MUN Technology Can Help Profits
(Continued from Page A2B)
Generally, he found that milk
production decreased as MUN
levels increased and that produc
tion increased as MUN decreased.
The question then, is how to use
MUN values and production
levels.
MUN values and production
levels surely have a common link.
The link, George believes, is made
by looking at what ration compo
nents tend to have the largest
impact on MUN values.
The ration components are pro
tein and carbohydrates. More
specifically, we must look at what
happens in the rumen itself.
Chart two looks at radons fed
over the same time period as the
previous production records.
George decided to look at com
ponents and values that can actu
ally be measured in a feed analyti
cal lab, which include percent CP,
percent soluble protein, and per
cent starch, 4o look at the ration.
George believes that the
amount of soluble protein, and
starch together in the rumen must
be in balance to enhance optimum
utilization of both. He decided to
translate these values into grams
of soluble protein and pounds of
starch provided to the cows.
As these two components are
broken down in the rumen; the
Capacities vary depending upon:
We still build a lot of 16’, 18’, 20’ moleture, lenath of cut, distribution,
and 24’ diameter silos. ra,e °* fl " lns ’ ,ypBB * ' o,BflB '

ratio of grams soluble protein to
pounds starch was developed to
see what effect that relationship
had on MUN levels and
production.
The September 12,1995 figures
represent what was fed to achieve
production and MUN figures on
10/4/95. The 10/10/95 is the ration
that generated 11/3/9S production
and so on down the chart
George found it interesting that
as this ratio wait up, MUN went
up and production went down.
This told him that increasing
MUN values meant that we were
wasting protein. Graph B shows
this relationship.
Increasing die ratio of soluble
protein to starch will increase
MUN values, and when that hap
pens. milk production goes down.
Finally, he felt confident in the
way MUN values were affected
by soluble protein and starch in
our rations. He decided that this
relationship could produce accept
able MUN values and enhance
production.
After the October 1996 test that
saw a sharp rise in MUN value,
and a drop in production, the
ration was changed to keep the
ratio of grams soluble protein to
pounds starch between 75 and 85.
This can be accomplished by
altering percent CP, percent solu
ble protein, percent starch, or a
POSSIBILITY!”

combination of the three.
The four months that followed
had a steady increase in produc
tion that coincided with a leveling
of acceptable MUN values, and
the soluble protein to starch ratio
between what 75 and 85.
Dairymen always want to know
how this all can affect their pock
et books. “On our farm, using
MUN has made a lot of money,”
George said.
To illustrate this we look at the *

Good Genes
Make A Big Difference
Chore-Time's MODEL C2* feeder is the result of more
than 40 years of innovative breeding. Here are a few of the
traits you get from the Chore-Time bloodline:
• Labor-saving Feed Windows.
• Chick-friendly Feeder Grill Design.
• Unsurpassed feed converting ability.
NEW HOUSE INCENTIVE
Empire Kosher Poultry is offering an incentive for
new broiler houses. A $.0025/lb bonus will be added
to the pay of all new houses for the first 15 flocks.
The new houses will be state-of-the-art facilities.
The new house incentive is for a limited time. When
a designated number of houses are completed the
new house incentive will be discontinued. If you
have ever wanted to get into the broiler business,
now is a great time.

“I am sure that not every farm
has this potential for increased
earnings, but I also believe that
some have more.”
George also believes MUN can
and should be used by anyone
interested in doing a better job
feeding their herd.
One must remember, that not all
feeding systems are the same and
you must tailor programs and
technology to make it work on
your farm.
One other thing that he said he
would like to emphasize is that the
relationship of soluble protein to
starch or nonstructural carbohy
drate is what is important, not the
crude protein. Some farms with
high hay feeding may need higher
crude protein to balance out the
starch supply.
