers, less for the lightweights, only half for cows gone dry, a
month or so away from delivering their next calf. You slide the barn door open
a foot or so. The cows look up at you expectantly;
docile, patient, and hungry. You slide
the doors completely open and they file in, step across the gutter, put their
necks through the steel stanchions, always the same stall, and begin to
eat. When they are all in you close the
stanchions, locking them in, turn on the pump (an electric motor creating a
vacuum line up and down the rows of cows), bring in the milkers, pails, and
wash water and begin.
24 cows, 12 petcocks providing vacuum to three Surge milking
machines, which are suspended under the cow’s udder on straps called surcingles
over the cows back by their hip bones. Eight
changes at the most if all 24 cows are being milked, five minutes or so per
change, forty minutes for the milking itself.
Chores, the generic word for our morning and evening tending to the
cows, took longer. Hour and fifteen
minutes. Less if you hurried. Twice a day, every day, for what seemed like
the rest of your life. You could do it
yourself if you had to, but it was best done with two.
The invention that was most revolutionary for dairy farmers,
after electricity, was the milking machine.
Prior to that you sat beside every cow and milked them individually by
hand. I cannot imagine. From time to time a cow with an injury or
mastitis required one or more quarters be milked by hand and I would do it,
unless Dad beat me to it. Hand milking connects
you with the cow in an almost meditative way. It not only takes longer it allows
you to do nothing else. Two teats at a
time, alternate squeezes until dry, repeat.
Milking machines introduced speed and freedom to the dairy barn. While the machine manipulates the cow’s teats
four at a time and extracts the milk, rubber sleeves automatically inflating
and collapsing in stainless steel cups, you could carry milk to the milk house,
wash the teats of the next cows to be milked, feed hay, any number of things. Besides your mind going far away during hand
milking your hands tire.
“Makes your grip strong,” my Dad would say. Dad was a positive guy.
Positivity helped dairy farmers survive I
think.
The dairy invention that revolutionized milking in my lifetime
was the barn cleaner. The Badger Company
out of Wisconsin made them popular.
Investing in a barn cleaner relieved the dairy farmer from a very important
but unpleasant task. Shoveling shit.
To accommodate bigger herds dairy technology went to barns with
milking parlors and lounging sheds sometime in the sixties and the cows shit in
large areas that could be cleaned with tractors and loaders. Our barn with stanchions became the cow’s
winter home. A good dairy cow eats
alfalfa hay and ground feed voraciously, drinks a lot of water, stays skinny,
and turns all her energy into milk production and producing calves. Because of all that, dairy cows produce
manure in prodigious amounts. That
manure, in a smaller confined stanchion barn, must be removed daily. Add that to your winter chores. Here’s how
that goes.
Empty two fifty foot concrete gutters full of cow manure by
shoveling one scoop of shit at a time into a wheelbarrow. When full, brimming, wheel the barrow up a
ramp out a side door, across a wooden runway, dump it into the waiting manure
spreader, bring it back on the same path, and prepare to refill. Repeat twelve times. On a cold and windy winter day when the
manure was steaming my brother Darwin, just a kid, was emptying a loaded
wheelbarrow into the spreader and a gust of wind blew him headfirst into the spreader. He got out, but not before cow shit filled
his ears and nose. All kids, they say,
need to learn how and when to keep their mouth shut. My older brother learned the hard way. Darwin was never fond of milking cows.
When the gutters were empty of manure we spread crushed
limestone in the gutter, and when the spreader was full (every third day or so)
hooked the tractor onto the manure spreader, affectionately called the terd
hearse, and drove it to the assigned field where we engaged the chain drive which
fed the manure to the back beaters and flung shit high in the air. We drove over the field till empty, watching
for wind and changing direction cautiously, then drove back and put the manure spreader
back into position. Elapsed time from
the start of shoveling to the end? That easily
averaged an hour a day from October till April.
Sundays too.
A barn cleaner like the one Badger sold had a powerful
electric motor at the end of an elevated steel chute that dragged a continuous heavy
linked chain with paddles through the gutters, automatically pushing the cow
manure up the chute where it emptied into the manure spreader. Voila.
A load of cow shit ready to spread untouched by human hands. All that was required of the dairy farmer was
to throw a lever on an electrical box.
The first time we saw it work we had huge smiles on our faces. Technology. We loved it.
Really, who cared how much it cost?
There was symmetry to the kind of farming we did on that
small farm. Dad rotated crops on all the
tillable acres: soybeans, corn, oats, and alfalfa. We had permanent pasture with timber and a
creek on land that otherwise couldn’t be farmed. We scooped forty scoops of oats and sixty
scoops of ear corn in a little box wagon we hauled to town behind a tractor each
week to the feed mill at the elevator.
They added soybean meal, salt, and molasses and ground it while we
waited. The seal on the molasses valve
leaked and I always got a thick finger full of molasses off it. We brought the wagon home full of feed and
scooped it back into the feed room in the barn.
Scooped it twice-first as whole grain next as feed.
We made two thousand bales or so of alfalfa hay each year
and threw small bales down from the mow to feed the cows twice each day they
were not on pasture. In addition we made oat straw for bedding. The grain and hay the cows ate and of course
the pasture they grazed all came from the land around us. We drank raw milk from the cows and ate the
cows as well, butchering them ourselves when I was young and later at the slaughter
house in town. We stored the meat at the
locker plant, a big communal freezer in Danvers, until we got our own deep freeze
at the house. We fertilized our fields with manure from the cows which in turn
helped grow the crops we fed the cows. The cows not only made us money but fed
us too. Same with the chickens. Milk, eggs, meat, and the garden dominated
our diet. Mom canned vegetables; sweet
corn, green beans, pickles, pickled beets, and on and on. We were organic and didn’t know it. My Dad, being a modern farmer, used
commercial fertilizer and other chemicals as did neighboring farmers in the
grain fields when they became available, but he never stopped rotating crops or
spreading manure. It’s hard to find that
kind of farm now. But I have a feeling,
and a hope, that technology may make it possible for dairy to achieve small
scale viability through new efficiencies like these robotic milkers.
Modern farmers are using them to save labor costs, something
we never incurred on our farm, because the family did all the milking. We were a farm family. My brothers and I helped my Dad, but no one
helped as much as my Mom. She was in the
barn with the rest of us, and cooked all the meals and did the dishes besides. I don’t think farmers valued their labor then
in terms of dollars. Putting long hours
in on the farm was simply what farmers did.
The temptation, perhaps economic necessity, of working in town for wages
to supplement farm income probably killed off small dairy farms. Consider the winter work schedule circa 1960
for our small scale dairy operation like ours in Danvers.
6:30-8:00 a.m. Morning milking, feed the calves
8:00-9:00 Breakfast
9:00-10:30 Wash the milkers, clean the barn, spread manure
10:30-noon Other farm work
NOON Dinner (followed by my Dad’s big nap)
1:30-4:30 p.m. Other farm tasks
4:30-6:00 Evening milking, feed the calves
6:00-6:30 Wash the milkers
6:30 p.m. Supper
6:30-bedtime Leisure
Take that day and repeat it for the entire number of days
you own a herd of dairy cows. That was
your life as a dairy farmer. You could
squeeze in a day off the farm from time to time, but only between 8:00 a.m. and
4:30 p.m. and certainly not two days in a row, lest you fall behind. In addition to the milking you had the grain
farming; planting, harvesting, and cultivation, plus making hay, repairing
equipment, caring for the pasture, cutting thistles, making fence, shelling
corn, countless other tasks that farmers simply did. Take away the every day,
twice a day task of milking however, and you might be able to take a job that actually
paid you money directly for hours worked.
As tractors and implements improved and got larger, enabling farmers to
plant and care for more grain acreage, selling dairy cows became easier not
only because the milk check became smaller as a proportion of farm income, but
because by doing so you could escape a grueling every day schedule of hard
work. You could begin to imagine such a
thing as “vacation,” something we never experienced as a family. I take that back.
When I was eight we drove to Ft. Leonard Wood Kentucky to
watch my brother graduate from Army basic training. We were gone three days and two nights and
stayed in motels for the first time ever.
That was the extent of travel with my parents as a kid. In our absence our neighbor Henry milked the
cows.
Modern dairy farmers in the United States have been using
migrant labor to milk cows, and it has been in short supply. In the Netherlands, where labor is more
generously rewarded, more than half the dairies now use robotic milkers. Jesse and Jennifer Lambert of Graniteville
Vermont just took out a seven year $380,000 loan to install two robots and
retrofit a barn at their organic dairy farm.
They were looking for a more consistent way to milk their cows, spend
more time with their newborn son, and at the same time save money. They are saving $60,000 a year in labor costs
that would have gone to a full time and part time employee, and are producing
20% more milk.
“No one wants to milk cows,” Jennifer Lambert said. “Especially on the weekend.”
She also thinks the robots lead to more relaxed cows. When a cow wants to be milked, it simply
steps up into a stall, grain is dumped in front of it, and an arm reaches under
its body to wash the teats. Next a laser
scans the cow’s body, and the arm attaches a cup to each of the four teats,
milking them individually. In addition,
the technology collects and stores data about each cow’s production, body
temperature, weight, and number of visits to the milking system and sends all
that data to the farmer’s computer.
Wow. You could sit in
the barn on a lawn chair and read your smart phone or kindle while all that was
going on. Or stay in the house and read
about it later on your computer.
I worked on a dairy farm near Aberdeen, Scotland in the
winter of 1975 that milked 260 cows aided by a computerized system. As groups of twenty cows came in the milking
parlor we entered each cow’s number, printed on large ear tags, into a computer. That number generated a portion of feed that
was consistent with where they were in their cycle, cutting back as their milk
production waned, doing what Dad did with a feed scoop and the knowledge of
each cow in the barn. It was nothing
more a feed and data system. But I never
imagined a machine could milk a cow. Why
not I wonder? Now 40 years later it’s a
reality.
