Richardson, a former schoolteacher, has learned a lot about farming from Lowell Heim and the other dairymen with whom he works.

Three years ago, Robert Richardson gave up his career as a
teacher, moved to the country… and stepped right into a
unique $15- to $35-per-day (plus meals) job that few
back-to-the-landers–it seems–have heard of.
Here, Bob tells us all about his novel–and
profitable–line of work.

If you already live in the country and need a good, steady
source of extra income–or if you’ve made up your mind
to move to a rural area but you don’t know how you’ll earn
a living once you get there–I know at least one line
of employment that you should check out. It’ll let you [1]
meet people on equal terms, [2] have the sunniest hours of
the day off, and [3] learn a lot about dairy animals in a
short time.

Why not, in other words, think about becoming a milk
tester–or “field(wo)man”–for the Dairy Herd
Improvement Association?

The DHIA fieldman helps dairy farmers keep accurate milk
production records on each of the animals (usually cows,
but sometimes goats) in their herds. More specifically,
this is how you’ll spend your time if you do land a job as
a fieldman:

In the late afternoon, you’ll drive out to a farm
and–unless your host prefers to eat after milking,
which is sometimes the case–sit down with the dairy
farmer’s family and eat supper. Once this formality has
been satisfactorily taken care of, you’ll accompany the
dairyman, his wife, and their children (if they are to
help) out to the barn for the evening milking.

Then, as each cow is milked, you’ll weigh her output and
record the weight beside the animal’s name or number on the
“barnsheet” you’ve brought along for this purpose. You’ll
also collect and tag a small sample of each cow’s milk for
a butterfat analysis that will be conducted later.

The next morning, you’ll return to the same farm
and–except for eating breakfast this time instead of
supper–repeat the procedure. (A few years ago, it was
common practice for milk testers to stay overnight on the
farms they visited. One woman who works in our association
still does this, since most of the farms she covers are
located some distance from her home . . . but her situation
is now an exception to the rule.)

After you’ve finished breakfast and the cows have been
milked, you’ll return to the DHIA laboratory you work out
of and drop off the milk samples and barnsheets. And that’s
it . . . until about six hours later, when–in the
late afternoon–you’ll visit another farm.

How to Qualify

If all this sounds pleasant and easy, it is. And you don’t
need prior dairy experience to land one of these jobs! My
“qualifications” before becoming a fieldman were threefold:
[1] years before, as a youngster, I had milked a cow that
my dad kept, [2] I had once raised a dairy heifer as a 4-H
project, and [3] I answered the ad. And, except for the
fact that they gave me enough confidence to apply for the
job, the first two points actually were irrelevant.

Believe me, this job’s been done–and done
well–by many people who, until they became fieldmen,
knew nothing about dairy work. One of my co-workers–a
man who’s been testing milk for the last 14 of his 74
years–came to this occupation straight from a long
stint with a dog track in Florida. Before that, he’d been a
chauffeur in Chicago.

So don’t let the fact that you’ve never seen the inside of
a barn before (if that’s the case) intimidate you. If you
can pour milk out of a cup, you can become a DHIA milk

Why Test Milk?

Perhaps you’re wondering
(and I don’t blame you) just why anyone should be paid to
go around and collect these samples of milk. The answer is
simple. All cows eat a lot, but not all cows give a lot of
milk. And a dairy farmer–if he’s to make well-founded
decisions about the feeding and breeding of his
herd–needs to know exactly which cows are the “big
producers”. (Finding heavy milkers isn’t as easy as you
might think, because you can’t see their milk as
it flows from the teat cups of a modern automatic milker
through a pipeline to the milkhouse cooling tank. All you
know for sure is that the cow stood there with the milkers
on her for a certain length of time . . . which doesn’t
necessarily say anything about how much milk the old gal

By having his herd tested, then, a dairy farmer is able to
learn precisely how much milk each of his animals produces
from month to month and how much butterfat that flow
contains. (The higher the fat content, the more the
dairyman is paidper pound–for the milk.) This
information–in turn–helps the farmer to decide
such things as how much feed a given cow should receive,
and to what bull she should be bred. (The finer points of
feeding and breeding are, of course, quite complicated. In
general, though, a heavy milker usually needs and gets a
heavy ration of grain . . . while an animal that produces a
heavy flow of milk with a consistently low butterfat
content will probably be bred to a bull that has a record
of improving butterfat production in his offspring.)

As you can see, the DHIA testing program gives dairymen a
good deal of valuable information that can help them make
more money. Your job is to pick up a few bucks for yourself
by helping to provide that information.

Where to Apply

The DHIA testing program is sponsored by the Department of
Agriculture and is affiliated with the Agricultural
Extension Service in each state. Hence, if you want to
check out your chances of obtaining employment as a
fieldman, your best bet is to call or write the County
Agricultural Extension Agent in the county where you live
(or intend to live). He’ll know about the DHIA program and,
in fact may be the person who manages it and hires the
fieldmen in your area. And if he doesn’t, he’ll know who


Once you’ve been hired an
experienced fieldman will take you out on his or her route
a time or two and quickly teach you the essentials of the
job. Then–after you’ve worked a couple of weeks on
your own and seen what the job entails (and you’re sure you
want to stay with it awhile)–your local association
will send you to fieldman’s school (probably at the land
grant university in your state) for a week of instruction.
There, you’ll learn about DHIA work in greater detail and
be given a broad introduction to the care, feeding, and
breeding of dairy animals . . . after which you’ll return
to the area in which you live to carry out your duties as
an experienced, trained milk tester.

Rates of Pay

You won’t accumulate a fortune as a fieldman . . . but
then, you won’t exactly starve, either. Rates of pay vary
from one local association to another and are generally
higher in the Northeast and Far West than the Midwest or
South. Here in Wisconsin (where rates are about average), a
typical wage is $10 per day–your “basic supervision”
fee–plus 11¢ per cow . . . which means that a
fifty-cow herd can net you $15.50 (plus two home cooked
meals) for a day’s work. And that’s just the beginning.

You see, owner-samplers –dairymen who aren’t
interested in having official DHIA test records, but who DO
want to know how much milk each of their cows produce (and
how much butterfat is in that milk)–can easily double
a fieldman’s wages.

Here’s how it works: Let’s say you have three
owner-samplers (with herds of 30, 60, and 90 cows) on your
day’s route in addition to the fifty-cow herd mentioned
above . . . not an unlikely scenario. OK, on your way out
to perform evening tests you’ll leave a barnsheet–and
a box of sample bottles–in each owner-sampler’s
milkhouse. Then, in the morning–on your way to the
lab–you’ll pick up the sample bottles that you
dropped off the night before, bring them in for analysis,
and receive a tidy 11¢ per cow (but no supervision
fee) for doing so. Which makes your day’s wages $35.30 . .
. not $15.50. (Quite a boost, considering that you’ve
hardly gone out of your way to earn it.)

Between basic supervision fees and owner-sampler income,
then, you should have no trouble making about $400 to $700
per month as a fieldman (assuming you work five days a
week) . . . not counting the money you’ll save by eating
away from home most of the time!

Fringe Benefits

Although the DHIA testing program is sponsored by the
Department of Agriculture, it’s actually organized and run
on a local level by participating dairymen, who elect a
governing board from among their own ranks. Consequently,
as a DHIA milk tester, you work for the dairymenthemselves. (You’re not an inspector or
a salesman, so your presence on a farm is never an
imposition or an unwanted intrusion.) In effect, the
dairyman is inviting you to his farm once a month to
work with him.

This–in turn–provides the basis for one of the
finest “fringe benefits” of the job: personal friendship.
By getting to know the farmers you work with, you’ll
establish enduring personal relationships . . .
and–at the same time–acquire something else
that every newcomer to country life desperately needs:

Most dairymen like their work and like to talk about it.
(Whether or not you’ve got the gift of gab, the words will
flow . . . believe me!) So use that fact to your advantage
by asking all those questions you have about dairy cattle
and other farming subjects . . . you’re sure to get plenty
of free professional advice!

Also, if you’re looking to buy a calf–or some hay for
use as mulch in the garden–by all means ask. You’re
close to the source of both. And are you in the market for
a piece of land? One of the dairymen you work with may have
acreage to sell, or know of a neighbor who does. (And if
you’re looking for a dog or cat, you’ll have to learn to
say no unless you want dozens of them!)

DHIA field work–as you can see–gives you direct
and easy access to the ordinary activities and daily flow
of country life. Which is something you can’t say about
very many other jobs.

Additional Advantages

One nice feature of this line of work is that it leaves you
free during the middle of the day (from 10:00 or 10:30 a.m.
to 4:30 or so) to raise a garden, build a house, write a
book, or do anything else you want. There’s also a good
chance that you can adjust the length of your workweek to
fit your economic circumstances. For instance, some
fieldmen–who look upon milk testing as a source of
both income and social life–like to work seven days a
week . . . while I prefer to go out only three or four.

Then too, one fieldman’s job could easily be divided
between two people, each of whom takes on half the usual 20
to 24 herds to be tested per month. It shouldn’t be too
difficult to find an association manager who’ll agree to
such an arrangement. If he needs help and thinks you and
your partner will be dependable, you’ll probably get the
job . . . because in most areas, good fieldmen are hard to
find and the turnover is high. (Thus, even as a job
applicant you can deal from a position of some
strength when making such a proposal.)


The fact that fieldmen tend to come and go may suggest to
you that the job has its disadvantages . . . and you’re

The most obvious drawback–ironically–is the
work schedule itself. Getting up before the roosters each
morning isn’t everybody’s idea of fun . . . despite the
fact that the world’s always fresh–and often
glorious–just as the sun comes over the horizon.
Nonetheless, farmers do milk their cows early in
the morning and early in the evening (usually at 6:00 and
6:00), and you have to be there, even if the roads are bad
and it’s 25° below zero.

DHIA field work also has a disruptive effect on family
life. Of course, you may–if you live
alone–relish eating breakfast and supper at somebody
else’s table all the time . . . but if you live with family
or friends, you–and they–may come to regret
your routine absence at mealtime.

Then too, one of these field jobs can put a real damper on
your nighttime activities. You won’t be able to get started
on anything before 8:00 or 8:30 p.m. And you’ll have to
curtail each night out mighty early if you want to wake up
feeling rested before dawn the following morning.

One more thing: Cows are veritable volcanoes of organic,
highly odorous activity. In other words, they smell. You
can get used to this, of course, if you want to . . . but
not everyone wants to.

The Ideal Job?

Still and all, if you’re looking for something that’ll
allow you to [1] provide an important service, [2] meet a
lot of interesting people, [3] learn a good deal about farm
life, and [4] earn a livable wage in the process, you’d
have to search far and wide–in my opinion–to
beat DHIA field work. (Especially if you enjoy eating out!)

Come to think of it, I’d probably have moved to the country
a lot sooner if I’d known–before I got
here–that there was a job waiting for me as a DHIA
milk tester!
