The Fiber in Cow Rations
There must be some way to take
the “fib” out of fiber. Whether we
use the word in relation to human
food, as in Fruit an’ Fiber, or in the
context of dairy nutrition, as in CF,
NDF, and ADF, it’s a confusing
term. The confusion should be
sorted out.
Fiber is an analytical term for
one of the important nutrients in
all feeds for cows as well as
humans. In cow feed it’s often
related to the term “roughage,”
meaning almost anything we feed
cows except grains and grain
byproducts. This relationship is
false, because nutrient fiber is
found in many feeds. Technically
the term refers to the analytical
measure of the cell structure -
Lignin, cellulose, hemicellulose
and pectin.
Lignin is indigestible and

reduces the digestibility of the
other fiber components. It is the
primary limiter of forage
digestibility. The other com
ponents are digestible, but at
slower rates than starches,
proteins and sugars. The in
dividual components of the fibers
in cow feed must be considered, in
formulating rations. They are
separated in the laboratory and
reported as crude fiber (CF),
neutral detergent fiber (NDF),
and acid detergent fiber (ADF).
Crude fiber (CF) fails to
separate the digestible parts of the
cell wall constituents from the
indigestible parts. These com
ponents are often “guestimated,”
but can be too rough for a finely
tuned feed program. So Dairy
nutritionists use lab techniques to
separate the undigestible lignin

from the more digestible cellulose,
hemicellulose and pectins. Hence,
the terms NDF and ADF have now
become important terms in feed
formulation.
NDF fiber relates to the intake of
feed by the cow. It contains all the
fiber elements that take up room in
the rumen, but are slowly digested.
ADF fiber relates to the
digestibility of forages, because it
still contains all of the indigestible
portions of the fiber fraction,
(lignin), plus some very slowly
digestible cellulose.
Why be concerned about these
little niceties of laboratory
analyses? Especially when we are
talking about cell walls, not the
really important stuff like energy,
protein, vitamins and minerals. ,
Well, since these fiber com
ponents influence both intake of
forage feeds as well as the
digestibility of the forages, they
become vital to the nutritional
balance that directly effects milk
production. It “ain’t just hay”
we’re talking about now.
We are getting very picky and
choosy about the kind of stuff that
makes up our hay, haylage,
pasture and anything else that
comes under the heading of forage
for cattle.
The great variation in forage
quality is universally recognized,
but often underplayed in actual
feeding. We still try to wing it by
guessing at the actual intake of
forages, based on what we have in
the hay mow or silo. Of course,
once the stuff is in storage, what
can we do but feed it?
The big secret here is to control
quality at harvest and storage
time. The only other control is to

analyze what you have, and
balance it accordingly. This
requires a competent
nutritionalist, not a salesman.
Unless, of course, the salesman is
a trained nutritionalist working for
you, with results as his goal. A
competent dairy nutritionalist will
insist on forage analysis, as well as
an educated “eyeball” of your
forage quality.
Some dairy nutritionists are
giving high priority to the NDF and
ADF content of the feeds they
prescribe for high production.

Equity is the net retained

has performed the important
function providing the necessary
capital to finance the cooperative.
Checks totaling over $2.1 million

7,000 dairy farmers. This check
represents that portion paid in

This equity allocation to
members was made at the rate of
29.7 cents per hundredweight (100
pounds) of milk marketed through
Dairymen during fiscal year 1985.
“Members can look upon this
current distribution of equity as
the final settlement paid to them
for the milk they marketed,” said
James E. Mueller, chief financial
officer. “We are pleased to be able
to return our members $97.70 of
each $lOO in sales for milk
marketed in fiscal 1985.”
Dairymen markets ap
proximately 70 percent of its
members’ milk to processors of
milk and dairy products in the
East and Southeast United States.
The remaining 30 percent is
marketed through the
